ELECTRONIC ANTI-THEFT SYSTEM FOR VEHICLE COMPONENTS
First Claim
1. An electronic anti-theft system utilizing controller-area networking (CAN) bus for authorizing vehicle components, comprising:
- a central authorization module comprising a first CAN unit and storing at least one first identifier code;
at least one electronic functional module, each comprising a vehicle electrical system identifier (VESI) device, the VESI device comprising a secure unit, a secure data storage electrically connected to the secure unit and a second CAN unit electrically connected to the secure unit, the secure data storage storing a second identifier code; and
a CAN BUS electrically connected between the first CAN unit and the second CAN unit,wherein the secure unit is configured to receive a first identifier code transmitted through the CAN BUS and compare the first identifier code with the second identifier code thereof,wherein the central authorization module activates a normal function of the electronic functional module when the first identifier code is matched with the second identifier code of the electronic functional module.

Abstract
An electronic anti-theft system utilizes CAN bus for authorizing vehicle components. The electronic anti-theft system includes a central authorization module storing at least one first identifier code, at least one electronic functional module and a CAN bus. Each of the electronic functional modules includes a vehicle electrical system identifier (VESI) device, which stores a second identifier code. The VESI device compares the second identifier code thereof with an associated first identifier code, and issues an acknowledgement signal when the comparison is matched. The central authorization module activates the electronic functional module for normal operation when receiving the acknowledgement signal from the VESI device for the electronic functional module. The electronic functional module includes vehicle crucial components such as trip computer module and infotainment module. Therefore, illegal removal or use of vehicle components can be prevented for the vehicle equipped with the electronic anti-theft system of the present invention.
