A definition of data transmission efficiency is given for CAN bus system, and the main factors affecting the data transmission efficiency in CAN network are analyzed. Through calculation and comparison, three methods to improve the data- transmission efficiency in CAN network are summed up. They are then combined to form a comprehensive optimization scheme for data transmission efficiency in CAN network, which can effectively u-tilize the transmission resource of CAN network. By using the comprehensive optimization scheme, an improvement design is conducted on the control system of a typical car body CAN network as an example. The results show that using the design method can markedly raise the data transmission efficiency in car body CAN network.
