摘　　要：以某六缸汽车发动机电子控制单元为研究对象,基于Aglient(安捷伦)测控设备和Visual C++6.0、Dreamwaver两款编程软件,结合SCPI指令对电控单元测试系统的硬件和软件部分进行设计。该测试系统通过测控设备仿真汽车发动机上各路传感器信号,电子控制单元接收到传感器信号后进行数据处理并传送到上位机,经上位机的检测处理判断电子控制单元是否返回正确数据,从而达到检测汽车电子控制单元是否符合标准的目的。该测试系统缩短了ECU的检测时间,提高了测试效率,并可对动态数据进行实时监测。In a car with 6-cylinder engine electronic control unit （ECU）as the research object, hardware and software of ECU test system are designed combined with SCPI instructions and based on the Aglient measurement and control equipment, and two sets of programming software of Visual C＋＋6.0 and Dreamwaver. The test system can simulate all the engine sensor signals through the measurement and control equipment, ECU receives the sensor signal, processes the data and transmits to the host computer, which tests and decides whether ECU should return the correct data, so as to test compliance of automobile ECU with the standards. This test system shortens the test time of ECU, improves efficiency and can make real-time monitoring of the dynamic data.
