汽车PEPS系统诊断测试的应用与研究

随着汽车技术的不断提高,汽车PEPS系统也对其诊断测试结果的速度、准确性、连续性提出了更高的要求,利用Vector公司开发的CANoe总线仿真软件,对各种车身电子模块进行模拟,建立具有改进AES算法认证加密的汽车PEPS系统的测试仿真环境。实际测试结果表明,该系统不仅可以在虚拟节点下进行模拟仿真测试,也可以在真实节点下进行实时测试,灵活有效地反映出汽车PEPS系统中各种电子模块的总线通信情况,同时保证了故障诊断测试连续性和有效性。

Research and Application of the Diagnostic Test of PEPS System for Automobile

With the continuous improvement of automotive technology, passive entry and passive start （PEPS） system for car put forward higher request of test speed and continuity of its diagnostic test results. Using the CANoe bus simulation software developed by Vector company simulate all kinds of electronic modules of automobile body which can establish a complete simulation test environment of PEPS system based on improved AES algorithm. The practical test results show that this test system can test not only in the virtual node in the simulation mode but also in the real node mode, it can flexibly and effectively reflect the car bus communication situation of various electronic modules in the system, at the same time guarantee the continuity and the validity of fault diagnosis text.
