摘要
在Matlab/Simulink中建立了包括横摆运动、侧倾运动的八自由度整车动力学模型和车辆参考模型。采用车辆横摆角速度的状态差异法,基于模糊控制理论制定了直接横摆控制策略,实现了ESC系统对车辆的稳定性控制。对典型工况鱼钩试验进行仿真分析。结果表明:所制定的控制策略可以有效地实现横摆稳定性控制,而且减小了侧向加速度,使汽车具有一定的抗侧翻能力,提高了汽车的稳定性和安全性。
The vehicle reference model, and a 8-DOFs vehicle dynamics model covering yaw and roll motion are established in Matlab/Simulink. Using the method of different states of yaw angle, a direct yaw control strategy has been proposed based on fuzzy control principle, then the stability control of the vehicle ESC system is achieved. The results of fishhook test simulations in characteristic cycles show that the designed control strategy can effectively implement yaw stability control and reduces lateral acceleration. Furthermore, the vehicle＇ s anti-rollover capacity is increased, and the stability and safety of the vehicle are enhanced.
