Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a constant speed cruise control device for a motorcycle.

Constant speed running devices are widely used in four-wheeled vehicles. First, a conventional example of a constant speed traveling device will be explained with reference to FIG.

During normal driving, a throttle 2 is opened and closed by an accelerator pedal 1 to control speed.

When the vehicle is traveling at 80 km/h and the set switch 3 is set, the speed of 80 km/h detected by the vehicle speed sensor 4 is
The vehicle speed in Km/h is stored in the controller 5.

Then, this stored vehicle speed (80 km/h) is compared with the vehicle speed detected later by the vehicle speed sensor 4, and if the vehicle speed drops below the stored vehicle speed, for example, when approaching an uphill slope, controller 5
The actuator 6 is then controlled to operate the throttle 2 in the opening direction via the link mechanism 7. In this way, even if the driver takes his foot off the accelerator pedal 1, the set vehicle speed of 80 km/h is maintained, allowing so-called constant speed driving.

When it is necessary to decelerate, the constant speed running is canceled by the cancel switch 8. The cancel switch 8 is comprised of a brake switch that is turned on when the brake is stepped on, a clutch switch that is turned on when the clutch is released, or a neutral switch provided in the transmission section in the case of an automatic vehicle. To make the vehicle run at a constant speed again after releasing the setting, press the accelerator pedal 1 to reach the desired vehicle speed, then set the set switch 3 again, or press the resume switch 9 to set the vehicle speed currently stored in the controller 5 (80 km/h). h) There are two methods of automatically setting the vehicle to run at a constant speed.

However, if such a constant speed cruise control device for four-wheeled vehicles is applied directly to motorcycles,
The accelerator grip meant that the vehicle could be driven even if the driver took his hands off the steering wheel, which posed a safety problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a constant speed cruising control device for a motorcycle that prevents the risk of taking one's hand off the accelerator grip for a long period of time.

In order to achieve the above object, the constant speed running control device for a motorcycle according to the present invention detects the vehicle speed with a vehicle speed sensor, compares it with a set speed value, and controls the actuator to perform constant speed running control and brake. In a constant speed driving control device for an automobile having a control circuit that cancels the control based on a cancel signal obtained from an operation, etc., an accelerator operation detection device that detects when a driver releases a hand from an accelerator, and the accelerator operation detection device an alarm generation device that generates an alarm for a certain period of time from when it is detected that the user's hand has been released; an accelerator operation restart detection circuit that detects that the accelerator operation has been resumed within a certain period of time after the generation of the alarm; When restart is detected by the operation restart detection circuit, constant speed driving control continues without interruption, and if restart of accelerator operation is not detected after a certain period of time, constant speed driving control is canceled and the cancel signal is sent. In addition to performing slower deceleration control than the deceleration control by
The vehicle is configured to include a control circuit that gives priority to the cancel signal over a signal from an accelerator operation restart detection circuit.

According to the above configuration, the object of the present invention can be completely achieved. Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like.

FIG. 2 is a diagram showing the overall configuration of an embodiment of the constant speed traveling device according to the present invention.

The rotational force of the accelerator grip 1 is transmitted to the throttle 2 via the link 7. A force F ₂ is required to open the throttle 2. Furthermore, the output of the actuator 6 operated by a signal from the controller 5 requires a force F ₁ to return the accelerator grip 1 in addition to a force F ₂ to open the throttle 2 via the link 7 .

FIG. 3 is a detailed view showing the first embodiment of the actuator section and the link section.

In the example shown in FIG. 3, the accelerator grip 1 is connected to one arm 71 of the link 7, and the accelerator grip 1 is always urged in the direction of returning the accelerator grip ₁ with a force F1. The actuator 6 is connected to the other arm 72 of the link 7, and is similarly urged by force _F3 in the direction of always returning to the original position.

The arm 73 of the link 7 is connected to the throttle valve 2, and the throttle valve 2 can be opened by either the accelerator grip 1 or the actuator 6. The throttle valve 2 is constantly biased in the closing direction by a force _F2 . Link 7's arm 7
1 includes an accelerator switch 11 which is closed when the hand is released from the accelerator grip 1 and returned with a force _F1 .
is provided.

FIG. 4 is a detailed view showing a second embodiment of the actuator section and the link section.

The example in FIG. 4 shows an example using a rotary actuator. A bent arm 62 is fixed to the output shaft 61 of the rotary actuator 6, and the shaft 61
Semicircular rotary plates 63 and 64 are rotatably provided at the tip of the holder. The bent arm 62 applies force in the clockwise direction in the figure.
F ₃ is energized and counterclockwise rotation causes
The rotating plates 63 and 64 are rotated. A line 2a connected to the throttle valve 2 from the upper side of the rotary plate 63
is connected and is energized with a force _F2 that returns the throttle valve 2 to its original position. The rotating plate 64 is connected to the shaft 61
Although it is rotatable relative to the arm 62, it is fixed to the arm 62, and is connected to the wire 1a connected to the accelerator grip 1 from below, and is biased clockwise by _F1 . The accelerator switch 11 is closed when the accelerator grip 1 is removed, the rotary plate 64 rotates with force _F1 , and the end of the bent arm 62 comes into contact with it.

Now, the line 1a is drawn by the accelerator grip 1, and the rotary plate 64 is rotated counterclockwise, so that the arm 62 to which the rotary plate 64 is fixed rotates the rotary plate 63 counterclockwise, and the line 2a is Pull in the direction of the arrow to open the throttle valve 2. When the accelerator grip 1 is released, the rotating plate 64 and the bent arm 62 return to their original positions due to the forces _F1 and _F3 , and the rotating plate 63 is returned to its original position due to the force _F2 .

By rotating the actuator 6 in the counterclockwise direction, the bent arm 62 rotates the rotary plate 63, and the throttle valve 2 can be opened by drawing the line 2a. When the actuator 6 is de-energized, it is urged back to its original position by the force _F3 , and the throttle valve 2 is also closed by the force _F2 .

FIG. 5 is a circuit diagram showing a first embodiment of the control circuit.

The configuration and operation of this circuit will be explained with reference to the operation diagram shown in FIG.

First, a case will be described in which the set switch 3 is used to set the travel speed and the cancel switch 8 is used to cancel constant speed travel.

When the set switch 3 is turned on at time T1 in FIG. 6, the controller 5 stores the output of the vehicle speed sensor 4 at that time and establishes a constant speed running state. Thereafter, the actuator 6 is driven so that this stored value and the output of the vehicle speed sensor 4 match.

When any switch constituting the cancel switch 8 is operated at time T2, the input terminal D of the controller 5 becomes an instantaneous low level (D in Fig. 6).
(change at time T2), the constant speed running control state is canceled, and the vehicle speed is lowered as shown in FIG. 6B.

Next, the accelerator operation after the constant speed running control state is established by the resume switch 9 will be explained.

When the resume switch 9 is activated at time T3, the input terminal E of the controller 5 becomes instantaneously at a low level, and control for maintaining the storage speed is resumed.

When the accelerator is returned at time T4 and the accelerator switch 11 shown in FIG. 5 is opened, the timer circuit 15
The capacitor Ct begins to be charged through the resistor Rt. A reference voltage is applied to the non-inverting input terminal of the comparator COMPt of the timer circuit 15, and the output of the comparator COMPt is at a low level at the beginning of T3. Therefore, when the accelerator switch 11 is turned off, the gate G1 of the alarm device 12 connected to this switch 11 and the output terminal of the comparator COMPt.
An output appears at 2 and the buzzer Bzz is driven. The timer circuit 15 inverts the output of the comparator COMPt when time t1 has elapsed since the accelerator switch ₁₁ is turned off, but the output does not change until time _t1 has elapsed.

Assume that at time T5, the accelerator is released and the accelerator switch 11 is turned on, and at this time _t1 hours have not yet elapsed from the aforementioned time T4. The charge in the capacitor Ct of the timer circuit is instantly discharged via the diode Dt, but the output of the comparator COMPt remains at a low level. Alarm device gate G12
One of the input terminals becomes low level when the accelerator switch 11 closes, so the buzzer Bzz
stops pronunciation. If the accelerator is released before the output of the timer circuit 15 changes in this way, the warning by the buzzer Bzz is stopped at that point, and the constant speed running control state is continued as it is.

When the accelerator switch 11 is turned off again at time T6, the buzzer Bzz starts sounding as described above. T ₁ hour has passed since this time T6
If the accelerator switch 11 is still off even after time 7 is reached, the output of the comparator COMPt of the timer circuit 15 is inverted and becomes high level.

At time T7, comparator COMPt of timer circuit 15
When the output of
is connected to the D input terminal of This differentiating circuit 13 differentiates the rising edge using a capacitor and a resistor, inverts it using a transistor Trl, and outputs a pulse having a pulse width t ₂ to the controller 5 . This pulse is shown in dashed lines in FIG. 6D. This pulse is equivalent to a signal from the cancel switch 8, and causes the controller 5 to cancel the constant speed running control state.

Next, the initiation of constant speed driving control by operating the accelerator switch will be described.

When the accelerator switch 11 is turned off at time T8, the output of the comparator COMPt of the timer circuit 15 returns to low level. As a result, a signal is applied to the set terminal S of the flip-flop FF of the flip-flop circuit 16, and the flip-flop circuit 1
An output appears at gate G16 of No.6. This output is differentiated by a differentiating circuit 14 and a pulse with a pulse width t ₃ is applied to the terminal E of the controller 5. This pulse acts equivalently to the signal from the resume switch 9, and the controller 5 enters the constant speed running control state as described at T3. The configuration of the differentiating circuit 14 is the same as that of the differentiating circuit 13 described above.

Next, a case will be described in which the cancel switch is operated before the accelerator switch is operated (turned off).

When the accelerator switch 11 is turned off at time T9, the buzzer Bzz starts sounding as described above.

At time T10, the comparator of timer circuit 15
When COMPt is inverted and becomes a high level, the constant speed running state is canceled by the differential pulse output of the differentiating circuit 13 as described above, and the buzzer Bzz stops.

When the cancel switch 8 is operated at time T11, the flip-flop FF is set and one input of the gate G16 connected to the output of the flip-flop FF becomes low level.

Even if the accelerator switch 11 is turned on at time T12, one input terminal of gate G16 remains at T11.
From the point in time, the G16 is at a low level and remains closed, the differentiating circuit 14 is not operated, and the controller 5 does not enter the constant speed running control state.

When the resume switch 9 is operated at time T13, the constant speed running control state is resumed.

FIG. 7 is a diagram showing a second embodiment of the constant speed running control circuit of the device according to the present invention.

In this embodiment, a microprocessor 80 executes various controls, and signals are input from the following switches and the vehicle speed sensor 4 via an interface 81. The set switch 3 is a signal input switch that stores the current vehicle speed as a constant travel control speed. The cancel switch 8 is a switch that inputs a signal for canceling constant speed driving control. The resume switch 9 is a switch that restarts constant speed driving control at the stored vehicle speed.

The accelerator switch 11 is a switch for inputting the relationship between the accelerator and the driver's hands.

This device can perform the same control as the circuit of the first embodiment already described.

When you release your hand from the accelerator, a warning sounds for a certain period of time, and then constant speed driving control is canceled. If you put your hand on the accelerator and turn the lever during or immediately after the alarm is issued, the vehicle will resume driving at a constant speed. If the cancel switch 8 is turned on in a state where the constant speed running control state is released, the above-mentioned return is not performed.

FIG. 8 shows a flowchart showing the operating procedure of this embodiment.

When the set switch 3 is turned on while the vehicle is running (101), the constant running speed has already been stored (102). In this state, if the cancel switch 8 is not on (103) and the accelerator switch 11 is on (104), no warning is generated (105) and constant speed driving control is performed.

In this state, unless the set switch 3 is pressed again, the already memorized speed is maintained (103), (104), (105), (106)...
Constant speed running control is performed in the routine (103).

When the set switch 3 is pressed, the speed is updated to the current speed (102), and travel control is performed at that speed.

When the accelerator switch 11 is turned off (104) during constant speed driving control, a warning is issued by a buzzer or the like (113). If the accelerator is released during this warning or within a certain time _t1 after the warning occurs (114), the constant speed driving routine described above is maintained. The alarm will turn off after a certain period of time. If the accelerator is not released and the accelerator switch 11 is off for a time exceeding _t1 (114), the alarm will be off (115), but a certain level of deceleration control will be performed. When the cancel switch 8 is turned on (103) while the vehicle is running at a constant speed, rapid deceleration control (112) is performed.

Even if the set switch 3 is not on (101), if the resume switch 9 has already been pressed once (109), constant speed driving control is performed at the previously stored speed.

As explained in detail above, according to the present invention,
When you take your hand off the accelerator grip, the warning sounds for a certain period of time, and then constant speed driving control is canceled.If you put your hand on the accelerator grip and turn the lever while the warning is occurring, the vehicle will enter the constant speed driving control state again. Therefore, the constant speed driving control state is not inadvertently entered, and safe constant speed driving control can be performed even in a motorcycle.

Note that the accelerator switch may not be mechanical, but may be a touch switch or the like to detect when the accelerator is released.
