The invention relates to a braking efficiency decline compensation method and device, a vehicle and a storage medium in the technical field of vehicle braking, and the method comprises the steps that in the vehicle braking process, the brake disc temperature and the required braking force of the vehicle at the current moment are determined; determining a target friction coefficient corresponding to the temperature of the brake disc from a friction coefficient curve, wherein the friction coefficient curve is constructed according to a corresponding relation between the temperature of the brake disc and the friction coefficient; according to the target friction coefficient and the braking force parameters of the vehicle, actual braking force provided by a brake disc of the vehicle is determined; and according to the required braking force and the actual braking force, target compensation torque is determined, and the target compensation torque corresponding to the current moment is compensated through the recovery torque of the driving motor. And the safety risk caused by the heat fade of the braking efficiency of the vehicle is reduced, and the safety of vehicle driving is improved.
