摘要
根据驱动力控制系统的组成,结合已有的文献,通过比较分析建立了适宜的模糊控制规则,进行了模糊控制器的设计.结合差速器和魔术公式轮胎数学模型,在MATLAB/Simulink环境下构建了仿真系统.对车辆起步、行进中和爬坡时遇到对开路面后的驱动力管理过程进行了仿真,通过和没有进行驱动力控制、逻辑门限驱动力控制的车辆的比较研究表明,所建立的模糊控制算法可以有效地缩短车辆打滑时间,减少不稳定状态,更好地发挥高附着侧车轮的功率,从而提高车辆越野行驶能力.
According to the traction control system components, the author designed a suitable fuzzy control unit and also established a complete simulation system in Simulink environment using the magic tire formula and differential mathematical models. The control effect on many complicated roads was simulated when the driving wheel began to slip. Compared works with no TCS control and the logic threshold TCS control cars, the simulation results show that the fuzzy control strategy established in this article can effectively reduce the skidding time, enhance system instability, produce more power in the high side wheel and improve the drive ability of off-road vehicles.
