摘要
针对汽车底盘两系统集成控制由于控制器作用范围有限,使得控制结果难以满足汽车在全工况下整车性及安全性这一问题,本研究综合考虑了汽车的纵向、横向和垂向动力学对整车安全性的影响以及三者之间的关系,并基于14自由度的整车模型建立了PID算法的集成控制器,同时进行了仿真验证。仿真结果表明:多系统的集成控制优于两系统的集成控制,有效地提高了整车的综合性能。
In two integrated control system research,it is difficult for the control result to meet the conditions of the whole vehicle performances and safety requirements because of the limited scope of the controller.Therefore,considering the cars with longitudinal,lateral and vertical dynamics relationships on vehicle safety,an integrated controller is established with PID approach based on a 14-DOF vehicle model and simulation results are analyzed.The results show that the integrated control chassis based on multi-system is better than two integrated control system and it can effectively improve the overall performance of the vehicle.
