A motor driven power steering control method and a motor driven power steering control system are provided; the method may include setting a virtual friction model to a column connected between a steering wheel and a rack gear; calculating a frictional torque of the column by taking a steering angular speed of the steering wheel as an input parameter in the set virtual friction model; and calculating a target steering torque on the basis of a virtual steering system model using the frictional torque of the column as a parameter.
一种电机驱动动力转向控制方法和电机驱动动力转向控制系统,该方法可包括:对连接在方向盘和齿条之间的柱设置虚拟摩擦模型;通过将方向盘的转向角速度作为所设置的虚拟摩擦模型中的输入参数来计算柱的摩擦力矩;以及基于虚拟转向系统模型使用柱的摩擦力矩作为参数来计算目标转向力矩。
