一种测试CAN总线抗电磁干扰能力的方法和装置
摘要：
一种测试CAN总线抗电磁干扰能力的方法，用金属导线连接被测CAN总线电子控制装置[21]的CAN总线接口和CAN总线终端[I]的CAN总线接口，使CAN电子控制装置[21]与的CAN总线终端[I]之间通过CAN总线进行信息交互，电磁干扰耦合装置将电磁干扰信号施加到CAN总线的金属导线上，再利用CAN总线终端的通信故障监测功能判断在规定的时间范围内是否产生通信故障，以此评价CAN总线电子控制装置[21]的抗电磁干扰能力。应用该方法的装置中包括具有CAN总线通信故障监测功能的CAN总线终端[I]，CAN总线终端[I]有与被测CAN总线电子控制装置[21]的CAN总线物理层相同的CAN总线物理层，即相同型号的CAN总线收发器，按照相同的CAN总线收发器电路原理及相同的印刷电路板设计规则设计的CAN总线物理层。
摘要（英）：

This is a test method of anti-electromagnetism interfere capability of CAN bus. The CAN bus interface of the CAN bus electron controlling equipment connects with CAN bus interface of CAN bus terminal by metal line to exchange the communication between the CAN electron controlling equipment and CAN bus terminal through CAN bus. The electromagnetism disturb signal is added to the metal line of CAN bus by electromagnetism disturb coupling equipment. Estimate whether communicate trouble has come into being in the prescriptive time by the communicate trouble inspect function of the CAN bus, and estimate the anti-electromagnetism interfere capability of the CAN bus electron controlling equipment. The equipment has the CAN bus terminal with the communicate trouble inspect function. CAN bus terminal has the same CAN bus physics layer same as the one of the CAN bus electron controlling equipment which is the same type of CAN bus transceiver designed according to the same CAN bus transceiver circuit principle and same printing circuit plant designing rule.
