| 摘 要： | 以动力学仿真软件ADAMS建立轮毂电动汽车动力学模型,基于多重假设建立了二自由度4WS车辆模型。根据二自由度车辆模型建立以横摆角速度和质心侧偏角为控制对象的模糊控制策略。以ADAMS/View中的动力学模型和所建立的模糊控制策略进行联合仿真,对比分析角阶跃输入下横摆角速度和质心侧偏角的值。验证了模糊控制下的整车稳定性能比未控制的整车稳定性能好。

| Abstract: | The dynamic model of hub electric vehicle was established by dynamics simulation software ADAMS,and a 2-DOF 4WS vehicle model was established based on multiple assumptions.Based on the 2-DOF vehicle model,a fuzzy control strategy with yaw velocity and centroid deflection angle as the control object was established.The dynamic model in ADAMS/View and the established fuzzy control strategy were used for joint simulation,and the values of yaw velocity and center of mass deflection under the input of angular step were compared and analyzed.It is verified that the vehicle stability under fuzzy control is better than without control. |
