摘 要 汽车稳定性控制系统通过控制驱动轮滑转状态改善车辆在软弱附着路面的牵引性和操纵稳定性,汽车电控系统开发的实质是进行车辆控制原型及执行器间的性能匹配,但单纯计算机仿真难以完成这一任务。随着相关技术的成熟，硬件在环仿真以其开发周期短、成本低和接近实际情况正成为汽车电控系统开发的主要研究手段。　基于软件平台建立了车辆驱动控制硬件在环仿真平台，通过该平台进行了控制器硬件在环仿真实验。实验结果表明了控制器能够稳定工作，控制算法可以有效控制驱动轮的滑转，显著改善车辆的起步加速性能，为实车试验以及电控单元的进一步开发打下了基础。ABSTRACT Vehicle stability control system to switch the state by controlling the drive roller in the weak attachment to improve vehicle traction and road handling and stability, development of automotive electronic control system is essentially a prototype of the vehicle control and performance matching between the actuator, but the simple computer simulation is difficult to To accomplish this task. 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 the foundation of Jin Yibu development.
