The invention relates to the technical field of vehicles, in particular to a wheel end demand torque filtering method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the actual demand torque and the actual torque change rate of the wheel end of the vehicle; selecting a corresponding filter for filtering according to the actual demand torque to obtain a filtering result; and dynamically limiting the filtering result according to the actual demand torque and the actual torque change rate. Therefore, the problems that the smoothness and the response speed of the torque cannot be considered, the applicability is poor and the like when wheel end demand torque filtering is carried out through a fixed torque limit value in the related technology are solved.

    本申请涉及车辆技术领域,特别涉及一种轮端需求扭矩滤波方法、装置、车辆及存储介质,其中,方法包括:获取车辆轮端的实际需求扭矩和实际扭矩变化率;根据实际需求扭矩选择对应滤波器进行滤波得到滤波结果;根据实际需求扭矩和实际扭矩变化率动态限制滤波结果。由此,解决了相关技术中通过固定扭矩限值进行轮端需求扭矩滤波,无法兼顾扭矩的平滑和响应速度,适用性较差等问题。
