Abstract:

CAN control network protocol is employed in most automotive body electronic control systems,but the need data transfer rate of automotive mirror control is very low,and the use of CAN bus communication has higher cost.LIN bus is an auxiliary bus network,which is low in cost and able to achieve the data communication with only one wire.The design of the network based on LIN bus can achieve the control on the left and right rear-view mirror of the bus.And the low power consumption and fault self-diagnosis function is designed to reduce the late maintenance costs,providing a viable solution for practical application.

Key words: LIN bus;bus network design;electric mirrors;fault diagnosis
