Design of Passenger Car Illumination and Signal Lamp Multiplexing Control System
HU Jian, LI Gangyan, WU Xiude, ZHOU Jianhua (School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan, China 430070.) Abstract: The author constructs passenger car illumination and signal lamp multiplexing control system based on CAN (Controller Area Network) and designs system structure, node parameters, correlative flow chart and hardware framework. The design of system node is according to the position and security of passenger car illumination and signal lamp. This paper uses the control
method of command control----status testing----status indication to realize passenger car lamp status automotive test and enhance passenger car‘s security.
