The invention provides a rack tail end protection method and device, a storage medium and a vehicle, and belongs to the technical field of vehicles. The method comprises the steps that the rotating speed value and the rotating angle value of a steering wheel in the current direction are obtained; determining a rack tail end protection angle range based on the rotating speed value and a steering limit angle of the steering wheel in the current direction; based on the rotation angle value and the rack tail end protection angle range, a power-assisted current limiting value corresponding to the rotation angle value is determined; under the condition that the assistance current limiting value is larger than the target assistance current, the target assistance current is output as final assistance current; otherwise, outputting the boosting current limit value as the final boosting current. According to the embodiment of the invention, a proper rack tail end protection angle range can be matched based on the rotating speed value and the steering limit angle of the steering wheel in the current direction, so that the rack tail end is more flexibly protected, the applicability is high, and the problem that rack tail end protection functions of the same vehicle and different vehicles of the same vehicle type are inconsistent is effectively solved.

    本申请提供了一种齿条末端保护方法、装置、存储介质和车辆,属于车辆技术领域,方法包括:获取方向盘在当前方向上的转速值和转角值;基于转速值以及方向盘在当前方向上的转向极限角度,确定齿条末端保护角度范围;基于转角值和齿条末端保护角度范围,确定转角值对应的助力电流限制值;在助力电流限制值大于目标助力电流的情况下,输出目标助力电流为最终助力电流;否则输出助力电流限制值为最终助力电流。本申请实施例能够基于转速值以及方向盘在当前方向上的转向极限角度,匹配合适的齿条末端保护角度范围,进而更加灵活地对齿条末端进行保护,适用性强,有效解决同车型同一车辆和不同车辆齿条末端保护功能表现不一致的问题。
