摘　　要：通过分析2种不同类型的CAN-Bus网络的通信故障,提出了2种检测网络硬故障的方法,通过基于冗余容错技术的CAN-Bus测试平台验证了该方法的可行性,最后指出了该实验方法可以对CAN-Bus通信硬故障进行实时检测,并有效提高CAN-Bus网络的可靠性。Two kinds of CAN-Bus communication faults are analyzed, and then two methods for network hard fault detection are put forward accordingly. The feasibilities of the methods are proved by CAN-Bus test platform based on fault-tolerant redundancy technology. With the methods, reahime detection of CAN-Bus communication hard fault can be performed, and the reliability of CAN-Bus network can be enhanced greatly.
