Electronic anti-theft system for vehicle components

摘要

An electronic anti-theft system (50) utilizes CAN bus (30) for authorizing vehicle components. The electronic anti-theft system (50) includes a central authorization module (10) storing at least one first identifier code, at least one electronic functional module (20A-20H) and a CAN bus (30). Each of the electronic functional modules (20A-20H) includes a vehicle electrical system identifier (VESI) device (22A-22H), which stores a second identifier code. The VESI device (22A-22H) 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 (10) activates the electronic functional module (20A-20H) for normal operation when receiving the acknowledgement signal from the VESI device (22A-22H) for the electronic functional module (20A-20H). The electronic functional module (20A-20H) 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 (50) of the present invention.
