Abstract

A vehicle anti-theft apparatus and method can prevent the theft of a vehicle and the illegal use thereof without increased costs. The apparatus includes an IC card carried by a user of a vehicle, an IC card reader in the vehicle for reading information contained in the IC card, and an authentication processing section in the vehicle for authenticating the user when the vehicle is used. The IC card includes a memory for storing identification information and use time limit information of the vehicle. The IC card reader reads the identification information and the use time limit information stored in the memory. When the identification information of the IC card and authentication identification information stored beforehand in the vehicle coincide with each other, and when a current time is within a use time limit of the use time limit information, the authentication processing section permits the use of the vehicle.

Claims

1. A vehicle anti-theft apparatus comprising:

an IC card that is carried by a user of a vehicle;

an IC card reader that is provided in the vehicle for reading information in the IC card; and

an authentication processing section that is provided in the vehicle for authenticating the user when the vehicle is used by the user;

wherein the IC card includes a storage section that stores identification information of the vehicle and use time limit information of the vehicle;

the IC card reader includes a reading section that reads the identification information and the use time limit information stored in the storage section; and

when the identification information and authentication identification information that is stored beforehand in the vehicle coincide with each other, and when a current time is within a use time limit of the use time limit information, the authentication processing section permits the use of the vehicle.

2. The vehicle anti-theft apparatus as set forth in claim 1, wherein

the authentication processing section includes:

an identification information determination section that determines whether the identification information and the authentication identification information coincide with each other; and

a use time limit information determination section that determines whether the current time is within the use time limit of the use time limit information.

3. The vehicle anti-theft apparatus as set forth in claim 1, wherein

the authentication processing section permits the starting of an engine of the vehicle.

4. The vehicle anti-theft apparatus as set forth in claim 1, wherein

the authentication processing section authenticates the user when the user tries to start an engine of the vehicle.

5. The vehicle anti-theft apparatus as set forth in claim 1, wherein

the current time is output from a timer device built into the vehicle.

6. The vehicle anti-theft apparatus as set forth in claim 1, wherein

the current time is output from a GPS device installed on the vehicle.

7. The vehicle anti-theft apparatus as set forth in claim 1, wherein

the identification information and the use time limit information are stored in the IC card in advance before the user carries the IC card.

8. A vehicle anti-theft method comprising the steps of:

storing, into an IC card that is carried by a user of a vehicle, identification information of the vehicle and use time limit information of the vehicle;

reading the identification information and the use time limit information stored in the IC card by means of an IC card reader installed on the vehicle; and

permitting the starting of an engine of the vehicle by means of authentication processing section provided on the vehicle when the identification information and authentication identification information that is stored beforehand in the vehicle coincide with each other, and when a current time is within a use time limit of the use time limit information.
