摘要
论述了基于虚拟仪器技术的汽车发动机ECU自动测试系统的设计,利用各种高精度的板卡模拟ECU各路传感器信号并对ECU进行输出负载仿真,同时通过CAN通讯对其进行监控。软件设计部分选用TestStand作为测试管理软件,利用LabVIEW编写子VI以模块的形式作为测试序列中的测试项进行测试。最后对系统的测试结果进行分析,验证了系统的可靠性和稳定性。
The design of ECU automatic test system based on virtual Instrument was discussed. Using a variety of high precision cards to simulate senor signals of the ECU and output load of ECU was also simulated in this system. Simultaneously,the ECU was monitored via CAN communication. In part of software design,choosing TestStand as test management software,and using sub-VI written by LabVIEW as step of sequence in the form of module for testing. At the end,the test results of system were analyzed to verify the reliability and stability of the system.
