The acceptance and introduction of network communication to more and more applications in vehicle has led to requirements that the assignment of message identifiers to communication be standardized for certain application. This application can be realized with SAE J1939 more comfortably which based on CAN bus communication protocol. J1939 is a high speed, Class C type communications network designed to support real time closed loop control functions between electronic control devices, which may be physically distributed throughout the vehicle. J1939 uses the CAN protocol which permits any device to transmit a message on the network when the bus is idle. Every message includes an identifier which defines the message priority, who sent it, and what data is contained within ft. Collisions are avoided due to the arbitration process that occurs while the identifier is transmitted (using a non-destructive arbitration scheme). This permits high priority messages to get through with low latency (delay) times because there is equal access on the network for any device. SAE J1939 was designed to allow electronic devices from different vendors to communicate with each other through a standard architecture. In this paper, the SAE J1939 communication protocol has been implementation in electric vehicle with a CAN controller of Motorola DSP56F807, and established a CAN network protocol used on electric vehicle and put forward an implementation method. The identification bit of data for the vehicle controller is presented in accordance with J1939 protocol. The communication process for them is also given.
