The embodiment of the invention relates to a vehicle torque distribution method and device, a vehicle and a storage medium, and belongs to the technical field of automobiles. The method comprises the steps that a constant-speed torque distribution coefficient and an acceleration torque distribution coefficient are determined according to speed parameters of a vehicle, the constant-speed torque distribution coefficient is a torque distribution coefficient of the vehicle in a constant-speed state, and the acceleration torque distribution coefficient is a torque distribution coefficient of the vehicle in an acceleration state; according to the acceleration of the vehicle, a first weight coefficient of a constant-speed torque distribution coefficient and a second weight coefficient of an acceleration torque distribution coefficient are determined, and the weight coefficient corresponding relation comprises a preset corresponding relation between the acceleration and the first weight coefficient and the second weight coefficient; and according to the first weight coefficient and the second weight coefficient, performing weighting processing on the constant-speed torque distribution coefficient and the acceleration torque distribution coefficient to obtain a target torque distribution coefficient. According to the method, the current torque distribution of the vehicle can be adjusted in time according to the real-time attitude of the vehicle in the driving process, and the risk of vehicle instability is reduced.
