The invention discloses a torque zero-crossing control method and device of a vehicle and a storage medium. The method comprises the steps that in the vehicle driving process, in response to a received working condition switching instruction, the current driving working condition and the target driving working condition of a vehicle are determined based on the working condition switching instruction; determining transition working condition torque change information of the vehicle based on the current driving working condition and the target driving working condition; based on the transition working condition torque change information, rear motor torque demand change information and front motor torque demand change information of the vehicle are obtained, the rear motor torque demand change information meets a preset torque value, and the front motor torque demand change information does not meet the preset torque value; and performing torque control on the vehicle based on the rear motor torque demand change information and the front motor torque demand change information. According to the invention, the technical problem of impact shaking of the transmission system during working condition switching of the pure electric vehicle in the prior art is solved.

    本发明公开了一种车辆的扭矩过零控制方法、装置及存储介质。其中,该方法包括:在车辆行驶过程中,响应于接收到工况切换指令,基于工况切换指令,确定车辆的当前行驶工况和目标行驶工况;基于当前行驶工况和目标行驶工况,确定车辆的过渡工况扭矩变化信息;基于过渡工况扭矩变化信息,得到车辆的后电机扭矩需求变化信息和前电机扭矩需求变化信息,其中,后电机扭矩需求变化信息满足预设扭矩值,前电机扭矩需求变化信息不满足预设扭矩值;基于后电机扭矩需求变化信息和前电机扭矩需求变化信息,对车辆进行扭矩控制。本发明解决了相关技术中纯电动汽车在工况切换时出现的传动系的冲击抖动的技术问题。
