The invention discloses an electronic power steering system control method. The electronic power steering system judges the relation between the rotating speed of an EPS motor and the minimum reference rotating speed in real time in the vehicle travel process; when the rotating speed of the EPS motor is smaller than the minimum reference rotating speed, the clamping stagnation prevention function is activated, and the vibration torque is output to the EPS motor; and when the rotating speed of the EPS motor is not smaller than the minimum reference rotating speed, the clamping stagnation prevention function is closed, and the vibration torque is not output to the EPS motor. The sudden drop of hand power of a driver due to clamping stagnation of the electronic power-assisted steering system can be prevented.

    本发明公开了一种电子助力转向系统控制方法,电子助力转向系统在车辆行程过程中实时判断EPS电机转速与最小参考转速的关系;当EPS电机转速小于最小参考转速时,激活预防卡滞功能,输出振动扭矩至EPS电机;当EPS电机转速不小于最小参考转速时,关闭预防卡滞功能,不输出振动扭矩至EPS电机。本发明能够预防电子助力转向系统卡滞导致驾驶员手力骤降。
