Abstract
A vehicle theft prevention system and a method thereof. The system includes an Electronic Control Unit and a vehicle information terminal. The ECU is mounted with a controller that generates a vehicle motion detection message by receiving abnormal detection signals from various sensors detecting the orientation and location of the vehicle and outputs the message through a Control Area Network communication interface. A vehicle information terminal includes a Central Processing Unit, constant voltage circuit part, and CAN communication interface. The CPU is equipped with a Global Positioning System module and mobile communication module. The system thus constructed executes a vehicle motion informing function to prevent vehicle theft even when the vehicle ignition key is turned off.
Claims4
A vehicle theft prevention system comprising:
- an electronic control unit provided with a controller that generates a vehicle motion detection message by receiving abnormal detection signals from various sensors detecting the orientation and location of the vehicle and outputs the vehicle motion detection message through a control area network communication interface;
- and
- a vehicle information terminal including:
- a central processing unit equipped with a global positioning system module and a mobile communication module, said central processing system generating a vehicle motion informing message to be outputted through said mobile communication module, if the vehicle is determined to have traveled over a predetermined distance based on a global positioning system location information of said global positioning system module;
- a constant voltage circuit element that generates a driving power of said central positioning system by receiving a battery power supply;
- and
- a control area network communication interface that operates said central processing system by applying a driving signal into said constant voltage circuit element, if the vehicle motion detection message is received through a control area network communication while the vehicle ignition key is turned off.
A vehicle theft prevention method in a system including a global positioning system module, a mobile communication module, and a controller, which operates a vehicle motion informing function by using the global positioning system module and the mobile communication module during the detection of vehicle theft, comprising:
- an electronic control unit receives detection values from various sensors, which detect the orientation and location of the vehicle when the vehicle ignition key is turned off;
- the electronic control unit generates a vehicle motion detection message and transmits said message to the controller, if abnormal detection signals are detected from the various sensors;
- a communication interface receives the vehicle motion detection message transmitted from the electronic control unit;
- the communication interface operates the controller by a constant voltage circuit element that is applied with a driving signal and generates a driving power of the controller;
- the controller computes the traveling distance of the vehicle based on a global positioning system location information of the global positioning system module;
- and
- the controller generates a vehicle motion informing message and transmits the message through the mobile communication module, if the traveling distance of the vehicle exceeds a predetermined value.
