Reliable Assessment of CAN Bus

Based on the most impossible fault path method the paper proposes to create a reliable model to the network structure of CAN bus with the intelligent node. By computing, we can see that the average non-fault working time MTF of CAN bus declines with the enhancement of the system lapsed time n in the maximum transmission time. With the movement of n, the non-efficiency U increases linearly. That is to say, the larger of n, the lower of reliability. Therefore, considering the reliability of CAN bus, the less of intelligent node layer, the better of reliability.
