The invention provides a distributed torque distribution method and device of a vehicle, the vehicle and a storage medium, and the method comprises the steps that when the vehicle is in a four-wheel-drive mode distributed driving process, the current steering working condition of the vehicle is recognized; under the condition that the current steering working condition is the insufficient steering working condition or the excessive steering working condition, the actual yaw rate of the vehicle is obtained, and the torque distribution mode of the vehicle is determined according to the speed value of the actual yaw rate and the speed difference value or the speed change rate between the actual yaw rate and the target yaw rate; and based on the torque distribution mode, target torque of at least one driving shaft or at least one driving wheel of the vehicle under the understeering working condition or the oversteering working condition is calculated. According to the method, torque distribution can be carried out according to the change of the yaw velocity of the vehicle so as to respectively calculate the driving torque under different working conditions, so that the yaw torque is actively reduced or increased, the condition of insufficient steering or excessive steering is improved, and the steering stability of the vehicle is improved.

    本申请提供了车辆的分布式扭矩分配方法、装置、车辆及存储介质,其中,方法包括:在车辆处于四驱模式分布式驱动的过程中,识别车辆的当前转向工况;在当前转向工况为转向不足工况或者转向过度工况的情况下,获取车辆的实际横摆角速度,并根据实际横摆角速度的速度值、与目标横摆角速度之间的速度差值或者速度变化率确定车辆的扭矩分配模式;基于扭矩分配模式,计算车辆分别在转向不足工况或者转向过度工况下的至少一个驱动轴或者至少一个驱动轮的目标扭矩。该方法能够根据车辆横摆角速度变化进行扭矩分配,以分别计算在不同工况下的驱动扭矩,从而主动降低横摆扭矩或提升横摆扭矩,以改善转向不足或者转向过度的情况,提高车辆转向稳定性。
