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 is improved.

    本申请提供了一种后桥控制方法、装置、存储介质和车辆,属于汽车技术领域,该方法包括:在车辆行驶的过程中,确定车辆的动力模式和驾驶模式;若车辆的动力模式为直驱模式,且车辆的驾驶模式为预设的目标模式,确定车辆的行驶参数;若车辆的行驶参数满足后桥脱开条件,控制车辆的脱开机构脱开后桥的电机和半轴。通过本方案,在后桥无需提供驱动力时,能够将后桥电机与半轴脱开,这样在后桥无需提供动力的情况下,后桥电机可以不再空转,防止了后桥电机空转造成能量损耗,进而提高车辆的经济性。
