Abstract
To simplify the wiring harness of automotive body control system, the functional requirements of automotive door locks, window lifters, rearview mirrors, trunk lock, and lights were analyzed, and an architecture of automotive body electronic control system was put forward based on CAN bus technology. The application layer protocol referring SAE J1939 protocol specification was defined. And the door lock system was modeled and simulated as an example by using CANoe. The simulation results show that the proposed architecture of automotive body electronic control system works well, and the reliability of automotive body control system can be improved and the automotive weight and cost can be reduced.
