The invention relates to a corner closed-loop control method and system based on a kingpin steering wheel corner, and the control method comprises the following steps: calculating a wheel target rotating speed through angle closed-loop control according to a VCU (Vehicle Control Unit) and a current wheel corner, and calculating a wheel target rotating speed according to the wheel target rotating speed and a wheel actual rotating speed; and the torque actually required by wheel rotation is calculated through rotating speed closed-loop control. The invention provides a method and a system for closed-loop control of a kingpin steering angle. The method and the system are used for following control of a kingpin vehicle wheel angle. According to the method, the current actual wheel speed and the target demand speed can be calculated through a vehicle steering angle demand signal and a vehicle current wheel steering angle state signal according to the characteristics of a kingpin steering system, the motor target torque is calculated according to the difference between the target angle and the current angle and applied to a power-assisted steering motor, and angle closed loop is achieved; therefore, the wheel steering is realized.

    本发明涉及一种基于主销转向车轮转角的转角闭环控制方法及系统,控制方法包括以下步骤:根据整车控制器VCU和当前车轮转角通过角度闭环控制计算出车轮目标转速,根据车轮目标转速和车轮实际转速,通过转速闭环控制计算出车轮旋转实际需求的扭矩。本发明提出了一种主销转向转角闭环控制的方法及系统,用于主销车辆车轮转角跟随控制;该方法可根据主销转向系统的特征,通过车辆转角需求信号与车辆当前车轮转角状态信号计算出当前车轮实际速度和目标需求速度,并根据目标角度和当前角度之差计算出电机目标转矩施加到转向助力电机,实现角度闭环,从而实现车轮转向。
