Vehicle network system communication error detection

In this paper, the method of handling data communication errors has been studied, several frame structures and their error control methods of vehicle network system have been analyzed. Based on the example of detection failures of error frames in vehicle network, a transmission method based on different data structures and transmission time were put forward, in order to ensure that the important data related to driving safety can be reliably transmitted. Theoretical analysis and simulation results show that this method has a strong compatibility, and can effectively solve CAN network error frames' detection failure problems with only slightly increment of the bus load.
