四轮独立驱动电动汽车四轮转向和横摆力矩联合控制仿真
Integrative Control Simulation of Four?wheel Steering and Yaw Moment Control of Four?wheel Independent Drive Electrical Vehicle
摘要
Abstract
To enhance mobility at low vehicle speed and stability at high vehicle speed for four-wheel in-dependent drive electric vehicle, a control strategy combined with four-wheel steering and yaw moment has been proposed.To overcome the disadvantages of the traditional fuzzy controller,which contains fixed parame-ters and control rules,low adaptive ability and etc,an online parameter self-adjusting fuzzy controller was de-veloped.Under conditions of sharp double lane change at low speed and continuous sinusoidal at high speed, an analysis was carried out by the co-simulation model built by the Matlab/Simulink and CarSim software.The comparison among the three control strategies,which are the no control,the parameter self-adjusting fuzzy con-trol and the parameter self-adjusting fuzzy control,show that the mobility at low vehicle speed and the stability at high vehicle speed have obviously been improved for the parameter self-adjusting fuzzy control strategy.关键词
