Abstract

A vehicle anti-thief device includes an on-vehicle main unit, an on-vehicle bluetooth module, and a bluetooth mobile terminal to be carried by the user. When the user leaved the car, the on-vehicle bluetooth module receives no signal from the bluetooth mobile terminal and then drives the on-vehicle main unit into alarm mode. When the user with the bluetooth mobile terminal entered the communication radius of the bluetooth module, the bluetooth mobile terminal connects the on-vehicle bluetooth module wirelessly and gives a disarm signal to disarm alarm setting of the on-vehicle main unit.

Claims

1. A vehicle anti-thief device comprising:

an on-vehicle main unit installed in a car;

at least one sensor mounted in at least one corresponding location of the car on-vehicle main unit and electrically connected to said on-vehicle main unit and adapted to detect an abnormality of the respective corresponding location of said car and to send a corresponding abnormality signal to said on-vehicle main unit;

at least one alarm device mounted in the car on-vehicle main unit and electrically connected to said on-vehicle main unit and controlled to output a corresponding alarm upon said on-vehicle main unit in receipt of said corresponding abnormality signal from one said sensor on-vehicle main unit;

an on-vehicle bluetooth module mounted in the car on-vehicle main unit and electrically connected to said on-vehicle main unit and adapted to actively detect the presence of an external bluetooth module within the communication radius thereof and to make a code recognition with the detected external bluetooth module and then to communicate with said external bluetooth module after success of said code recognition, the communication radius of said on-vehicle bluetooth module extending to an external geo-zone from the body of said car;

a bluetooth mobile terminal adapted to actively detect the presence of a bluetooth module within the communication radius thereof and to make a code recognition with the detected external bluetooth module and then to communicate with the detected bluetooth module after success of said code recognition;

wherein when the bluetooth mobile terminal anti-thief is connected to said on-vehicle bluetooth module after success of a code recognition, the on-vehicle bluetooth module anti-thief sends a disarm signal to said on-vehicle main unit to disable the alarm setting of said on-vehicle main unit.

2. The vehicle anti-thief device as claimed in claim 1, further comprising an in-car device for enabling the user to input a confirmative signal into said on-vehicle main unit to confirm the alarm setting of said on-vehicle main unit is really desired to be disabled, and a timer adapted to drive said on-vehicle main unit to re-start alarm setting when said on-vehicle main unit receives no confirmative signal from said in-car confirmative device within a predetermined time interval.

3. The vehicle anti-thief device as claimed in claim 2, wherein said in-car confirmative device is a push-button mounted inside the car in which said on-vehicle main unit is installed.

4. The vehicle anti-thief device as claimed in claim 1, wherein said bluetooth mobile terminal is a bluetooth mobile phone.

5. The vehicle anti-thief device as claimed in claim 1, wherein said at least one alarm device comprises a siren.

6. The vehicle anti-thief device as claimed in claim 1, wherein said at least one alarm device comprises a wireless communication device connectable to a communication address assigned by the user of said car wirelessly.

7. The vehicle anti-thief device as claimed in claim 6, wherein said wireless communication device is a GPRS mobile telephone.

8. The vehicle anti-thief device as claimed in claim 6, wherein said communication address is a mobile telephone number.

9. The vehicle anti-thief device as claimed in claim 6, wherein said alarm is a short message.

10. The vehicle anti-thief device as claimed in claim 1, wherein said on-vehicle main unit unlocks the central door lock of the car upon receiving said disarm signal.
