Because the electric motor, battery and other control units have to be used in hybrid system, data exchange between the control units is complicated. Traditional RS232 communication is hard to satisfy the requirements. In order to guarantee the reliability of data exchange, a kind of communication system based on SAEJ1939 is developed. It is consisted of software and hardware. The experimental results show that the system is of great reliability and is suitable for hybrid excavator. Keyword—SAE J1939, hybrid excavator, CAN.
