【摘要】 本文以大学生方程式赛车为研究对象,提出了一种四轮转向系统结构以及控制策略。在CarSim中建立整车模型联合Simlink进行仿真,对比了前轮转向,前后轮比例控制四轮转向,前后轮比例控制+横摆角速度反馈控制四轮转向三种不同的转向系统,通过仿真结果证明了四轮转向系统能有效提升车辆操纵稳定性。更多还原

【Abstract】 In this paper,a four-wheel steering system structure and control strategy are proposed by taking the Formula Student racing car as the research object.The vehicle model is established in CarSim and Simulink is used for simulation,and three different steering systems are compared:front wheel steering,front and rear wheel proportional control four-wheel steering,front and rear wheel proportional control+yaw rate feedback control of four-wheel steering,and the simulation results prove that The four-wheel steering system can effectively improve the handling stability of the vehicle.更多还原
