Design Of Vehicle Door Control System Based On CAN

With the development of modern automobile technology, the number of electrical device on vehicle increases dramatically. The peer to peer connection makes wire harness complicated and difficult to repair. The bus-based automobile body control technology attracts wide concern and application.As door control system is very important part of automobile body control, it is directly connected with safety, comfort and convenience of passenger. This essay lay emphasis on research about CAN Bus-based door control system from Topu structure, hardware and software. The source of this essay is from automobile body design of Chery A0 Platform.Based on design need of automobile door control system, this essay explains the process of general proposal design, hardware design, and software design in details. It also depicts every module's hardware such as the central processor circuit, CAN Transceiver, anti-jamming CAN-communication circuit, electrical machinery drive control circuit. Also it points out the concept of software module design, the application layer protocol is set as required. It states main program of controller, open and close program of central control latch, subprogram of window regulator electromotor and the subprogram of rear mirror with left-front door controller unit as the example. And it illuminates program and software design of other controller units.In the end this essay designed a set of stimulation validation system, it use software to simulate the central controller of driver side to control the executor of latch, electrical window regulator and rear view mirror on front right door. The testing results shows that design of this essay can meet the design requirement...
