Rear axle control method and device, storage medium and vehicle

The invention provides a rear axle control method and device, a storage medium and a vehicle, and belongs to the technical field of automobiles. The method comprises the steps that in the vehicle running process, the power mode and the driving mode of the vehicle are determined; if the power mode of the vehicle is a direct drive mode and the driving mode of the vehicle is a preset target mode, determining driving parameters of the vehicle; and if the driving parameters of the vehicle meet the rear axle disengagement condition, a disengagement mechanism of the vehicle is controlled to disengage a motor and a half shaft of the rear axle. According to the scheme, when the rear axle does not need to provide driving force, the rear axle motor can be separated from the half shaft, so that the rear axle motor does not idle any more under the condition that the rear axle does not need to provide power, energy loss caused by idle running of the rear axle motor is prevented, and the economical efficiency of a vehicle i
