This topic comes from Institute for the internal combustion engine, School of Energy and Power Engineering, Shandong University developed the project of "test bed heater" project for Hebei Hongye vehicle heater Co. Ltd.Vehicle heater has been developing rapidly these years. It is now widely used in large-scale passenger cars, trucks, military vehicles, tanks and high-class cars. It can be a very good solution to the cold-start problem and the issue of room heating of vehicle in the cold season and cold regions. Now Hebei Hongye vehicle heater Co. Ltd. has two production lines, turning out over 30 varieties of products, including FJ, YJ, FJH, YJH, YJP, HYD, D5LC, D3LCC, etc. The factory test is the most important aspect of the production line.The vehicle heater Test-bed is an important equipment for vehicle heater to be inspected and researched, In order to inspect heater more quickly and safely, and also improve corporation’s economic benefits, It’s necessary to design the vehicle heater Test-bed control with the computer.Firstly, this paper introduces the development of computer control theory and the testing process of vehicle heater. According to the request for testing, the scheme of test-bed is present and selects sensors and apparatus. Secondly, based on the analysis of system’s hardware, the paper finished the design of this test-bed controller, including the design of hardware and software. Thirdly, how to design this test-bed’s software of computer control is introduced. Finally, a study on system commissioning is presented at last in the article.The practical shows that the system design is feasible and reaches the requirements present.
