本发明的工作过程如下： 打开电源， 首先为显示器 1与工控机 6共同组成的硬件在环 仿真系统 11供电。 打开安捷伦电源 7的开关， 安捷伦电源 7通过直流电源走线模块 4为 气动双顶针夹具台 9供电。 将被测退役汽车车身电控模块 10置放于气动双顶针夹具台 9 上， 气压驱动装置 5为气动双顶针夹具台 9供气， 气动双顶针夹具台 9夹紧被测退役汽车 车身电控模块 10， 并自动调整被测退役汽车车身电控模块 10的夹紧气压。 登陆硬件在环 仿真系统 11，系统自动检测，大功率高有效桥式输出模拟负载 2模拟驾驶员对车身中中央 门锁控制、 电动车窗控制、 后视镜记忆、 防盗报警控制、 灯光控制、 安全气囊控制、 雨刮 器控制、后备箱开关控制等各种负载工况的负载信号， 并通过气动双顶针夹具台 9传送给 被测退役汽车车身电控模块 10， 该被测退役汽车车身电控模块 10对负载的响应信号通过 气动双顶针夹具台 9和信号调理箱 8传送给硬件在环仿真系统 11。所述硬件在环仿真系统 11模拟车身的各种控制信号，该控制信号通过信号调理箱 8调理后， 由气动双顶针夹具台 9传送给被测退役汽车车身电控模块 10。 硬件在环仿真系统 11对被测退役汽车车身电控 模块 10的响应信号进行检测与记录，并与硬件在环仿真系统 11内存储的标准值进行比较， 以判定响应值是否正确， 从而确定被测退役汽车车身电控模块 10的功能、性能是否完好。 在测试过程中采用自动循环测试的方式，在一个控制循环中顺序完成对被测退役汽车车身 电控模块 10各个功能的测试， 完成多次循环测试过程后， 对比多次测试结果， 对被测退 役汽车车身电控模块 10的各功能进行判定。
以开锁信号为例， 首先启动测试过程进入循环， 开始程序控制， 通过对板卡的信号输 入端控制，连通硬件电路，之后进行数据采集， 由于数据采集有三个端口上触点、下触点、 控制电流进行采集分析， 之后进行比较， 将数据进行整合， 包括信号名称、 信号容许最大 值、 信号容许最小值、 信号测量值、 是否在容许范围内、 测试时间等信息， 在界面表格中 显示， 同时存入指定地址， 然后进行下一个信号的测试。 其中数据采集、 分析处理过程， 采用了子程序的形式进行处理。设计了数据采集通用程序，测试不同模块时只需更换端口 即可。
