The invention provides a vehicle transient torque control method, a vehicle transient torque control device, vehicle transient torque control equipment and a medium. Determining a corresponding reference corner radian when the vehicle passes through the transmission gap area based on a first corner radian rotated by the motor and a second corner radian rotated by the electric drive output end; after it is recognized that the vehicle enters the transmission gap area again, the corresponding real-time corner radian is determined; based on the radian deviation value between the reference corner radian and the real-time corner radian, the corresponding motor target angular speed when the vehicle is located in the transmission gap area is determined; and determining the target torque of the motor based on the target angular velocity of the motor and the current actual angular velocity of the motor, and performing torque control. The rotating speed closed-loop control is carried out on the motor torque of the transmission clearance area, so that the gear collision kinetic energy when the reverse driving is completed is reduced, and the influence of the transmission clearance area on the vehicle drivability during the transient torque conversion of the vehicle is reduced.

    本申请提供了一种车辆瞬态扭矩控制方法、装置、设备及介质,所述方法包括:在识别到车辆通过传动间隙区的情况下,基于电机所转过的第一转角弧度和电驱动输出端所转过的第二转角弧度确定车辆通过所述传动间隙区时对应的基准转角弧度;识别到车辆再次进入所述传动间隙区后,确定对应的实时转角弧度;基于所述基准转角弧度和所述实时转角弧度之间的弧度偏差值确定车辆处于所述传动间隙区时对应的电机目标角速度;基于所述电机目标角速度和所述电机当前实际角速度确定电机目标扭矩并进行扭矩控制。本申请通过对传动间隙区的电机扭矩进行转速闭环控制,降低了驱动反向完成时的齿轮撞击动能,减小了车辆瞬态扭矩转换期间传动间隙区对车辆驾驶性的影响。
