The invention provides a vehicle steering control method, a vehicle steering assist system and a control unit thereof. The control unit comprises an acquisition module configured to acquire vehicle steering state information including wheel speed information, vehicle speed information, steering wheel angle information and vehicle body yaw rate information; the judging module is configured to judge the current steering state of the vehicle based on the obtained vehicle steering state information, and the current steering state comprises the current vehicle speed state, the current steering wheel angle state and the current yaw rate state; and a decision module configured to decide to execute one or more of a plurality of predetermined steering control strategies based on the current steering state of the vehicle, the predetermined plurality of steering control strategies includes first and second steering control strategies implemented by a first actuator and third and fourth steering control strategies implemented by a second actuator. The first actuator and the second actuator are decoupled.
本发明提供了车辆转向控制方法、车辆转向辅助系统及其控制单元。该控制单元包括:获取模块,配置成获取车辆转向状态信息,其包含:轮速信息、车速信息、方向盘转角信息以及车身横摆率信息;判断模块,配置成基于获取的车辆转向状态信息判断车辆的当前转向状态,其包含:当前车速状态、当前方向盘转角状态以及当前身横摆率状态;以及决策模块,配置成基于车辆的当前转向状态来决策执行预定的多个转向控制策略中的一个或多个,所述预定的多个转向控制策略包括由第一执行器实现的第一和第二转向控制策略以及由第二执行器实现的第三和第四转向控制策略。第一执行器与第二执行器是解耦的。
