Each is electrically connected. The lock control means 3 can release the lock by the lock means 2 that regulates the traveling of the vehicle when the determination means 1 determines that the authentication code is a legitimate authentication code.

As shown in FIG. 2, the vehicle-mounted unit B according to the present embodiment includes a locking means 2 including a solenoid, a steering lock bar (not shown), and a rotor n1 that is rotated by a rotation operation of an operation knob N. It is composed of. Then, when the operation knob N is rotated to the ON position, the rotor n1 follows and rotates, so that the main switch including the ignition switch that enables the engine to be started is turned on and the engine of the vehicle can be started. ..

The steering lock bar is a lock position that is inserted into a lock hole (not shown) formed in the handlebar of the vehicle to lock the handlebar, and an unlock position that retracts from the lock hole to unlock the handlebar. It is said that it can be moved between and. Then, when the operation knob N is rotated to the LOCK position, the cam member rotates together with the rotor n1 so that the steering lock bar can be moved between the lock position and the unlock position.

The locking means 2 regulates the traveling of the vehicle, and as shown in FIG. 2, is composed of a solenoid having a plunger 2a. The plunger 2a can move between a locking position (position shown in the figure) locked to the locking portion n2 formed on the rotor n1 and a non-locking position separated from the locking portion n2. It is possible to electrically connect to the battery b mounted on the vehicle by the control by the lock control means 3.

On operation can be regulated. That is, since the locking means 2 includes an ignition switch of the vehicle and an actuator for locking the operation of the steering lock, the engine of the vehicle can be started by releasing the lock by the locking means 2. It is possible to release the steering lock.

Therefore, when the engine is stopped, the rotation operation of the operation knob N is locked by the locking means 2, and the communication performed between the portable device A and the vehicle-mounted unit B is performed from the portable device A. When it is determined that the transmitted authentication code is a legitimate authentication code, the lock by the locking means 2 is released, and the rotation operation of the operation knob N is permitted, so that the engine of the vehicle can be started. ..

The energization circuit 11 can heat the gripping surface of the handle grip G by supplying electric power from the battery b to the heating means 8 to energize the heat generating portion 9 (see FIG. 5) made of a conductor (metal pattern). be. By energizing the heating means 8 by the energizing circuit 11, the heat generating portion 9 can be energized to generate heat. As shown in FIGS. 1 and 5, the energization circuit 11 according to the present embodiment is electrically connected to the switching circuit 10.

The electrostatic determination circuit 12 (detection means) is electrically connected to the heating means 8 via the switching circuit 10 and is in contact with or close to the heating means 8 (that is, with respect to the handle grip G). It is possible to detect the driver's gripping state). That is, since the heat generating portion 9 formed in the heating means 8 is made of a conductor whose capacitance changes when a part of the driver's body approaches, the handle grip G is operated in a state where the battery b does not energize. When a person grips the heat-generating portion 9 and the gripped hand approaches the heat-generating portion 9, the capacitance of the heat-generating portion 9 changes.

The electrostatic determination circuit 12 according to the present embodiment can detect that the driver has gripped the steering wheel grip G by detecting that the capacitance has changed in the heat generating portion 9 as described above. It is configured. That is, the electrostatic determination circuit 12 is a non-contact sensor (static electricity) that detects a part of the driver (hand to be gripped) from the change in capacitance generated between the part of the driver (hand to be gripped). It is configured to function as a capacitance sensor). As shown in FIGS. 1 and 5, the electrostatic determination circuit 12 according to the present embodiment is electrically connected to the switching circuit 10.

The switching circuit 10 can switch between a detection state in which the electrostatic determination circuit 12 (detection means) can detect contact or proximity of the driver and a heat generation state in which the heat generation unit 9 is energized to generate heat. It is possible to switch from "detection state" to "heat generation state" on condition that the engine has started, and to switch from "heat generation state" to "detection state" on condition that the engine of the vehicle has stopped. ..

The self-holding circuit 14 is switched when the vehicle engine is stopped for a predetermined time (that is, the electrostatic determination circuit 12 does not detect gripping of the handle grip G for a predetermined time after the engine is stopped). The power supply from the battery b to the circuit 10, the energization circuit 11, and the electrostatic determination circuit 12 is stopped, and the internal power source 13 such as a battery can be switched so that the electric power is supplied to the determination means 1. ..

The auxiliary switch 6 is composed of a switch provided in the vehicle, such as an engine starter switch for starting and operating the engine or a brake switch that is turned on by operating a brake lever, and has detected the operation of the engine starter switch or the brake switch. At this time, the determination means 1 is configured to make a determination regardless of whether or not the driver's contact or proximity is detected by the electrostatic determination circuit 12 (detection means).

Further, in the present embodiment, when the operation of the engine starter switch or the brake switch is detected while the power is supplied from the internal power supply 13 by the self-holding circuit 14, the power is switched from the battery b and the electrostatic determination circuit is used. It is configured so that the determination means 1 makes a determination regardless of whether or not the driver's contact or proximity is detected by the 12 (detection means).

Further, in the present embodiment, after the engine of the vehicle is started, the detection state is intermittently switched at a predetermined timing, and the presence or absence of the driver in the state where the engine is started can be detected. There is. That is, when the engine of the vehicle is started, the switching circuit 10 switches from the "detection state" by the electrostatic determination circuit 12 to the "heat generation state" by the heating means 8, and the grip surface of the handle grip G is heated and the grip surface thereof is heated. Even in the "heat generation state", the presence or absence of a running driver can be detected intermittently in the "detection state" at a predetermined timing.

Next, the control content of the vehicle wireless authentication system according to the present embodiment will be described with reference to the flowchart of FIG.
First, when the engine of the vehicle is stopped and is in the "detection state", it is determined in S1 whether or not the detection means (electrostatic determination circuit 12) has detected that the driver has gripped the steering wheel grip G. If it is not detected, the process proceeds to S2, the engine is stopped, the "detection state" by the detection means (electrostatic determination circuit 12) is started, and it is determined whether or not a predetermined time has elapsed.

When it is determined in S2 that the predetermined time has elapsed, the process proceeds to S3, the power supply from the battery b is stopped, and the power is turned off. When the power supply from the battery b is stopped, the power supply from the internal power supply 13 to the determination means 1 is maintained. Then, after the power supply from the battery b is stopped and the power is turned off, it is determined in S4 whether or not there is an operation of the engine starter switch or the brake switch which is the auxiliary switch 6, and if there is such an operation, S5. The signal related to the vehicle-specific authentication code is communicated with the portable device A to start the vehicle authentication.

On the other hand, if it is determined in S1 that the detection means (electrostatic determination circuit 12) has detected that the driver has gripped the steering wheel grip G, the process proceeds to S5 and the vehicle-specific authentication code is exchanged with the portable device A. The communication of the signal related to is performed. Therefore, it is not necessary to press the conventional access switch or the like, and the signal related to the vehicle-specific authentication code can be communicated with the portable device A, and the vehicle authentication can be started.

After that, the process proceeds to S6, and it is determined whether or not the vehicle authentication is normally completed, and it is determined that the authentication is normally completed (that is, the determination means 1 determines that the authentication code is a legitimate authentication code). , S7, and the lock control means 3 releases the lock by the lock means 2. Then, in S8, it was determined whether or not the start operation by the driver (in the present embodiment, the operation of turning on the engine starter switch after turning on the main switch) was performed, and it was determined that the start operation was performed. If so, proceed to S9 to start the vehicle engine.

Here, when the engine of the vehicle is started in S9, the switching circuit 10 switches from the "detection state" to the "heat generation state", and the heat generation portion 9 of the heating means 8 is energized, so that the handle grip G Warm the gripping surface of. That is, on condition that the engine is started, the switching circuit 10 can switch from the "detection state" to the "heat generation state". This makes it possible to heat the driver's hand holding the steering wheel grip G when the vehicle is traveling.

After the engine of the vehicle is started, the "heat generation state" may be intermittently switched to the "detection state" at a predetermined timing, and control may be performed so that the presence or absence of a driver in the state in which the engine is started can be detected. .. Then, in S11, it is determined whether or not the engine of the vehicle has stopped by the operation by the driver, and when it is determined that the engine has stopped, the switching circuit 10 switches from the "heat generation state" to the "detection state" in S12. Will be.

As a result, when the engine of the vehicle is stopped, it is set to the "detection state", and the electrostatic determination circuit 12 can detect the driver's grip on the steering wheel grip G. It is possible to communicate (authenticate) a signal related to the vehicle-specific authentication code with the machine A. As a result, the series of control is completed, and the process returns to S1 to perform the same control.

According to the above embodiment, the electrostatic determination circuit 12 (detection means) capable of detecting the contact state or proximity state of the driver to the heating means 8 is provided, and the contact state or proximity of the driver is provided by the electrostatic determination circuit 12. Since the determination means 1 makes a determination on condition that the state is detected, the operation by the access button is unnecessary and the operability at the time of authentication can be further improved. In particular, the heat generating portion 9 according to the present embodiment is made of a conductor whose capacitance changes when a part of the driver's body is close to the heat generating portion 9, and the detecting means is such that a part of the driver's body is attached to the heat generating portion 9. Since it is composed of an electrostatic determination circuit 12 that can detect that a change in capacitance has occurred in contact with or in close proximity, the configuration of the heating means 8 can be effectively used (diverted) to improve operability at the time of authentication. Can be done.

Further, the heating means 8 according to the present embodiment can detect the contact or proximity of the driver by the change in the capacitance of the heat generating unit 9 while the heat generating unit 9 is not energized, and the engine of the vehicle is started. Since the heating unit 9 can be heated by energizing the heat generating unit 9 on the condition that the heat generation unit 9 is heated, the detection of the driver's contact state or proximity state with the heating means 8 and the heating by the heating means 8 are performed at an appropriate timing. You can switch.

Further, according to the present embodiment, it is possible to switch between a detection state in which the electrostatic determination circuit 12 (detection means) can detect the contact or proximity of the driver and a heat generation state in which the heat generation unit 9 is energized to generate heat. The switching circuit 10 has a circuit 10, and the switching circuit 10 switches from the detection state to the heat generation state on the condition that the engine of the vehicle is started, and changes from the heat generation state to the detection state on the condition that the engine of the vehicle is stopped. Since the switching is performed, the detection state and the heat generation state can be switched at an appropriate timing by the switching circuit 10.

Further, the switching circuit 10 according to the present embodiment is supposed to intermittently switch to the detection state at a predetermined timing after the engine of the vehicle is started, and detects the presence or absence of a driver in the state where the engine is started. Therefore, it is possible to easily grasp the presence or absence of a driver after the engine is started. The switching circuit 10 may be in a heated state (without switching to an intermittent detection state) from the start of the vehicle engine to the time when the engine is stopped.

In addition, according to the present embodiment, when the operation of the engine starter switch or the brake switch (auxiliary switch 6 in the present embodiment) provided in the vehicle can be detected and the operation of the engine starter switch or the brake switch is detected. Since the determination means 1 is used to make a determination regardless of whether or not the driver's contact or proximity is detected by the electrostatic determination circuit 12, problems occur in the heating means 8 and the electrostatic determination circuit 12 (detection means). At that time, it can be authenticated by operating the engine starter switch or the brake switch.

Although the present embodiment has been described above, the present invention is not limited to this, and for example, the heating means 8 is not limited to the one arranged on the handle grip G, and the vehicle can be seated by the driver. It may be composed of a seat heater arranged on the seating seat of. As described above, if the heating means is arranged on the steering wheel grip G of the vehicle that the driver can grip or the seating seat of the vehicle that the driver can sit on, a general-purpose heating means is used ( It can be diverted) and authenticated.

Further, the locking means 2 according to the present embodiment is an actuator for locking the operation of the steering lock or the ignition switch of the vehicle, but even if it locks other operations for restricting the running of the vehicle. good. Further, although the vehicle-mounted unit B according to the present embodiment is provided with an ignition switch integrally, the ignition switch may be separately formed and provided at a separate position of the vehicle. Although the present embodiment is applied to motorcycles, it may be applied to other vehicles such as ATVs, snowmobiles, construction machines or agricultural machines, and automobiles.
