JP 2004-314806 A JP 2010-095016 A

  However, the vehicle start systems described in Patent Documents 1 and 2 require a plurality of indoor transmitters that transmit request signals for determining whether or not there is a portable device in the vehicle interior. However, the vehicle mounting property was not always good. In addition, since an engine switch for starting the engine is provided in the vehicle, for example, when the portable device is left in the passenger compartment, another person can easily start the engine. In addition, it is necessary to perform an unusual operation (an operation other than simply wearing the portable device), such as holding the portable device over the engine switch and performing trapon matching only when the battery of the portable device has run out. In some cases, the user may be confused about the operation method.

  The present invention has been made to cope with the above problems, and an object of the present invention is to provide a vehicle start system that is excellent in safety, easy to use, and can be configured at low cost.

Means for Solving the Problems and Effects of the Invention

In order to achieve the above object, a vehicle start system according to the present invention includes a portable device incorporating a transponder capable of wirelessly transmitting an ID code, and a coil antenna that is mounted on the vehicle and transmits a driving radio wave for driving the transponder. A transponder transceiver capable of wirelessly receiving an ID code wirelessly transmitted by a portable device, and a collating means for collating the ID code from the portable device with a pre-registered master code,
The portable device is provided with a push-type operation switch for starting / stopping the engine or turning the power on / off, and the vehicle receives the driving radio wave transmitted from the transponder transceiver by the transponder of the portable device. So that a slot allowing insertion of the portable device at a position close to the coil antenna is provided,
When the portable device is inserted into the slot and the operation switch of the portable device is in the push state, the ID code and the power switch state are wirelessly transmitted from the portable device to the transponder transceiver in response to the drive radio wave from the coil antenna. The engine can be started or the power can be turned on under the condition that the ID code is accepted and authenticated by the verification means. In this case, for example, when the portable device is inserted into the slot, the operation switch is exposed to the outside of the slot, the portable device is inserted into the slot, the operation switch is pushed, and verification is performed. When the ID code is received and authenticated by the means, the engine can be started or the power can be turned on. Note that “on” of the power supply means that the power supply position is ACC and IG on. For example, every time the operation switch is operated, off, ACC, and IG on are switched in this order. be able to.

  In the vehicle starting system of the present invention, an ID code is wirelessly transmitted from a transponder of a portable device to a transponder transmitter / receiver on the vehicle side, and collation between the ID code and a master code registered in advance is performed. (Trapone verification). This eliminates the need for a plurality of indoor transmitters that transmit request signals for determining whether or not there is a portable device in the vehicle interior, thereby reducing the cost of the starter system and improving vehicle mountability. Can be achieved. The portable device is provided with a push-type operation switch for starting / stopping the engine or turning on / off the power. As a result, as long as the user carries the portable device, other people cannot operate the operation switch at all, and thus safety can be improved. Further, even when the battery of the portable device is exhausted, the engine can be started / stopped or the power can be turned on / off by inserting the portable device into the slot and pushing the operation switch in the same manner as in normal operation. Therefore, it is possible to eliminate the possibility of the user being confused about the operation method.

  When the operation switch is exposed to the outside of the slot while the portable device is inserted into the slot, the portable device can be easily removed from the slot by picking the exposed part with a finger. become able to.

In addition, when the portable device is inserted into the slot, the operation switch is housed in the slot, and when the portable device is inserted, the operation switch is pushed by contact with the cover of the slot. When the portable device is inserted into the slot, the ID code verification is started by the verification means according to the push operation of the operation switch, and the engine is started when the ID code is accepted and authenticated. Can do. Furthermore, when the portable device is inserted into the slot without depressing the brake pedal of the vehicle, ID code verification is started by the verification means in accordance with the push operation of the operation switch, and ID code acceptance authentication is performed The power supply can be turned on.
In addition, triggered by the opening / closing of the driver's seat door or the depression of the vehicle's brake pedal, it is detected that the portable device is inserted into the slot by periodically transmitting radio waves from the vehicle's coil antenna. The engine can be started. Furthermore, the power supply may be turned on when the portable device is inserted into the slot without stepping on the brake pedal of the vehicle and the ID code is accepted.

  According to this, only by inserting the portable device into the slot, the operation switch is brought into a push state by contact with the cover portion of the slot. For this reason, the operation for starting the engine or turning on the power becomes simple, and the usability of the portable device can be improved. In addition, by detecting the inserted state of the portable device when the portable device changes from the state not inserted into the slot to the inserted state, the operation can be performed without operating the operation switch of the portable device. A configuration in which processing similar to that performed when the switch is operated may be performed.

  In addition, the slot may be provided with a portable device lock mechanism that can be switched between a lock release state that allows removal of the portable device and a lock state that prevents removal of the portable device. it can. In this case, for example, the portable device lock mechanism is one of the timing when the portable device is inserted into the slot and the ID code is accepted and verified by the verification unit, the timing when the engine is started, and the timing when the power is turned on. It is preferable to switch from the unlocked state to the locked state at this timing.

  According to this, for example, while the vehicle is running, the portable device can be prevented from being removed from the slot, and the engine is unexpectedly stopped due to the portable device falling out of the slot or being accidentally pulled out. Alternatively, it is possible to avoid a situation where the power is turned off.

  In this case, when the portable device locking mechanism is switched from the locked state to the unlocked state while the vehicle is stopped, and the portable device is pulled out from the slot in the unlocked state, the engine is stopped or the power is turned off. It can be set as a structure. The “stop state of the vehicle” is most preferably a state in which the shift position is switched to the “P” (parking) range, but is not limited to this. For example, when the vehicle speed is zero, the brake pedal is It can include a wide range of times when it is depressed. As these basic operations, a configuration is adopted in which the power is turned off when the operation switch is pushed while the vehicle is stopped (shift position is in the “P” range), and the operating engine is stopped. it can.

  According to this, the operation for stopping the engine or turning off the power becomes simpler, and the usability of the portable device can be improved.

  In addition, the portable device is provided with a door lock switch that switches the door to a locked state by wireless communication with the door control unit of the vehicle, and a door unlock switch that switches to the unlocked state, and the portable device is inserted into the slot. In this state, the door lock switch and the door unlock switch may be configured to be shielded from the outside by the slot.

  According to this, in a state where the portable device is inserted into the slot, it is possible to favorably avoid a situation in which the door lock switch or the door unlock switch is erroneously operated.

  In addition, it is preferable that the slot is set so that the cross-sectional area of the slot becomes smaller as the cross-sectional area of the opening serving as the insertion port of the portable device is maximized and the direction of insertion of the portable device is increased. According to this, since the portable device can be easily inserted into the slot, the operability can be improved. The slot can be configured to have a through hole communicating with the outside on the bottom surface. According to this, since foreign matter such as water (water droplets) and dust that has entered the slot can be discharged well to the outside of the slot, the inside of the slot can be kept clean. Moreover, you may make it provide the extrusion mechanism which pushes the portable machine inserted in the slot toward the exterior of a slot. According to this, the portable device can be easily taken out from the slot.

  In addition, an indicator or illumination that allows the user to visually recognize the position of the portable device or the operation switch of the portable device by lighting is arranged around the opening of the slot or the inserted portable device. it can. In this case, it is preferable that the indicator or illumination is set so that the illumination color or lighting mode can be changed according to the vehicle state. For example, it lights in blue until the user gets into the vehicle and inserts the portable device into the slot, blinks blue until the portable device is removed after the engine is stopped (power is turned off), and there is an abnormality in the starting system. It is conceivable to adopt a configuration that flashes red when it occurs.

  According to this, the operability of the portable device at night can be remarkably improved, for example.

  In addition, the shape of the portable device may be such that the tip side inserted into the slot is an acute angle or streamlined tapered shape so that it can be easily inserted into the slot. When the door lock switch and the door unlock switch are provided in the portable device, each switch can be easily identified by changing the appearance of the color and shape of these switches and operation switches.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a state in which a portable device 2 constituting a vehicle start system 1 (see FIG. 4) of the present invention is inserted into a slot 4 of a vehicle 3, and FIG. FIG. 3 shows the slot 4. As shown in the block diagram of FIG. 4, the vehicle starting system 1 includes a transponder transceiver 30 on the vehicle 3 side, a microcomputer 40 (hereinafter simply referred to as a microcomputer 40), a storage device 50, and the like in addition to the portable device 2. It consists of The microcomputer 40 is connected to each control unit (control circuit) such as the engine control unit 60 and the door control unit 70 via the in-vehicle LAN 100 so as to communicate with each other.

  The transponder transceiver 30 is incorporated on the back side of the slot 4. The transponder transceiver 30 includes a coil antenna 31 that transmits a driving radio wave for driving the transponder 10 of the portable device 2, a main circuit unit 32 (driving radio wave generation circuit unit) configured by a microcomputer, and a transmission / reception circuit And a wireless communication circuit unit 33 (transmission / reception circuit unit) configured to include a known demodulation circuit. The main circuit unit 32 generates a magnetic field (for example, an electromagnetic wave in an LF (long wave) band) toward the outside of the transponder transceiver 30 via the coil antenna 31.

  When receiving the data (transponder signal) including the ID code from the portable device 2, the wireless communication circuit unit 33 demodulates the data and sends it to the main circuit unit 32. The main circuit unit 32 reads the ID code from the demodulated data and transmits it to the microcomputer 40.

  The microcomputer 40 (collation means) has a CPU, ROM, RAM, input / output unit (I / O) and the like as main components, and includes an ID code collation processing program (not shown) stored in the ROM or the like. Various processing programs are executed repeatedly. Specifically, the microcomputer 40 uses the ID code from the portable device 2 transmitted via the transponder transmitter / receiver 30 as a verification master code (master ID) unique to the vehicle stored in the storage device 50. It is determined whether or not the collation of both ID codes matches (acceptance authentication).

  A stop lamp SW41 is connected to the microcomputer 40 so that an ON signal is input to the microcomputer 40 when the user steps on the brake pedal, and an ACC relay 42 is output so that a drive signal from the microcomputer 40 is output. A power relay such as the IG relay 43 and a portable device locking mechanism 44 are connected. The ACC relay 42, the IG relay 43, and the portable device lock mechanism 44 will be described later.

  The portable device 2 (wireless portable key, electronic key) functions as a portable wireless device capable of transmitting data to and from the transponder transceiver 30, and is shown in FIGS. 2 (a) to 2 (c). As shown, the distal end side inserted into the slot 4 has a streamlined (or acute angle) tapered shape, and, for example, an antenna 13 for wireless communication is built in the distal end side (see FIG. 4). The portable device 2 includes a case body 2a, a lid body 2b, and a strap 2c.

  As shown in FIG. 4, the portable device 2 has a memory 11a for storing an ID code, a main circuit unit 11 configured by a microcomputer, and a wireless including a known modulation circuit. A transponder 10 including a communication circuit unit 12 (transmission circuit unit) is incorporated.

  When receiving the driving radio wave generated by the transponder transceiver 30, the transponder 10 causes the main circuit unit 11 to generate an induced current based on the law of electromagnetic induction. The main circuit unit 11 uses this induced current as electric energy (for example, charging / discharging by a power supply capacitor), and transmits data including an ID code stored in the memory 11a via the wireless communication circuit unit 12 to a transponder transceiver. 30.

  In this case, when the portable device 2 is inserted into the slot 4 (so that the distance between the two is within 10 cm, for example), the transponder 10 receives the driving radio wave generated by the transponder transceiver 30 and the main circuit unit 11 Transmits data including the ID code to the transponder transceiver 30.

  On the other hand, when the portable device 2 is extracted from the slot 4 (so that the distance between the two exceeds 10 cm, for example), the transponder 10 does not receive the driving radio wave generated by the transponder transceiver 30 and thereafter the main circuit unit 11 Does not transmit data including the ID code to the transponder transceiver 30.

  As shown in FIGS. 2A and 4, the portable device 2 is provided with a push SW 21, a door lock SW 22, and a door unlock SW 23. Each SW21-23 is arrange | positioned in a line in the state exposed from the cover body 2b. The push SW 21 (operation switch) transmits the ON signal to the microcomputer 40, and the microcomputer 40 can start the engine starting unit 61 via the engine control unit 60, or the ACC relay 42, the IG relay 43, etc. The power relay can be driven.

  The door lock SW 22 transmits the on signal to the microcomputer 40, and the microcomputer 40 switches the door lock mechanism 71 to the locked state via the door control unit 70. The door unlock SW 23 transmits the ON signal to the microcomputer 40, and the microcomputer 40 switches the door lock mechanism 71 to the unlocked state via the door control unit 70 in response to the ON signal.

  When the portable device 2 is inserted into the slot 4, only the push SW 21 is exposed to the outside of the slot 4, and the door lock SW 22 and the door unlock SW 23 are shielded from the outside by the slot 4. Yes.

  As shown in FIG. 3, the slot 4 includes a pocket-shaped cover portion 4 a that is provided on the instrument panel 3 a corresponding to the driver's seat and allows the portable device 2 to be inserted. The cover 4a has a maximum cross-sectional area of the opening 4b serving as an insertion port of the portable device 2 so that the cross-sectional area of the slot 4 (internal cross-sectional area) becomes smaller toward the insertion direction of the portable device 2. Is set. Thus, the specification is such that the portable device 2 can be easily inserted into the slot 4.

  An indicator 4c is disposed in the opening 4b. The indicator 4c is set to be turned on by the microcomputer 40 when, for example, the user gets into the vehicle 3 at night or the like (for example, when the door control unit 70 receives a door unlock control signal). Thereby, since the user can visually recognize the position of the opening 4b by lighting the indicator 4c, the insertion into the slot 4 of the portable device 2 becomes extremely easy.

  In addition to the coil antenna 31 of the transponder transceiver 30, a portable device lock mechanism 44 is provided on the back side of the instrument panel 3 a corresponding to the slot 4 (see FIG. 4). The portable machine locking mechanism 44 includes, for example, a plunger 44a (see FIG. 2B) and an electromagnetic solenoid 44b that drives the plunger 44a, and the plunger 44a is formed in the case body 2a in accordance with a drive signal from the microcomputer 40. The engagement hole 2d is engaged or disengaged.

  That is, when the plunger 44a is engaged with the engaging hole 2d, the locking state is prevented from being pulled out from the slot 4 of the portable device 2, and when the plunger 44a is detached from the engaging hole 2d, it is removed from the slot 4 of the portable device 2. It will be in the unlocked state where extraction is allowed. In addition to or instead of the engagement holes 2d, for example, engagement holes 2d ′ are formed on both side surfaces of the case body 2a (see the broken lines in FIG. 2B), and the engagement holes 2d ′ are engaged. -A detachable plunger may be provided.

  The portable device lock mechanism 44 is unlocked in accordance with the drive signal from the microcomputer 40 at the timing when the portable device 2 is inserted into the slot 4 and the microcomputer 40 accepts the ID code in accordance with the operation of the push SW 21. Switch from state to locked state. On the other hand, when the vehicle is stopped while the engine is operating and the shift position is further switched to the “P” range, the portable device locking mechanism 44 changes from the locked state to the unlocked state in accordance with the drive signal from the microcomputer 40. It can be switched.

  Note that the portable device locking mechanism 44 has a timing at which the engine starter 61 is started in accordance with the operation of the push SW 21 (a timing at which the engine is started) and a timing at which a power supply relay such as the ACC relay 41 and the IG relay 42 is driven ( It is also possible to adopt a configuration in which the lock release state is switched to the lock state in accordance with the drive signal from the microcomputer 40 at any timing of the timing when the power is turned on.

  Next, the operation of the first embodiment configured as described above will be described. A case where the power is turned on first will be described. When the user presses the door unlock SW 23 outside the vehicle, the door lock mechanism 71 in the locked state is unlocked and the vehicle 3 can be boarded. When the portable device 2 is inserted into the slot 4 and the push SW 21 is pressed without stepping on the brake, the push SW 21 transmits an ON signal to the microcomputer 40.

  When the microcomputer 40 starts collating the ID code and the ID code matches (acceptance authentication), the microcomputer 40 turns on the ACC relay 42 if the power position is off, and turns on the IG relay 43 if the power position is already ACC.

  Next, the case where the engine is started will be described. After getting on the vehicle 3, when the portable device 2 is inserted into the slot 4 and the push SW 21 is pushed while stepping on the brake, the push SW 21 and the stop lamp SW 41 transmit ON signals to the microcomputer 40, respectively.

  When the microcomputer 40 starts collating the ID code and the ID code matches (acceptance authentication), the ACC relay 42 is turned on, the IG relay 43 is turned on, and an engine start request signal is transmitted to the engine control unit 60. . The engine is started by the engine control unit 60 starting the engine starting unit 61.

  Next, a case where the engine is stopped will be described. When the vehicle is stopped during the operation of the engine and the shift position is switched to the “P” range and then the push SW 21 is pressed, the microcomputer 40 turns off the power position regardless of whether or not the brake pedal is operated. As a result, the engine is stopped. When the door lock SW22 is pushed after getting off the vehicle 3, the door lock mechanism 71 is locked and the door cannot be opened.

  In the first embodiment, the ID code is wirelessly transmitted from the transponder 10 of the portable device 2 to the transponder transmitter / receiver 30 on the vehicle 3 side, and the microcomputer 40 collates the ID code with a pre-registered master code. (Trapone verification). This eliminates the need for a plurality of indoor transmitters that transmit a request signal for determining whether or not the portable device 2 is present in the vehicle interior, thereby reducing the cost of the starter system and improving the vehicle mountability. Improvements can be made. Further, the portable device 2 is provided with a push SW 21 as an operation switch for starting the engine or turning on the power. As a result, as long as the user carries the portable device 2, another person cannot operate the push SW 21 at all, so that safety can be improved. Further, even when the battery of the portable device 2 is exhausted, the engine can be started or the power can be turned on by inserting the portable device 2 into the slot 4 and setting the push SW 21 in the push state in the same manner as in the normal operation. Therefore, it is possible to eliminate the possibility of the user being confused about the operation method.
