New standards in the automotive industry highlighted the situation of the actual operation of the alternator and a variety of harsh environment simulation limit test. Using new standards in the automotive industry as a guide, this article presents a virtual instrument based on the durability of automobile generator integrated test system. The design adopt virtual instrument technology in designing the system, Graphic language, LabVIEW is applied in writing measure-control program. The system uses a lot of features on LABVIEW, including Data acquisition, control of serials port, etc. Test implementation uses the host computer via RS232 and RS485 communication port and the data acquisition card, NI PCI- 6221, to control the frequency hybrid motor, temperature control box, electronic loads and other intelligent devices, and to simulate a variety of automotive alternator working conditions and real-time monitoring to monitor the status of generators. Using this system, two separate automobile alternators can be tested in terms of high-speed vehicle impact and high temperature durability test and electrical performance test and other tests at the same time. As a result, the generator speed measurement error is within 1%, the control error is within 2%, voltage and current measurement errors were within 0.5% and 0.4%, which meets the requirements.

As the key part of vehicle control, ECU must be tested after manufacturing. This online function test system aims to automatically test the hardware and software of ECU PCB after they are welded. Ａ test system consisting of upper PC, test board, and tested ECU is built. According to the feature of the ECU (mutibus based, hardware and software included), the communication protocol, as well as testing software for upper and lower devices is developed. This system is easy to be applied and expanded in related ECU PCB testing. Batch test with this test system for newly-produced ECU is implemented, which ensures high quality and stability of the products.
