DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle capable of starting an engine by confirming an ID using a wireless ID tag. The present invention relates to a device for preventing unauthorized driving of a vehicle for preventing an accident or the like from occurring.

[0002]

2. Description of the Related Art In a four-wheeled vehicle, a legitimate user having a wireless ID tag (transponder) simply approaches the vehicle without using a key or a remote controller.
The vehicle can be unlocked and the vehicle can be driven by driving the engine by starting the engine. By using the wireless ID tag, a passive entry system of the vehicle (active System that allows the vehicle to be put on and driven without any complicated operations)
Such devices have been conventionally developed for the convenience of using the vehicle and for preventing unauthorized use of the vehicle by unauthorized users.

[0003]

In the conventional passive entry system for a vehicle as described above, the entry is completed by making the vehicle confirm the ID using a wireless ID tag. After that, it is the same as the conventional system using keys and remote control, after getting on and starting the engine,
Anyone can drive the vehicle regardless of the ID.

[0004] For this reason, when a legitimate user starts the engine and the vehicle is away from the vehicle, the vehicle is runaway when another person gets on and off the vehicle, or an infant or the like in the vehicle accidentally starts the vehicle. Therefore, there is a problem that an accident caused by theft of the vehicle or an erroneous operation by another person cannot be reliably prevented.

An object of the present invention is to solve the above-mentioned problems. Specifically, in a vehicle in which an engine can be started by confirming an ID using a wireless ID tag, a legitimate user is required. It is an object of the present invention to reliably prevent a vehicle from being stolen by getting on and off, and to reliably prevent accidents caused by erroneous operation of another person, even if the user leaves the vehicle with the engine started. Is what you do.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a vehicle in which the engine can be started by confirming an ID by a wireless ID tag at a predetermined time after starting the engine. In this case, the ID is collated with the vehicle again, and if the ID is not confirmed at that time, the vehicle cannot be driven by the engine.

According to the above-described device for preventing unauthorized driving of a vehicle, when a driving operation of the vehicle is performed after the engine is started, whether the driving operation is performed by a legitimate user or a legitimate use is performed on the spot. If there is a driver, the vehicle can be driven by the already started engine by confirming the ID to the vehicle.

On the other hand, if the driving operation of the vehicle is performed by a person other than the authorized user, and there is no authorized user on the spot, even if the engine is started, the ID is assigned to the vehicle. At the time when is compared again, since the ID is not confirmed (the ID is different or there is no reply), the engine is stopped or does not run up and the vehicle cannot be driven by the engine. The vehicle cannot run.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an apparatus for preventing unauthorized driving of a vehicle according to an embodiment of the present invention.

FIG. 1 schematically shows an example of a motorcycle keyless system to which a motorcycle unauthorized running prevention apparatus according to an embodiment of the present invention is applied. Things.

In the motorcycle keyless system shown in FIG. 1, an authorized user carrying a transponder (wireless ID tag) 1 of a built-in wristband type or a portable card type approaches the motorcycle (for example, a starter button). When a predetermined operation such as pressing is performed, an interrogation radio wave is transmitted from the vehicle-side antenna 2, an ID radio wave is transmitted from the transponder 1 carried by the user, and the ID radio wave is received by the antenna 2. The ID from the transponder 1 is input to the control unit 3 of the vehicle and collated.

When the control unit 3 confirms that the ID is for a legitimate user, the electric circuit of the vehicle is turned on by an output signal from the control unit 3, and the starter system and the ignition When the system is energized, the electric steering lock 4 is automatically released, and the fact that the electric circuit is turned on is displayed by a sound, lighting of an indicator lamp, or the like.

After confirming such a display, when the starter button 5 is pressed, the engine is started, and the vehicle is ready to run. When the use of the vehicle is completed, the engine is stopped by pressing the stop button 6,
A lock prompt is displayed by a sound or an indicator light, and the lock can be locked by pressing the lock button 7 in accordance with the sound. Then, by turning the handle to the lock position,
The vehicle can be stopped with the steering lock 4 engaged.

In such a keyless system for a motorcycle, when a regular user starts the engine and then leaves the vehicle, unauthorized driving is prevented so that another person cannot drive the vehicle without permission. The following configuration is added as a device.

That is, a neutral switch 8 for detecting with respect to a control unit of the vehicle that the gear of the transmission has been shifted to a non-neutral shift.
Also, a throttle switch 9 for detecting that the throttle has been opened is connected as a means for detecting that the start operation of the vehicle has been performed, so as to output the detection result to the control unit 3.

On the other hand, the control unit 3 of the vehicle has a program (circuit) for collating the ID transmitted from the transponder 1 in response to the detection of the starting operation from the neutral switch 8 and the throttle switch 9. When the start operation is detected, the ID of the legitimate user is not confirmed (when there is no transmission from the transponder), the engine will not blow up even if the throttle is opened, An output signal from the control unit 3 controls an ignition system and an electric load system of the vehicle so that the engine may stall when the vehicle enters the vehicle, or both of them may occur.

According to the device for preventing unauthorized driving of the vehicle in the keyless system for a motorcycle according to the present embodiment as described above, while a legitimate user keeps the engine started in a state where the vehicle is separated from the vehicle, another person can enter the gap. Even if the engine is started even if the engine is started, the start operation of the vehicle is not performed unless the ID is confirmed by the control unit 3 of the vehicle even if the vehicle steals the vehicle and tries to escape, or if another person touches the vehicle without permission and performs an incorrect operation. Then, when the engine does not blow up, stalls, or both,
Since the vehicle cannot be run, it is possible to reliably prevent the vehicle from being escaping and being stolen.

In a motorcycle, there is no equivalent to a door of a four-wheeled vehicle, and a throttle grip and a shift pedal are exposed to the outside so that anyone can easily touch it. According to the device for preventing unauthorized driving of a vehicle, mischief and accidents of the motorcycle can be effectively prevented.

In the motorcycle keyless system having the above-described configuration for preventing unauthorized driving,
In the present embodiment, a configuration for preventing idling from being left is added in order to prevent the air from being polluted by the meaningless idling for a long time and to prevent noise from being given to the neighborhood.

That is, by using the neutral switch 8 as a detecting means and incorporating a program (circuit) for preventing idling from being left in the control unit 3, the transmission is kept in a neutral state for a predetermined time or more after the engine is started. If the user ID is not confirmed (there is no transmission from the transponder), the engine is stopped by controlling the ignition system and the electric load system of the vehicle with the output signal from the control unit 3. .

By doing so, even if the user leaves the vehicle idling, the engine is automatically stopped when the user has left the vehicle for a predetermined time or more. Therefore, useless idling can be prevented, and the resulting air pollution and noise can be prevented. It should be noted that the program for preventing the idling from being left unchecked due to the user's ID not being confirmed continuously for a predetermined time or more does not require the neutral detection.

Further, in the present embodiment, as a keyless system for a motorcycle, the lock (steering lock) 4 of the vehicle is an electric automatic lock, and the ID is verified by the transponder 1 without performing an active unlocking operation. Even though the lock is automatically released, the lock button 7 is further provided, so that the lock button 7 can be operated to select locking / unlocking.

That is, in a motorcycle, when a product is stored in a warehouse or sold at a store, the battery is not usually connected, and the vehicle is pushed by a human hand to move the vehicle. In addition, since the unlocking cannot be selected by the automatic lock, the locked vehicle is lifted and carried, which makes the vehicle difficult to move. On the other hand, the lock button 7 is provided as described above. By making it possible to select locking / unlocking irrespective of ID collation, it is possible to solve such a problem peculiar to the motorcycle at the distribution stage.

As described above, one embodiment of the apparatus for preventing unauthorized driving of a vehicle according to the present invention has been described. However, the present invention is not limited to the above-described embodiment. For example, as shown in the above-described embodiment. It is also possible to implement not only to collate the ID again at the time of the start operation of the vehicle, but also to collate the ID again after a certain time has elapsed from the start of the engine by the timer, In addition, it is also possible to implement by omitting the configuration for preventing idling from being left as described in the above-described embodiment and the lock button for enabling the selection of locking / unlocking. As for the application, the design can be changed as appropriate, for example, the invention is not limited to the motorcycle device as shown in the above embodiment, but can be applied to other vehicles such as a four-wheel vehicle. It is needless to say a thing.

[0025]

According to the apparatus for preventing unauthorized driving of a vehicle according to the present invention as described above, while an authorized user is away from the vehicle with the engine started, a device other than the authorized user is used. Even if the vehicle is started, the vehicle cannot continue to run. Therefore, it is possible to reliably prevent theft of the vehicle due to escape or accident due to erroneous operation by another person.
