In FIG. 1, 1 is a portable driver's card (IC card), and 2 is a controller such as a microcomputer provided in the vehicle.

In the driver's card 1, a security code (unique signal) and a fingerprint of a user (driver) are registered in advance as security information, a telephone number and mail memory, and a user's driving restriction (diabetes and the like). )
Personal information such as an alarm (operating area, time) according to the information is registered. Further, credit information may be registered to have a credit card function.

The controller 2 includes an antenna 3 provided in the vehicle for receiving the password of the driver's card 1 and a card light and light similarly provided near the driver's seat of the vehicle and into which the driver's card 1 is inserted. A lead device 4, a fingerprint matching device 5 provided near the driver's seat of the vehicle and matching the fingerprint of a specific user registered in the driver's card 1 with the actual driver's fingerprint, and Signals from the provided seating sensor 6 and a seatbelt wearing sensor 7 also provided near the driver's seat of the vehicle are input.

Based on the input signals, the controller 2 controls an engine switch 8 provided in the vicinity of the driver's seat of the vehicle, a vehicle equipment control unit 9 and a personal equipment control unit 10 to be described later, Control signals are output to a door lock actuator 11 provided on the door of the seat.

In the vehicle equipment control section 9, the vehicle condition such as selection of a multimeter, seat and mirror position, power steering and AT mode, inter-vehicle distance setting, radio channel, navigation, information memory, etc. is optimized according to a specific user. Is controlled so that

In the personal equipment control unit 10, via a navigation device or the like provided near the driver's seat of the vehicle,
The vehicle is controlled to a state corresponding to personal information such as a telephone number and mail memory and an alarm (driving area, time) according to a user's driving restriction (diabetes etc.).

Next, the control operation of the controller 2 will be described with reference to the flowchart of FIG.

First, after the initial settings are made in step P1, it is determined in step P2 whether the personal identification number of the driver's card 1 has been received via the antenna 3.
Here, the process is repeated until the reception is performed. If the reception is performed, the door lock is released via the door lock actuator 11 in step P3. That is, the driver can get on the vehicle. If the driver leaves the vehicle without getting into the vehicle, the reception is interrupted and the door is locked.

Next, in step P4, it is determined via the seating sensor 6 whether or not the driver is seated in the driver's seat. Here, the processing is repeated until the user sits down.
Then, the fingerprint collation device 5 stands by, and voice guidance such as "Please collate the fingerprint" and this kind of display are made.

Next, in step P6, it is determined whether or not the fingerprint collation is OK (matched). Here, the processing is repeated until they match, and when they match, in step P7, the vehicle equipment control unit 9
Then, the personal equipment control unit 10 operates, and the vehicle state recorded (registered) on the driver's card 1 and the vehicle state according to the personal information are set as described above.

Next, in step P8, it is determined via a timer or the like whether or not the seat position is OK (proper). Here, the process is repeated until the status is OK. When the status is OK, the engine switch 8 becomes operable (start permission state) in step P9, and voice guidance such as "Please start with the engine switch" and this kind of display are performed. You.

Next, in step P10, it is determined via the seat belt attachment sensor 7 whether or not the seat belt is OK (is attached). In other words, the shift lever cannot move from the N range or the P range without wearing the seat belt. Here, it is repeated until it becomes OK.
Is reached, the door is locked via the door lock actuator 11 in step P11. That is, the vehicle can run. When the engine is stopped after traveling, only the engine switch 8 is used.

As described above, in this embodiment, even if the driver's card 1 is stolen, if the fingerprint collation does not match, the operation of the engine switch 8 becomes impossible and the vehicle cannot run, so that the vehicle is stolen. It will not be done.
In addition, since it is not necessary to previously register the fingerprint of the specific user in the fingerprint collation device 5 provided in the vehicle, the versatility of the vehicle is enhanced. In addition, by storing personal information such as a telephone number and a mail memory in the driver's card 1, convenience is enhanced.

In the above-described main control operation,
The control operation of interrupt 01 shown in the flowchart of FIG.
The control operation of the interrupt 02 shown in the flowchart of FIG.

That is, in the control operation of the interrupt 01, it is first determined in step P12 whether or not the driver's card 1 has been received (after the card has been received). In step P13, it is determined whether the vehicle speed is zero via a vehicle speed sensor or the like. Next, if the vehicle speed is zero in step P13, the engine switch 8 becomes inoperable in step P14, the engine is stopped, and voice guidance such as "cannot receive a card" and this kind of display are made.

If the vehicle speed is not zero in step P13, voice guidance such as "Card cannot be received" and this kind of display are made in step P15. If the driver's card 1 has been received in step P12, it is determined in step P16 through the seating sensor 6 whether or not there is seating. Here, if there is a seat, the process ends,
If not, the engine switch 8 becomes inoperable in step P17, and voice guidance such as "Please get in the driver's seat" and this kind of display are made.

In this way, for example, when the driver leaves the seat after the vehicle equipment control unit 9 and the personal equipment control unit 10 in step P7 are operated, the engine switch 8 becomes inoperable, and the driver's operation is stopped. Changes cannot be made. This prevents the vehicle from being stolen when inadvertently leaving the driver's seat, thereby enhancing the security function.

In the control operation of the interrupt 02, it is first determined in step P18 whether or not the driver's card 1 has been received (after the card has been received). In Step P19, it is determined whether or not the user is sitting. Next, if it is not seated in Step P19, the door lock actuator 11
The door is locked through.

If there is a card reception in the step P18, the process is terminated as it is. If the user is seated in the step P19, voice guidance such as "cannot receive a card" and a display of this kind are performed in a step P21.

Thus, when the driver gets off the vehicle, the door is automatically locked via the door lock actuator 11.

The present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
