汽车主动悬架的整车控制方法及仿真研究

A study on the entire vehicle controlling method and simulation of the initiative suspension frame of automobile

为了提高车辆主动悬架系统的性能,改善车辆的乘坐舒适性和操纵稳定性,针对汽车主动悬架整车控制方法问题。以1/4车体模型,基于8板块的整车控制算法(Octa-Plate Control Method,OPCM),对汽车主动悬架整车控制方法进行了探讨,并进行了仿真性研究。仿真结果表明:OPCM对车辆的垂直运动和车辆姿态控制都是非常有效的。同时,这种算法仅需要测量每个驱动机构未端的加速度,需要的传感器少,实现非常简单。因此,是一种较为理想的低成本控制算法,从而具有更大的实用价值。

For the sake of enhancing the performance of initiative suspension frame of vehicles and improving the riding comfortness and the manipulative stability of vehicle and aimed at the problems of entire vehicle controlling method of the automobile initiative suspension frame, a discussion based on the Oct-Plate entire vehicle Controlling algorithmic Method （OPCM） of a model of 1/4 vehicle body has been carried out on the entire vehicle controlling method of automobile initiative suspension frame and a study of simulative-ness was carried out. The result of simulation indicated that the OPCM is very effective both on the vertical movement of vehicle and on the posture control of vehicle. At the same time, this kind of algorithm needs only to measure the acceleration of every end of the driving mechanism and requires fewer sensors and was quite simple in realization. Therefore, it is a kind of rather ideal controlling algorithm of low cost, thus possesses more values of application.
