With the maturity of relevant technologies, hardware in loop simulation in its development cycle is short, low cost and close to the actual situation is the development of automotive electronic control system, the main research tool. This paper studies the use LabVIEW software to simulate the Jetta cars stability control system controller, through the use of LabVIEW software, programming and control algorithms to realize the wheel brake pressure distribution and the completion of the controller hardware detection task. Test stand is mainly to computers and hardware, such as: sensors, actuators connected together to form a complete vehicle stability control system. LabVIEW software platform based on the establishment of a vehicle driving stability control hardware in the loop simulation platform, through the platform of the controller hardware in the loop simulation. The results Biaoming the controller stability, control algorithm Keyiyouxiao driving wheel of the slip control significantly improve the Ju Liangs start Jiasuxingneng, for the Shi vehicle testing and electrical units and lay
