根据车辆的基本动力学特性，分析了轮胎非线性对于车辆横摆稳定性的影响，建立了包括主动横向稳定杆与 AFS 的整车动力学模型。根据主动横向稳定杆和 AFS 两个系统的运动耦合关系，分别设计了主动横向稳定杆与AFS 的各个子控制器，并设计了前后主动防侧倾力矩分配模糊 PID 控制器，实现两个子系统的协调控制，提高了车辆转向时的侧倾与横摆稳定性。在 MATLAB／Simulink 环境中，对车辆在转向工况下进行了仿真研究，利用 Carsim 软件对仿真结果进行了验证，结果证明了两者协调控制策略的有效性。
根據車輛的基本動力學特性，分析瞭輪胎非線性對于車輛橫襬穩定性的影響，建立瞭包括主動橫嚮穩定桿與 AFS 的整車動力學模型。根據主動橫嚮穩定桿和 AFS 兩箇繫統的運動耦閤關繫，分彆設計瞭主動橫嚮穩定桿與AFS 的各箇子控製器，併設計瞭前後主動防側傾力矩分配模糊 PID 控製器，實現兩箇子繫統的協調控製，提高瞭車輛轉嚮時的側傾與橫襬穩定性。在 MATLAB／Simulink 環境中，對車輛在轉嚮工況下進行瞭倣真研究，利用 Carsim 軟件對倣真結果進行瞭驗證，結果證明瞭兩者協調控製策略的有效性。

The influence of nonlinear tires on the vehicle yaw stability was researched.The dynamics model of a full vehicle equipped with an active roll stabilizer and an active front steering system was set up based on the vehicle dynamics theory.Also a controller combining the active roll stabilizer and active front steering system was designed based on the motion coupling relationships between them.Moreover,an active fuzzy PID controller for regulating the anti-roll moment distribution was designed to coordinate the two systems and enhance the vehicle roll and yaw stability during steering.The vehicle in the steering situation was simulated with the MATLAB /Simulink,and the simulation results were verified by using the Carsim software.The results show the effectiveness of the proposed coordinated control strategy.
