主要介绍了基于单片机MC9S12XEP100的测试板、CANoe和CANcaseXL的汽车被动进入和一键启动的测试系统.系统中测试板主要模拟汽车上给无钥匙被动进入和一键启动系统提供必要信号的部分系统,CANoe软件用来模拟汽车总线上的各个网络节点,CANcaseXL是一款用于PC和下位机之间通过CAN信号通信的工具,利用三者的配合,可以模拟汽车电子系统中和汽车无钥匙被动进入和一键启动系统交互信息的系统,实现了对无钥匙被动进入和一键启动系统的测试.详细分析了测试系统的原理,以及硬件和软件的设计,为测试汽车被动无钥匙进入和启动系统提供了一个良好的解决方案.%A test system of passive entry and push start (PEPS) system for car based on the test board of MC9S12XEP100, CANoe and CANcaseXL are mainly introduced. The test board mainly simulates the system that supplies signals to PEPS system, CANoe simulates the network node of the car, and CANcaseXL is a tool which achieves the communication of PC to embedded system. According to the cooperation of the three parts, it can simulate all the automotive electronics which communicates with PEPS system and completes the test of PEPS system. The principle of test system, and the design of hardware and software are analyzed in detail, a good solution of the test of PEPS without key system for car is provided.
