The invention discloses a four-wheel independent motor drive articulated vehicle steering control method and device and a vehicle, the four-wheel independent motor drive articulated vehicle steering control method comprises the following steps: detecting the current steering angle of a whole machine, the vehicle speed and the displacement direction and size of a valve core of a steering valve in real time; according to the current steering angle of the whole machine, the vehicle speed and the displacement direction and size of a valve element of a steering valve, a four-wheel differential auxiliary steering control signal is obtained through calculation, and the four-wheel differential auxiliary steering control signal is output according to a set control strategy and used for assisting steering of a hydraulic system. Therefore, unstable shaking of the whole machine during steering starting and steering stopping is improved, impact during steering stopping is reduced, steering energy consumption is reduced, and synchronization of hydraulic steering and differential auxiliary steering is kept.
本发明公开了一种四轮独立电机驱动铰接式车辆转向控制方法、装置及车辆,四轮独立电机驱动铰接式车辆转向控制方法,包括:实时检测整机当前所处的转向角度、车速、转向阀的阀芯位移方向及大小;根据整机当前所处的转向角度、车速、转向阀的阀芯位移方向及大小,计算获得四轮差速辅助转向控制信号,并按照设定的控制策略输出四轮差速辅助转向控制信号,用于辅助液压系统转向,从而改善整机在转向启动、转向停止时的不平稳晃动,减小转向停止时的冲击,降低转向能耗以及保持液压转向与差速辅助转向同步。
