【Abstract】 Based on the DSP platform,the author designs a communication program for motor controller.In order to control and monitor the dynamic system and other subsystems of an electric vehicle(EV) effectively,the monitor system and EV CAN bus application layer protocol are developed.It is proved in the condition of lab that the monitor system can be used to communicate with other nodes of the car through the CAN bus so as to realize the on-line data monitoring and fault diagnosis.更多还原
