Research and application of CAN and LIN bus in automobile Network System

The communication principle of CAN (Controller Area Network) bus is introduced in detail. P87C591 is used as the microprocessor with CAN controller. The hardware and software of the high-speed and low-speed CAN bus networks are designed, in this paper, full active suspension control, engine control, airbag control, ASR/ABS/ESP control, traction control and transmission control are designed as high-speed CAN bus network and air-conditioning control, instrument control, wiper control, lighting control, window control and door control are designed as low-speed CAN bus network. The software of body network control node is designed. Data share is fully realized in network communication of body net work control system.
