In order to improve hybrid electric vehicle’ s safety and reliability, this paper used the Lab-VIEW to develop CAN network online monitoring and fault diagnosis function of the combination of diagno-sis system. The system can monitor the parameters of the controller node state on-line, and can analysis of hybrid power system parameters and fault data, according to the fault diagnosis module, and was given the appropriate solutions. Through the hardware in the loop simulation test, the results show that this sys-tem can real-time monitoring of hybrid systems in the various state of the node, can also according to the parameters of the entire vehicle fault diagnosis and analysis, the real time and the reliability of the system can meet the requirements of hybrid electric vehicle.
