The invention provides a gearbox system power assembly working mode control method, device and equipment, and belongs to the technical field of vehicles. The method comprises the steps that vehicle driving data are obtained, and a torque requirement and a gear shifting point are determined according to the vehicle driving data; determining two of the four motors as working motors, namely determining the other two of the four motors as auxiliary motors; a working motor is controlled to start a torque output working mode, and an auxiliary motor is controlled to start an idling working mode, so that a gearbox system is controlled to shift gears according to the gear shifting points; acquiring an auxiliary rotating speed of an auxiliary motor; the auxiliary motor is controlled to be converted into a zero-torque output working mode from an idling working mode; acquiring a working condition point of the working motor; if yes, the auxiliary motor is controlled to be converted into the torque output working mode from the zero torque output working mode so as to control the gearbox system to shift gears according to the gear shifting points. Unnecessary resistance and loss can be reduced, and system efficiency and economical efficiency are improved.
