【摘要】为了使机械式自动变速器(AMT)的控制器产品测试摆脱在传统测试方法中需要实物传感器和笨重机构的限制,根据AMT控制器的控制原理,利用嵌入式系统开发方法设计开发了一套自动测试系统.测试系统主要基于电子电路原理,利用各种电子元器件来模拟AMT的各种传感器信号和机构的响应,并通过程序实现自动检测.另外基于LabWindows/CVI的平台开发了测试监控软件,使测试结果一目了然.试验结果表明,利用该测试系统可快速、自动完成对AMT控制器的测试,并可快速定位控制器的潜在故障.%To get rid of the limitation of using physical sensors and actuators to test the product of AMT control unit, an automatic test system is designed and developed based on the control principle of AMT control unit and adopting embedded system development methods. This test system is mainly based on electronic circuit theory, using a variety of electronic components to simulate the signals of various sensors and the response of AMT actuators. The programs in the test system are designed to accomplish automatic detections. A test monitoring software is developed in the environment of LabWindows/CVI to display the results. Experiments show that the test of AMT control unit can be done quickly and automatically with this test system, and the potential problem zones of AMT control unit can
