Title Application of CAN bus in Hybrid Electric Vehicle Control Unit
Abstract
This paper mainly introduces the application of CAN bus in the motor control unit of a series hybrid electric vehicle. CAN bus is a serial data communication bus, widely applied in the automotive industry, industrial control, engineering machinery, medical machinery and other field-bus systems. CAN bus has lots of advantages including high reliability, low cost and adequate functions. Series hybrid system is widely used in urban public transport system. The development of CAN bus in SHEV control unit has bright prospects and adequate technical supports. This paper designed a CAN module hardware circuit of SHEV motor unit and set forth the relevant principles; wrote the relevant initialization, transmission and reception program; put forward the corresponding anti-jamming measures.
