The invention provides a motor current control method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that when the new energy vehicle meets a preset motor active short-circuit control condition, an active short-circuit control request about a driving motor of the new energy vehicle is generated; acquiring a request torque for driving a motor; when the request torque does not meet the preset current guiding condition, performing active short-circuit control on the driving motor according to the active short-circuit control request; and when the request torque meets a preset current guide condition, performing guide control on the current of the driving motor within a preset time until the current of the driving motor is guided to a preset steady-state value, and after the preset time, performing active short-circuit control on the driving motor according to the active short-circuit control request. When corresponding conditions are met, the current of the driving motor is guided and controlled before the driving motor enters active short circuit control, so that the influence of active short circuit and the like on the vehicle is optimized.

    本发明提供了一种电机电流控制方法、装置、车辆及存储介质,涉及车辆技术领域。该方法包括:当新能源车辆满足预设电机主动短路控制条件时,生成关于新能源车辆的驱动电机的主动短路控制请求;获取用于驱动电机的请求扭矩;当请求扭矩不满足预设电流引导条件时,根据主动短路控制请求对驱动电机进行主动短路控制;当请求扭矩满足预设电流引导条件时,在预设时间内对驱动电机的电流进行引导控制,直至将驱动电机的电流引导至预设稳态值,经过预设时间后,根据主动短路控制请求对驱动电机进行主动短路控制。本发明通过在满足相应条件时,在驱动电机进入主动短路控制前对驱动电机的电流进行引导控制,以优化主动短路等对车辆造成的影响。
