Patent ID: 7176788

Claim:
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.
