The invention discloses an electric power steering control method, device and equipment and a storage medium. The method comprises the steps: acquiring sensor signals of a controller area network CANbus, motor rotating speed signals of a motor and limit position signals under the current working condition; determining whether to activate a corner rotating speed limiting function according to thelimit position signal and the sensor signal; when determining that the corner rotating speed limiting function is activated, combining the preset rotating speed limiting algorithm and the preset rotating angle limiting algorithm to obtain the motor limiting current, and reducing the power-assisted torque according to the motor limiting current to achieve power-assisted steering control. Therefore,under the condition that the steering wheel tends to the limit position, the steering angle rotating speed is limited; the limiting assisting current is generated in time, the soft dead center activecollision restraining function is achieved, various using working conditions can be adapted according to the speed of a driver rotating a steering wheel to get close to the limit position and the difference of associated vehicle speeds, and the actual using requirement of a vehicle can be better met.

    本发明公开了一种电动助力转向控制方法、装置、设备及存储介质,所述方法通过获取控制器局域网络CAN总线的传感器信号,电机的电机转速信号及当前工况下的极限位置信号;根据极限位置信号和传感器信号确定是否激活转角转速限制功能;在确定激活转角转速限制功能时,结合预设转速限制算法和预设转角限制算法获得电机限制电流,并根据电机限制电流降低助力力矩,以实现助力转向控制,能够保证方向盘在趋向极限位置的情况下,通过对转角转速进行限制,及时产生限制助力电流,实现软止点主动碰撞抑制功能,可以根据驾驶员转动方向盘接近极限位置的快慢,以及关联车速的不同,能够适应多种使用工况,可以更好的贴合车辆实际使用需求。
