The embodiment of the invention discloses a hybrid power system, a control method and a hybrid power vehicle, and belongs to the technical field of automotive electronics. The system comprises an engine, a motor, a gearbox, wheels, a gearbox protection module and a controller. Wherein the engine is connected with an input shaft of the gearbox, the motor is connected with the input shaft of the gearbox, and an output shaft of the gearbox is connected with a wheel shaft of the wheels through the differential mechanism; the gearbox protection module is used for sending a power limiting signal to the controller under the condition that the gearbox is in the first working state; in the first working state, a power system parameter corresponding to the hybrid power system is larger than a first parameter threshold value, and the duration reaches a first duration; and a controller for controlling output power of the engine and the motor based on the power limit signal. By adopting the scheme provided by the embodiment of the invention, the gearbox can be effectively protected, and the gearbox is prevented from being damaged in a heavy-load working state.
