中文摘要：
为提高汽车转向行驶时的乘坐舒适性和操纵稳定性,建立了汽车电动助力转向系统（EPS）的多刚体动力学模型和多自由度的包含主动悬架系统（ASS）的整车动力学模型,根据转向和悬架两个系统之间的运动耦合关系,设计了EPS和ASS集成控制系统,对EPS采用了PID控制策略,ASS采用了预测控制策略。在MATLAB环境下的仿真结果表明：集成控制方法能够有效的改善车辆的操纵稳定性及平顺性,其控制效果优于单独控制。
英文摘要：
In order to improve vehicle comfort and maneuverability when steering, a vehicle electricalpower steering system multibody dynamics model and a multi-degrees of freedom model of full vehicle including active suspension system were set up. An integrated control system was set up based on motion coupling relationship between steering and suspension systems. The P1D control strategy for the EPS and the MPC control strategy for the ASS were designed. Under Matlab, the simulation results show that the presented control scheme can achieve better vehicle maneuverability and ride comfort than separate control.
