Abstract
CAN bus is widely used in automotive distributed embedded systems. Its protocol makes it reliable and efficient in in-vehicle communication system and industrial control system. However, the limited communication bandwidth limits its transmission efficiency. In order to improve the transmission efficiency of CAN bus, the influence of CAN bus structure to the transmission performance is analyzed in this paper. A typical CAN bus network is set and the message transmission is simulated under different CAN bus structure based on CANoe, which is widely used to study the CAN bus. The influence of different network structure on the transmission performance is analyzed. The simulation result demonstrated that the multi-level-bus CAN network using gateway reduces busload and minimize message delay effectively. It is also demonstrated that the simulation method is able to be used to find the appropriate CAN bus network structure according the busload or message delay requirement.
