The embodiment of the invention provides a power-assisted steering system control method and device, electronic equipment and a storage medium. The method comprises the following steps: determining initial rack position data for a rack; obtaining steering data and current rotating speed data of a steering wheel; determining current rack position data based on the steering data, the initial rack position data and a preset line angle rotation ratio; based on the steering data, a preset line angle rotation ratio and the current rack position data, determining a current tail end actual position gap for the rack; determining target rotating speed data for the steering wheel according to a preset standard based on the current tail end actual position gap; based on the current rotating speed data and the target rotating speed data, a tail end protection torque temporary value for the tail end of the rack is determined; and the tail end protection torque for the rack is determined based on the tail end protection torque temporary value, and the tail end protection torque is adopted to control the power-assisted steering system, so that the tail end of the rack is protected, mechanical impact is avoided, and the user experience and safety are further improved.

    本发明实施例提供了一种助力转向系统控制方法、装置、电子设备及存储介质,通过确定针对齿条的初始齿条位置数据;获取方向盘的操舵数据和当前转速数据;基于操舵数据、初始齿条位置数据和预设线角转动比确定当前齿条位置数据;基于操舵数据、预设线角转动比、当前齿条位置数据确定针对齿条的当前末端实际位置间隙;基于当前末端实际位置间隙按照预设标准确定针对方向盘的目标转速数据;基于当前转速数据和目标转速数据,确定针对齿条的末端的末端保护力矩临时值;基于末端保护力矩临时值确定针对齿条的末端保护力矩,并采用末端保护力矩控制助力转向系统,从而实现针对齿条末端进行保护,避免发生机械撞击,进一步地提升了用户体验和安全性。
