In this case, the vehicle using the ecvt (hereinafter, referred to as the vehicle using the ECVT) does not require any gear change operation or clutch operation by a knight. Therefore, the ECV has recently been incorporated into various However, in the case of a vehicle employing the ECVT, the knight cannot selectively change the gear ratio (4) in excess of the setting τ given in the gear ratio chart. Here, for the vehicle using the ECVT In fact, it is difficult for the Cavaliers to effectively start the engine brakes as they please. More specifically, it is difficult for the Cavaliers to start a vehicle with a range that is strongly exceeded by the gear ratio chart... and then use the ECVT vehicle. In other words, it is difficult to force down the division. 1) Operation 'So when the handle exceeds the other _ = day, the acceleration of the vehicle must be increased more than in the normal state. In the circumstances, a vehicle has been proposed in which the gear ratio can be continuously used to adopt the ECVT, and the so-called AT mode 128766.doc 200848637 and the gear ratio thereof can be automatically changed by the knight Depending on the situation, the two modes of the MT mode are selected.

X, [Effect of the present invention] According to the present invention, a forced downshift operation can be easily achieved in the ΑΤ mode. [Embodiment] <<Example 1>>> "Structure of Motorcycle 1" In the present embodiment, the present invention will be described by taking a so-called scooter type motorcycle 1 as an example to explain the present invention. An example of an embodiment. As shown in the figure, the motorcycle has a handle 4, a power unit 2, and a wheel 3 for use as a drive wheel. The power unit 2 and the rear wheel 3 are connected to each other via a power transmission mechanism 6. (Manipulation Handle 4) FIG. 2 is a schematic structural view of one of the manipulation handles 4. The operating handle 4 has a handlebar 4d coupled to an operating head tube (not shown). The operating handle 4 includes a left grip portion that is positioned at the left end of the handle bar and a right grip portion that is positioned at the right end of the child's handle 4d. The right grip portion knife 4b is pivotable relative to the handle bar 4d. When a knight pivots the right grip portion 4b, an unillustrated throttle valve can be operated to control a throttle opening 128766.doc 200848637. The brake lever 4c is disposed adjacent to the respective grip portions 4a, 々b. When the rider operates the brake lever 4c, the brake of the motorcycle 1 (not shown) can be actuated, and as will be described later, a brake signal 104 is output to an ECU 5. A switch box 40a is disposed at a right side portion of the left grip portion. The switch box 40a has various different operation switches such as an upshift switch 41, a downshift switch 42, a mode temporary change switch 43, and a mode select switch 44. As shown in FIG. 3, various operational opening relationships such as the upshift switch 41, the downshift switch 〇, the mode temporary change switch 43, and the mode selection switch 44 are clamped to the left hand of the knight. 〇之姆 refers to the location where the switches are operated. More specifically, the various non-fourth open relationships are arranged to be slightly inclined downward toward the top surface of the back-opening of the open box, that is, the various operational open relationships are disposed in the switch box 4〇a. Facing the surface of one of the knights. However, the present invention is not limited to this structure. For example, some of the operations, such as the riser switch 41, can be configured to view the rear surface of the switch box 4A of the 1-4 when viewed from the position of the knight so that the switches can be made by the index finger. For example, it is possible to arrange the liter switch (41) in the rear surface when viewed from the position of the knight and to arrange the down switch 42 in the surface facing the knight. In other words, the upshift switch 41 is operated by the index finger and the downshift switch 42 is operable by the thumb 6Ga operating system. Furthermore, all of these operating switches can be configured to view the rear surface of the switch box 40a at the position of the I@攸 knight to operate by the index finger. 128766.doc 200848637 In this embodiment, the various different operation switches (the switches 41, the downshift switch 42, the mode temporarily change the switch selection switch 44) have a push button type and a so-called button type switch These various *same operations can be formed with push rods. Furthermore, 1 = the switch can be a rotary switch, and the knob is moved more. And between the hearts > As shown in FIG. 3, the lift switch 41, the downshift switch 42 and the mode are temporarily changed among the various operation switches, and the ^^, Λαα genre switch 43 is set to be closest to the ride. In other words, the upshift switch 4丨, the drop switch (4), and the mode temporarily change „43 is set at the outer side of the vehicle width J. This mode temporarily changes the switch 43 to be positioned at the lift switch. 41 is between the downshift switch 42. The mode selection switch 44 is disposed at a position where the ratio switch 41, the downshift switch 42 and the mode temporarily change the switch 43 and the distance of the hand opening are further. For this mode, the selection frequency is lower than the upshift switch 41, and the downshift switch is similar to the second mode, and the frequency of use of the switch 43 is changed. As described above, the frequency "6 liter slot switch 41 is used. The downshift switch 42 and the mode temporarily change the open=good system is set closer to the left hand 6. The switches can be used at the position of the valley; the location of the 'outside' _ type selector switch 44 is not set. Feeding is limited to the left vertical knife & for example, the mode selection switch 44 can It is disposed on the left side of the right grip ^4b. More specifically, 'another switch box can be set to the left side of the boring tool and the mode selection switch 44 can be positioned. In this alternative version, the mode selection switch 128766.doc 200848637 44 is preferably positioned such that the index finger of the knight's right hand can operate the switch 44. (Power unit 2) is shown in FIG. An engine 1 用以, an electronically controlled transmission 20, a centrifugal clutch 3〇, and a speed reduction mechanism 31 are shown as a driving source. The transmission 20 has a gear changing mechanism 21 and a function as an actuator The electric motor 22 is used to change a gear ratio of the gear changing mechanism 21. The gear changing mechanism 21 has a main sheave 23 and a pair of sheaves 24. The main sheave 23 is installed. One of the output shafts 12 of the engine 1 rotates with the rotation of the output shaft 12. A belt 25 having a substantially v-shaped cross section is wound around the main sheave 23 and the auxiliary sheave 24. The motor 22 is attached to the main sheave 23. For the belt 25 to be wound The width of the belt groove of the main sheave 23 thereon is changed by the motor 22. Thereby, the gear ratio of the gear changing mechanism 2 can be continuously changed. More specifically, the The gear ratio of the gear changing mechanism 21 can be changed steplessly. The auxiliary sheave 24 is connected to the speed reducing mechanism 31 via the centrifugal clutch 3〇. The speed reducing mechanism 3 is formed by forming a belt and a chain. A power transmission mechanism 6 such as a drive shaft is connected to the rear wheel 3. The centrifugal clutch 30 is connected or disconnected according to a rotational speed of the auxiliary sheave 24. More specifically, if When the rotational speed of the secondary sheave 24 is less than a predetermined rotational speed, the centrifugal clutch 3 is in an open state. Therefore, the rotation of the sub-groove 24 is not transmitted to the rear wheel 3. On the other hand, if the rotational speed of the secondary sheave 24 is equal to or greater than the predetermined rotational speed of the predetermined number, the centrifugal clutch 3 is placed in the connected state. Therefore, the rotation of the sub-groove 24 is transmitted to the rear wheel 3 via the centrifugal clutch 3, the deceleration mechanism 3i, and the power transmission mechanism 6. Thereby, the rear wheel 3 can be rotated. <<Control block of motorcycle 1>>

ϋ One of the control blocks of the motorcycle will be described next with reference to FIG. 4. As shown in Fig. 4, the motorcycle i is mainly controlled by a coffee (electronic control unit) 5 as a control system. The ECU 5 includes: a memory 57 for storing various different setting values, a CPU (Central Processing Unit) 5A as a calculation portion, and a drive circuit 56. The CPU 5 has a _ Μ τ mode temporary selection portion 5 - a change mode selection portion 52, a release signal output portion 53, an AT mode return portion 54, and a gear ratio control portion 55. A variety of different sensors and switches or similar components are attached to the ecu $. More specifically, a mode temporary change switch 43, a mode selection switch 44, an upshift switch 41, a downshift switch 42, an accelerator opening degree sensor 33, a brake lever 仏, an engine speed sensing μ The _ wheel position picking sensor 26, a pair of sheave rotational speed sensor 27, and a vehicle speed: 32 are connected to the ECU 5. " This mode temporarily changes the switch 43 to output a mode change signal (8) to the ECU 5 when operated by the knight. The mode selection switch 44 outputs a mode selection signal 1〇2 to the EC1J 5 when it is controlled by the knight. The σ' field opening degree sensor 33 detects the throttle opening degree of one of the motorcycles 1. The throttle opening sensor 33 outputs the detected throttle opening degree to the Ecu $ as the j door opening degree 彳§ number 1. The brake lever 4c is pulled out by the knight 128766.doc 15 200848637 A brake signal 104 is sent to the ECU 5. The upshift switch 41 outputs an upshift signal 105 to the ECU 5 when operated by the knight. The downshift switch 42 outputs a down-slot signal 106 to the ECU 5 when operated by a rider. The engine speed sensor 11 detects a rotational speed of the engine cymbal. The engine speed sensor 11 outputs the detected rotational speed of the engine 1 to the ECU 5 as an engine speed signal 丨09. The sheave position detecting sensor 26 is a sensor for detecting the gear ratio of the gear changing mechanism 2 j . More specifically, the sheave position detecting sensor 26 detects the width of the belt groove of the main sheave 23. For example, if the main sheave 23 is formed by a fixed sheave body and a movable sheave body movable relative to the fixed sheave body, as embodied in the embodiment, the sheave position The detection sensor 26 can detect the position of the one relative to the fixed sheave body. The sheave position detection: = 26 outputs a position of the movable sheave body to the Ecu 5 as a sheave position signal 1 1 〇. θ "" The sub-groove rotation speed sensor 27 detects the rotation speed of the sub-groove 24 . The sub-groove rotation speed sensor 27 outputs the rotation speed of the sub-slot 24 detected by the cutting to the ECU 5, and then the sub-slot rotation speed. The vehicle speed sensor 32 detects the motorcycle. i - the speed of the vehicle. ★Hai vehicle speed sensor 32 outputs the detected vehicle speed to _::2 速度 speed sensor 32 can also be used to detect the =: rotational speed of the sensor. However, the vehicle speed sensing is used, for example, to detect another vehicle speed by means of a 128766.doc 200848637 rotational speed of the wheeling shaft of the speed reduction mechanism 31. Furthermore, the vehicle speed sensor 32 can also be another sensor that detects the speed of a vehicle by detecting the rotational speed of one of the front wheels. (Introduction to Control by the ECU 5) The ECU 5 controls the engine 10. More specifically, the ECU 5 calculates the engine speed as a target value based on the accelerator opening degree signal 103, the vehicle speed signal 112, and the like. The Ecu 5 controls the engine by controlling the ignition timing of one of the engine ignition systems (not shown), the amount of fuel supplied to the engine 1 and the like, and simultaneously monitoring the engine speed signal 1〇9. (7) The rotational speed or the like is controlled to the target engine speed. Furthermore, the ECU 5 controls the transmission 2〇. More specifically, the Ε (: 利用 1 uses the engine speed signal 1 〇 9, the vehicle speed signal ι ΐ 2, etc. as a target gear ratio. The ECU 5 utilizes the sheave position signal 110 and the like. The current gear ratio of one of the transmissions is determined. The Μ5 outputs a PWM (pulse_width modulation) signal 1〇8 to the drive circuit according to the calculated target gear ratio and the determined current gear ratio. The drive circuit 56 applies a pulse voltage to the / motor 22 corresponding to the input pWM signal 1 〇 8. Thereby, the gear ratio of the transmission 2 can be controlled to the target gear ratio. In the example, an example in which the motor 22 controlled in a PWM manner is used as an actuator for changing the gear ratio of the gear changing mechanism 21 will be described as follows. However, in the present invention, the transmission 20 is changed. The type of the actuator of the gear is not limited. For example, the actuation of the ω wheel ratio to change the shift is 'can be controlled by a method of pMA (pulse amplitude modulation) 128766.doc 17 200848637 Electric motor. Again, to change The gear ratio of the transmission 20 can be actuated as a stepper motor. Further, the actuator for changing the w-wheel ratio of the shifting gear 20 can be a hydraulic actuator or the like. The control of the gear ratio of the transmission 2() will be described first. The selection of the gear change mode will be explained first with reference to Fig. 5. (Selection of gear change mode) In the motorcycle 1, 'selectable ^ mode, manual position and one 2 MT mode. As shown in Fig. 5, the AT mode, the manual MT mode, and the =Machine mode can be selected by the knight operating the mode selection switch μ. As shown in Fig. 4, when the knight is # When the mode switch 44 is made, the mode is output from the mode selection switch 44 to the KM. More specifically, the mode selects the change of the mode gear to the output of the gear 5. Mode selection section 52::=Selection signal 102 is input to the dry, inch. Λ w wheel change mode is not as shown in Fig. 5 - the current gear change mode change mode 予, change or pay. For example, if At present, the gear gas system is 6 hai ding, and the gear is selected in this mode. Off 44-times and refinement by the Cavaliers know the singer again - the second grip... automatic MT mode. When the ride will change the mode from the automatic wheel, the mode is selected at this time (10) 杈. When the knight again - When the 4 4 is exhausted, the gear change mode is changed to the previously selected AT mode. The formula will be operated from the hand: the type selection switch 44 is operated and:: When should the gear change system (4) ^^ When phase 2 is input, when the Tiankouhai (four) wheel change mode is changed by the above method 128766.doc -18- 200848637, the gear ratio control section is changed to control the section (4)..., the changed gear is changed + the masterpiece is changed 20 gear ratio. For another example, you can: = change one instance. Or, check and select: from: select the mode switch of the AT mode and use the ^ (four) automatic Μ mode to select the manual Μ 捃 、, seven 汗 〕 以及 以及 以及 以及 以及Another mode selection switch. "AT mode" The AT mode is a gear ratio of the transmission 2 藉 by = according to the driving state of the motorcycle 1, in other words, the "AT mode," is a type in which the ω wheel of the transmission 20 ,,,,motorcycle! The driving state is automatically changed without a paragraph. For example, the 'this AT mode' may be at _, flying to tune the mode in which the gear ratio of the transmission 20 is continuously and automatically changed according to a predetermined gear ratio map. The δ memory 57 in the ECU 5 stores a relationship defined between the traveling state of the motorcycle 1, such as the vehicle speed of the motorcycle 1, the engine speed, and the throttle opening, and the gear ratio. The gear ratio control portion 55 shown in Fig. 4 calculates the target gear ratio based on the gear ratio map and the vehicle speed signal η] and the engine speed signal 109 and the like. The gear ratio control portion 55 outputs a PWM signal 1〇8 to the drive circuit 56 based on the calculated target gear ratio, the sheave position signal 110, and the sub-groove rotational speed signal lu. The drive circuit 56 applies a pulse voltage corresponding to the PWM signal 108 to the motor 22. Thereby, the motor 22 is driven and the width of the belt groove of the main sheave 23 is adjusted. Therefore, the gear ratio of the transmission 128766.doc -19- 200848637 20 is changed to the target gear ratio. "MT Mode" On the other hand, the MT mode is a mode in which the gear ratio of the transmission 2 is automatically or manually changed among a predetermined plurality of gear ratios. In the MT mode, a gear ratio in which the transmission 2 is changed by the knight operating the operational switches, such as the upshift switch 4, the downshift switch 42 or the like, etc. The mode is "manually silent".

That is, in the manual MT mode, the change of the gear position is performed by the knight. Additionally, the "MT mode" may be referred to as a dummy mode to distinguish from a normal manual shift mode in which the gear ratio is varied between a plurality of gears. The Dingche JLVi i mode is more specific. As shown in FIG. 6, in this embodiment, five almost fixed gear ratios, that is, a first speed, a second speed, a third speed, - the fourth speed and a fifth speed are set in accordance with the order from the lowest speed. In addition, the respective gear ratios of the first to third brothers can be fixed by the whole. Or go, _1 _方楚.. / 者 ^ 专用 ^ wheel ratio can be changed according to, for example, engine speed. More specifically, the individual gear ratio of the first five speeds is, for example, the solid wheel ratio is positioned to follow The top speed is n Λ ^ and the closer to μ is S 疋. In this manual ΜΤ mode, in principle, the gear ratio does not change, except for the off, the "I knights operate these operations as old as In the manual MT mode, such as the upshift switch 41, the downshift switch 42, etc., in principle, the respective ratios are not automatically changed between the transmission 20 J wheel ratios, not the knight. Operating such operations 128766.doc -20- 200848637 switches such as the upshift switch 41, the downshift switch 42, etc. downshift The execution may be forcibly performed for the purpose of, for example, avoiding the motorcycle! deceleration state; the engine stall or the like. For example, 'for the example shown in FIG. 6, if the motorcycle is first At the beginning of the journey, before the upshift switch 41 is operated, the transmission 2. The wheel ratio will stay at the first speed. If the knight operates the upshift at point A = 4! ', as shown in Fig. 4 - upshift The signal (9) is outputted from the upshift switch to the ECU 5. When the upshift signal 1() 5 is input to the clerk $, the gear ratio control portion 55 of the ECU 5 outputs a pwM for changing the gear ratio from the first speed to the second speed. Signal (10) to the drive circuit 56. The drive circuit 56 applies - a pulsed electrical motor corresponding to the p-side number (10) to the motor 22. Thereby, as shown in Fig. 6, the w-wheel ratio of the transmission is falsified to the second speed of s. Similarly, if the upshift switch 41 is further operated at point B, then the gear ratio of the transmission (10) will change to the third speed. On the other hand, if the downshift switch 42 is operated at point C, a downshift signal 106 will be output from the downshift switch 42 to the Ecu 5 as shown in FIG. When the downsizing signal 1()6 is input to the Ecu 5, the gear ratio control portion 55 of the Qing 5 outputs a gear ratio for changing the transmission ratio from the fifth speed to the fourth speed. PWM signal (10) to the drive circuit %. The drive circuit 56 applies a pulse voltage corresponding to the PWM signal ι8 to the motor 22. Thereby, as shown in Fig. 6, the gear ratio of the transmission turns from the fifth speed to the fourth speed. π automatic MT mode" 128766.doc -21 - 200848637 In the MT mode, a gear ratio in which the transmission 20 is automatically changed by the gear ratio control portion 55 between a predetermined plurality of gear ratios The mode that does not require the knight to perform any operation is the "automatic mode".

As exemplarily shown in FIG. 7, if the automatic μτ mode is selected by the gear change mode selecting portion 52, the gear ratio of the transmission 20 is automatically changed in accordance with the change of the running state of the motorcycle 1, without borrowing Any operation by the knight. However, in this automatic ΜΤ mode, unlike the ΑΤ mode 13, the gear ratio is not continuously changed. In other words, in the automatic MT mode, unlike the Ατ mode, the gear ratio is not changed in a stepless manner. That is, in the automatic MT mode, the gear ratio of the transmission 2 is automatically changed in the predetermined gear ratios. Additionally, in the automatic MT mode, the gear change timing has different settings in accordance with, for example, the throttle opening degree and the like. More specifically, if the knight greatly opens the throttle valve (i.e., 'the throttle opening degree: large') to accelerate the motorcycle more quickly, the gear change is performed at a higher speed. On the other hand, if the knight opens the throttle valve a small amount (i.e., the throttle opening degree: small) to accelerate the motorcycle more slowly, the gear change is performed at a lower engine speed. In this downshifting operation, the gear shifting sequence similar to the upshifting material has different settings depending on, for example. Also looking for (MT downshift mode) 概 an overview of the downshift mode, in this embodiment, as shown in Figure 5, AT 槿Α 兮 兮 兮 秘 秘 内 八 八 八 101 101 101 101 101 101 101 101 Temporary change of the 杈 style | Do not leave the day, then temporarily choose 128766.doc -22- 200848637 MT down slot ju + ju. Here, the selected "Tongriji" gear ratio of the transmission 20 = the heart wheel ratio control portion (4) is changed to one of the gear ratios existing in the range of the low value (10) W), i φ ^ 者 where the low value The gear ratio is in the

The plurality of gear ratios (the first speed to the fifth speed) are lower than the speed-to-current gear ratio. If the mode is temporarily changed by the knight in the downshift mode of the town, the gear ratio is changed to a low value, which is lower than the current gear ratio of the transmission 2 (). Gear ratio. When the release signal 107 is outputted by the demodulation wheeling portion 53 shown in Fig. 4 in the Μτ downshift mode, the mode returns from the Μτ downshift mode to the AT mode. For example, in this MT mode, the knight can selectively change the gear ratio of the transmission. Conversely, in this Ατ mode, the knight cannot selectively change the gear ratio of the underrun k speed 20 because the gear ratio of the transmission 2 is automatically changed. The MT downshift mode is a gear change mode set in a case where the AT mode is selected such that a kickdown operation or a start engine brake can be achieved by a simple operation of the knight. In the present embodiment, the gear ratio control portion 55 is used to change the gear ratio of the child gear 20 to a current gear ratio closer to the transmission 2 且 and exists in the predetermined plurality of gear ratios ( An example of a gear ratio in a low range of values from the first speed to the fifth speed that is lower than the current gear ratio of the transmission 20. However, the invention is not limited to this example. For example, by the gear ratio control portion 55, the gear ratio of the transmission 20 can be changed to a gear ratio which is lower than the current gear ratio which is present in the low value range and the shift speed is 20 The gear ratio of the plurality of gear ratios (first speed 128766.doc -23-200848637 degrees to fifth speed) that is closest to the current gear ratio of the transmission 20 is closer to the current gear ratio of the transmission 20. More specifically, with the gear ratio control portion 55, the gear ratio of the transmission 20 can be changed to a gear ratio that is lower than the current gear ratio of the transmission 20 in the low value range. The gear ratio that is lower than the current gear ratio of the plurality of gear ratios (first speed to fifth speed) that is closest to the transmission 2〇 is closer to the current gear ratio of the transmission 2 in the first stage. . Further, with the gear ratio control portion 55, the gear ratio of the transmission 20 can be changed to a gear ratio which is lower than the current gear ratio existing in the low value range compared to the transmission 2 The gear ratio of the predetermined gear ratio (the first speed to the fifth speed) that is closest to the current gear ratio of the transmission 2〇 is closer to the current gear ratio of the transmission 2 in two stages or more. . Alternatively, the knight can set the downshift amount. For example, if the knight wants to create a faster drive, the knight can choose a mode with a larger downshift. The right 4 knights cause a slower drive, so the knight can choose a mode with a smaller drop. Furthermore, a plurality of modes can be provided to temporarily change the switch 43. For example, it is possible to provide a mode temporary change switch 43 having a smaller downshift amount and a further mode temporary change switch c having a larger downshift amount. ''Details of MT Downshift Mode') The following will mainly explain the downgrade mode of the town with reference to Fig. 8_13. Here, an example will be described in which the Μτ downshift mode is a manual gear change mode in which the transmission The gear ratio of 20 corresponds to the operation of the knight: the operation of the switch is performed by the gear ratio control portion 55 between the gears: 128766.doc -24· 200848637 gear ratio (first speed to fifth speed) However, the MT downshift mode may be a gear change mode in which the gear of the transmission transmission is given by the gear ratio control portion 55 at the predetermined plurality of gear ratios in accordance with the motorcycle R traveling state ( Automatically changing between the first speed and the fifth speed. As shown in Fig. 8, if the mode is temporarily changed in step 81 and the switch 43 is selected and the gear changing mode selection portion 52 selects the Ατ mode, the MT The downshift mode is temporarily selected. More specifically, a mode change: the number 101 is output to the decimating mode temporary selection portion 5 of the ECU 5. When the 改变 change signal 1 〇1 is input to the Μτ mode When the portion 51 is temporarily selected, the ^MT^ type temporary selection portion 5丨 commands the gear change mode selection portion 52 to select the MT downshift mode. Thereby, the gear change mode selection portion 52 selects the MT down-slot mode. At the same time as the selection, the gear ratio of the speed change 20 is changed to a gear ratio by the gear ratio control portion 55, wherein the gear ratio is closest to the current gear ratio of the transmission 2 and exists therein. a predetermined plurality of gear ratios (the first speed to the fifth speed) being lower than a lower value range of the current gear ratio of the transmission 20. If, as shown in FIG. 13, the mode change signal 1〇1 is input at a point eight positioned between the fifth speed and the fourth speed, and the gear ratio is changed to point B representing the fourth speed. 'If the gear of the transmission 20 is matched to one of the predetermined plurality of gear ratios, the first speed to the fifth speed, when the mode temporarily changes the switch 43 is operated, then it can be maintained The gear ratio is at the predetermined plurality of gear ratios The first gear ratio (first speed to fifth speed) coincides with the current gear ratio of the 128766.doc -25-200848637 heart speed transmitter 20. At this time, the down-slot operation does not temporarily change the operation time of the switch 43 in the mode. It is executed substantially. However, since after that, the gear ratio of the transmission 2 is maintained at the current ▲-匕 □ this phase & in the AT mode in which the gear ratio is changed toward the up range 'The downshift operation is performed at a later time. As shown in Fig. 8 7', if it is determined that the mode temporarily changes the switch 43 to be operated in the Μ 降 4 4 core nucleus, the downcast operation can be performed. (Step is called. For example, if the mode temporarily changes the switch 43 to be dropped at the point c of Fig. 13, a mode change signal (8) is output to the coffee 5. When the mode change signal 1〇1 is output to the ECU 5, the gear ratio is downshifted from the current gear ratio by the gear ratio control portion Μ to exist at a current gear ratio than the shift (four) (the first Four speeds) one of the lower low value ranges (the third speed, at point D). u After the material is made, the gear ratio of the downshift is expected. Next, in step S3, the coffee 5 judges whether or not the motorcycle! Performing a pre-emptive action and whether it has satisfied that one of the predetermined ones associated with the motorcycle 1 determines that the predetermined operation has been performed on the motorcycle 1 and the motorcycle i is associated with the silent condition, such as The second shown in Fig. 4 is output from the release signal output portion 53 to the AT portion 54 in addition to the signal 107. When the release signal 1〇7 is input to the Μ mode return mode return portion 54, the change mode selection portion 2 selects the gear change mode to return to the Ατ mode. If the determination is not in step S3, the determination does not satisfy the operation of the motorcycle and does not satisfy the predetermined 128766.doc -26-200848637 (four) associated with the motorcycle] This mode temporarily changes the "down mode", Γ ° so ... the hai mode temporarily changes the switch 43 is operated in the MT heart: then the downshift operation is performed step by step. That is, no: the (four) mode temporary change switch 43 is operated in the Μτ downshift mode, and the downshift operation is performed. /, more specifically, if the mode temporarily changes the switch 43 in FIG. 13 after the gear is lowered to the third speed, the gear ratio is lowered from the current gear ratio. The gear to _ exists in a gear ratio (the second speed, point F) in a low value range lower than the current gear ratio (the third speed). Furthermore, if the mode temporarily changes the switch 43 at the point G shown in FIG.

When operated, the gear ratio is downshifted from the current gear ratio to a gear ratio (the first speed, point H) present in a low value range below the current gear ratio (second speed). If the ECU 5 performs a pre-operation on the motorcycle 1 at point I, for example, the mode returns from the MT downshift mode to the AT mode and the gear ratio is upshifted to, for example, point j. ''Details of Step S3'' The "predetermined condition" and the "predetermined operation" determined in this step S3 are not specifically limited to any state as long as it is available to judge that the knight no longer intends acceleration or no longer Intended to start the engine brake or the intention has been reduced. For example, as exemplarily illustrated in FIG. 9, when the throttle opening degree =: at least one of the engine speed and the vehicle speed satisfies a predetermined condition, the gear changes The mode returns to the AT mode. More specifically, when the throttle opening degree reaches a predetermined opening degree or falls below the preset opening degree or when the throttle opening 128766.doc -27-200848637 mouth is returned When the ΜΤ ΜΤ ΜΤ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - The throttle opening degree is continuously maintained for one time to return to the AT mode during a period of time between the pre-ports and the daytime interval. The port value is 'the gear change mode again, when the engine speed reaches a box-core core Sighing speed or exceeding the pre-α When the speed is changed, the tooth will return to the AT mode after the name is changed to 6 or 2%. More specifically, when the engine speed is set to a limit, the gear will be changed and the chess type will be changed. Return to the AT mode. When the vehicle speed reaches a preset I/quot; or exceeds the preset speed, the return change mode returns to the ^ni P9 mode. One of the vehicle-force speed values obtained with respect to the differential between % reaches a preset vehicle acceleration value or the vehicle acceleration value returns to the AT mode. The following is the gear change mode, as shown in FIG. When the P mode is selected by the MT mode temporary selection portion 51k to select the 降 降 降 经 经 经 砵 砵 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 ^^ 疋5, when the interval between 3 and u has elapsed after the Μτ drop mode has been selected by the =temporary selection portion 51, the gear change mode returns to the at mode.

Furthermore, for example, as shown in FIG. 12, when the M-down mode is known as (4) (4) off 41 and _ 升 难 1 () 5 is output to the coffee ^ 128766.doc • 28- 200848637 ζ w change The mode returns to the AT mode. <<: Actuation mode and effect>:> In the present embodiment, the switch is changed to: - mode to operate the mode temporarily: "off" to select the downshift mode. Because the hunting is done by the single and one door, it is also easy and quick to perform the downswing operation. 卩4 The knight only operates this mode to temporarily change the switch 43 times. Therefore, the car can be easily and continually carried out - forcibly downshifting or starting ^ Γ : For example, the eight-seven mode and the MT mode can be selected to perform the down-slot operation in the two-passenger car. However, in the conventional motorcycle example, it is necessary to take at least a W operation to downshift the gear ratio. The fan is I. Operate the mode selection switch to change from the AT mode to the 逍 mode. 2. Operate the downshift switch to perform a downshift. Therefore, not only is the gear ratio of the operator being complicated, but the operation is also difficult to perform quickly. Conversely, in the present embodiment, as described above, the downshifting operation can be easily and quickly performed in the ΑΤ mode by performing the operation of the mode (four) change switch 43. In addition, as a way to use the knight to operate or start the engine brake with a simple operation, it can be proposed that the kind of party can be paid in the AT right mode but _ no, fly dry In addition, a forced downshift mode is adopted in which the second speeder 20 is controlled to shift to a target gear ratio that is different from the gear ratio calculated from the gear change chart by a specific amount of the low value range. The forced 炊宑# ΑΤϋ + field can be performed only by an operation for shifting to the forced downshift mode of 128766.doc -29-200848637. The forced downshift mode, Nine-series AT-style. Therefore, it is necessary to have a direct sense of flexibility, or a slow deceleration of the engine, so that this forced-down operation is difficult to meet the demand. In this embodiment, 04 _ ^ Tian Hao makes the 暂时 type temporary change switch 43

Then, in accordance with this - embodiment, the MT > In the present embodiment, when the predetermined operation of the 3 thick pallet 1 has been performed on the 麈 麈, 巳 巳, and when the predetermined condition associated with the motorcycle 已 has been satisfied, The mode automatically returns from the MT down mode to the eight mode. That is, in the present embodiment, 'in the AT mode, the temporary drop in the formula with r, +, T in 4 ΜΤ^ The gear operation can be achieved by the easy and quick execution of the clipping operation. Therefore, it is used to travel in the AT mode while surpassing the acceleration of the f, the 趱 or the dry or the like. And the deceleration to start the engine brake can be easily achieved. Thereby, a relatively high drive can be achieved, and thereby an easy = drive can be performed. Therefore, the gear position change is not required normally and does not require complicated Gear change 'again' to take advantage of the knight If it is desired to accelerate or decelerate its vehicle quite strongly, the knight can select the mt downshift mode by simple operation to flexibly accelerate or decelerate the vehicle. In detail, if the throttle opening degree is set, then the engine At least the speed and the continuation of the vehicle speed satisfy the predetermined condition as shown in Fig. 9 and the mode returns to the AT mode, or if it has been set, as shown in Fig. iq, 128766.doc -30-200848637 5 ΜΤ ΜΤ 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时 暂时Since ^ is phased to the ^AT mode.

That is, the Cavaliers II map; Ϊ can reliably return to this in f A. θ can be reacted more accurately. In the column, if the knight changes the switch 43 in the Μτ downshift mode, the mode is further downshifted: Secondly, 'If the knight judges only by changing the mode to the price two =: drop = When it is not enough, it can be further reduced. :

That is, the knight can operate the motorcycle raft more freely. T Alternatively, in the present embodiment, the downshifting operation of the step can be achieved by operating the downshift switch 42 at the Μτ drop tank. ‘4 ^, when the amount of the material in the balance (4) is turned off, the gear ratio of the transmission 20 can be upshifted. μ In this embodiment, various switches, such as this mode, are temporarily changed. 128766.doc 200848637 The switch 43 is a pusher type switch. The Μ Μ 扯 + + 打 因此 can therefore easily operate the operation switches. Although it is constituted by each of the switches of the present embodiment, the fall-by-button type fine-acting switch can be a push-pull type switch. , U towel '(four) various; variable switch 4 3) can be changed by the knight's girl such as α 〇 “fruit type temporarily” as operated. The knight's thumb refers to the operation of the motorcycle 1 when it is operated by the other than the other hand.

Bi &, when the rider grips the brake lever 4c, it can move more easily than other fingers. Therefore, it is possible to achieve simultaneous operation of the brakes and various switches. Furthermore, in the embodiment of the present invention, for example, the mode is temporarily modified to be differently disposed in the left grip portion 4a, which is opposite to the inner handle portion 4b of the knight operating throttle member. Side. Therefore, the ride: the operating switches can be operated relatively easily and the throttle structure can be operated simultaneously

In this embodiment, the (four) MT mode can be selected (

Mode and the automatic MT槿6, 钵丄门 z Yuqin MT material..., formula). The knight can therefore change the gear position by selecting the manual MT mode as he wishes. On the other hand, if you want to change the gear position in a way that has a higher direct sense and is more enjoyable but does not want to change the position, then the knight MT will automatically achieve the fake MT gear change. . <Variation 1 > In the above embodiment, the downsizing operation in which the + down in the MT downshift mode is performed after the operation of the mode temporary change switch 43 is entered into 128766.doc -32- An example of 200848637. However, as shown in FIG. 14, thousands, & ', further downshifting operations may be performed after the operation of the kanako downshift switch 42 and the mode may temporarily change the switch in the mode in the MT downshift mode. "After the operation, return to the AT mode. <Modification 2> In the above embodiment, it is explained that /, A. The temporary change switch 43 is independent and the pull type is operated and gripped. Bucket, | Shi Ping f ° Hai nuclear type temporarily changes the switch 43 to change to the MT drop mode. 钬, ..., and, the present invention is not limited to this configuration. In this variation 2, the tether system In the case where the mode temporarily changes the switch 4 3 and is not independently set, the system changes to one of the examples of the downshift mode after operating the downshift switch 42. Additionally, in explaining this change In the case of the servant, the same as in the previous embodiment, reference is made to Fig. 1. In addition, the έ, 、, 、, 、, and the parts are denoted by the same reference numerals and/or symbols and will not be described again. Summary of one of the manipulation handles 4 of this μ type 2 Here, the switch box 4〇a in the variant 2 does not have the mode temporary change switch 43. The left side of the switcher ^λ β ] off i 40a only has the upshift switch 41 and the downshift The switch 42. The number of switches that are placed in the left portion of the switch box 4 〇a is small, so the upshift switch 41 and the downshift switch 42 are disposed in the above embodiment. In addition, the setting position of the mode selection switch 44 is not limited to the left grip portion b. For example, the _ type selection_4 is disposed in the left portion of the right grip portion 4b. In other words, a further switch box can be disposed in the left portion of the right grip portion 4b and the mode select switch 44 can be positioned in the other switch box 128768.doc -33-200848637. In this alternative, preferably, the mode selection switch 44 is positioned at a position where the index finger of the knight's right hand can operate the switch 44. As shown in FIG. 16, in this variation 2, The downshift signal output when the downshift switch 42 is operated in the AT mode丨6 is the mode change signal 101. That is, as shown in FIG. 17, when the knight operates the downshift switch 42 in one of the eight-but mode S1(b), the one is used as the mode change signal 101. The gear signal 1〇6 is output to the ECU 5. When the downshift signal 106 is input to the ECu 5, the Mτ downshift mode is selected by the centring mode temporary selection portion 51. With this - selection The gear ratio of the transmission (9) is changed by the gear ratio control portion 55 to a predetermined plurality of gear ratios (first speed to fifth speed) existing below the shift (four): a current gear ratio - One of the gear ratios in the low value range. In this variation 2, when the down converter switch 42 is operated in the MT downshift mode, the downshift operation can be achieved (step S2(b)). "Action Mode and Efficacy">

Since the number of such operating switches is reduced, the number of switches is small. <Variation 3&gt; 1 and proceeding in the MT downshift mode There is no need to set the mode to temporarily change the switch 43 so that the upshift switch 41 and the downshift switch 42' can enhance the operability of the knight. Furthermore, less, the knight can operate the 128766.doc-34-200848637 more easily. In the above embodiment, the switch box 4 in which the mode selection switch 44 is placed in the left grip portion 4a is illustrated. An example in 〇a. However, the mode selection switch 44 is not limited to being placed in the left grip portion ^. For example, 'as shown in Fig. 18', the mode selection switch 44 can be placed in the left portion of the right grip portion 4b. More specifically, another switch box can be placed in the left portion of the right grip portion 4b and the mode selection switch can be positioned in the other switch box. As shown in Fig. 18, preferably, the mode Ο selection switch 44 is positioned at a position where the knight can operate the switch with the index finger of his right hand. &lt;Other Variations&gt; = The above-described example shows an example in which the belt type (4) is used as the electronically controlled transmission. The bran ..., the electronically controlled transmission can be different from the belt type ECVT. For example, the electronically controlled transmission can be a super-annular ECVT. In the above embodiment, the present invention is a case in which the speed-up motor type soap 1 is merely exemplified. However, the straddle type vehicle according to the present invention can be used in the motorcycle locomotive 'small locomotive, the more = the moto car, the so-called motorcycle ATV (the whole place, the straddle type) The vehicle can be a (Wang terrain vehicle) or the like. In the above embodiment, the lift switch 4 is lowered to off 42 a different operation switch, such as the mode selection switch 44, which is temporarily changed by the type 43. In this case, however, it is expected that the various types of so-called (four) correlations can be formed by the push rods. The sweat is used to rotate the switch, and the knob is 128766.doc -35- 200848637 moves between a plurality of positions. In the above embodiment, the gear ratio of the transmission 20 is changed by the gear ratio control portion 55 to a current gear ratio closer to the transmission 2 and exists An example of a gear ratio in a low value range of the predetermined plurality of gear ratios (the first speed to the fifth speed) that is lower than a current gear ratio of the transmission 20. However, the present invention is not limited The example. For example 'by the gear The control portion 55, the gear ratio of the transmission 2 can be changed to a gear ratio which is a predetermined plurality of gear ratios that are lower than the current gear ratio of the transmission 20 in a low value range (first The gear ratio of the current gear ratio closest to the transmission 2〇 of the speed to the fifth speed is closer to the current gear ratio of the transmission 20. More specifically, by the gear ratio control portion 55, The gear ratio of the transmission 20 can be varied to a gear ratio that is less than a predetermined plurality of gear ratios that are present in the low range compared to the current gear ratio of the transmission 20 (first speed to five The gear ratio of the current gear ratio closest to the transmission 2 is closer to the current gear ratio of the transmission 20 in the first stage. Further, the gear ratio of the transmission 20 is controlled by the gear ratio control portion 55. The ratio can be changed to a gear ratio that is less than a predetermined plurality of gear ratios (first speed to fifth speed) that are present in the low value range that are lower than the current gear ratio of the transmission 20 The most connected The gear ratio of the current gear ratio of the transmission 2 is closer to the current gear ratio of the transmission 2 in two stages or more. Alternatively, the knight can set the downshift amount. For example, if the knight wants to cause a faster speed Drive, the knight can choose a mode with a large downshift. 128766.doc -36- 200848637 If the knight wants to produce a slower mode of smaller downshifts, then the second (4) knight can choose - have A plurality of modes may be provided to temporarily change the switch 43. For example, a mode temporary change switch 43 having a smaller downshift amount and a larger downshift amount y々 tearing &lt; another 暂时 type temporary change switch 43 may be provided. In the embodiment, an example in which the motor η controlled in a PWM manner is used as an actuator for changing the gear ratio of the transmission 20 will be explained below. However, in the present invention φ,,,, the ratio of the gear ratio of the transmission 20 is changed.

Actuating the scorpion 5L is not limited. For example, the (four) device for changing the gear ratio of the transmission can be an electric motor controlled by 1 PAM (pulse amplitude modulation). Further, the actuator for changing the gear ratio of the transmission 2G may be a stepping motor. Further, the actuator for changing the gear ratio of the transmission 20 may be a hydraulic actuator or the like. In the above embodiment, an example in which both the automatic play mode and the manual MT mode are selectable is described. However, it is possible to implement a setting in which the automatic MT mode and the manual mode are selectable. Furthermore, it is also possible to implement a setting in which neither the automatic play mode nor the manual MT mode is selectable. That is, a configuration can be implemented in which only the AT mode and the MT downshift mode are available without the mode selection switch 44. Further, a setting may be performed in which a gear changing mode other than the Ατ mode, the automatic MT mode, the manual MT mode, and the fiscal downshift mode are selectable. In the above embodiment, an example in which the mode is changed to the manual MT mode in the 降τ downshift mode is explained. However, the mode can be changed to the automatic MT mode in the &quot;downshift mode. That is, a set of 128766.doc -37- can be implemented.

u 200848637, wherein the gear ratio of the transmission 20 can be automatically changed in accordance with the motorcycle R travel state after the mode is changed to the drop tank mode without the need for the knight to operate the operational switches. In the above-described embodiment, an example in which the gear change mode is sequentially changed whenever the single-mode selection switch 44 is operated is explained. For example, the mode selection switch for selecting the eight-but mode, another mode selection switch for selecting the automatic Μτ mode, and another one for describing the d-hai manual M-mode can be independently set. Mode selection switch. &lt;&lt;Embodiment 2&gt;&gt; Instead of the transmission 20 of the first embodiment, for example, as shown in Fig. 19, a transmission 260 having a - metal v-belt may be employed. In Fig. 19, members or portions that perform the same operation as the transmission of the embodiment shown in Fig. 4 are denoted by the same elements; However, in Fig. 19, the internal structure of 5 is the same as that of the first embodiment, and thus is not shown in the drawings. In the present embodiment, the transmission 260 has a plurality of repairs other than the v-belt 264 made of metal (hereinafter sometimes referred to as a metal band, as shown in Fig. 19).

The metal belt CVT 260 includes a clutch 35, 261, a primary rotary sensor, a hydraulic cylinder 267A, 267B, and a hydraulic control valve 267c. The clutch 35 is disposed between the output shaft 12 of the engine 10 and the input shaft 13 of the metal belt cvt 260. The clutch 35 engages or disengages the power transmission between the output shaft 12 of the engine 10 and the input shaft 13 of the metal belt CVT 26A. The clutch 35 of this embodiment is an electronically controlled multiple clutch. Therefore, the engagement or disengagement of the clutch 35 is electronically controlled automatically by 128766.doc -38-200848637. When the clutch 35 is engaged, the driving force of the engine 1 is transmitted to the main sheave 23 via the clutch 35. The driving force transmitted to the main sheave 23 is transmitted to the sub sheave 24 via the belt 264. The main rotational speed sensor 261 detects the rotational speed of the main sheave 23. The main rotational speed sensing sensor 261 outputs the rotational speed detected by the main sheave 23 to the ECU 5 as a sheave rotational speed signal 114.

The 忒 main groove 23 and the auxiliary sheave 24 respectively have a movable sheave half 23a and 24a and a fixed sheave half 23b, 24b. The movable sheave half 23b is constructed to be positioned in the axial direction of the input shaft 13 of the metal strip 260. The movable sheave half 24b is constructed to permit movement in the axial direction of the output shaft 14 of the metal strip CVT 26〇. The main rotation sensor 261 detects the rotational speed of the main sheave 23. In this embodiment, the ECU 5 is from the rotational speed of the main sheave 23 detected by the main rotational sensor 261 and the straddle detected by the vehicle speed sensor 32. The gear ratio of the metal belt CVT 260 is calculated as the ratio between the vehicle speeds of the type of vehicles. In detail, the gear ratio of the metal belt CVT 26 is calculated by the ECU 5 based on the ratio of the sheave rotational speed signal 丨丨 4 to the vehicle speed signal 112.
