The embodiment of the invention discloses an engine air inlet control system and method and a hybrid power carrier, and belongs to the technical field of electronic control. The system comprises a vehicle control unit, an engine control unit and an air inlet control unit. The vehicle control unit is used for determining engine compensation power based on the vehicle driving parameters and motor output power and sending the engine compensation power to the engine control unit, and the engine compensation power refers to power needing to be provided by an engine in the driving process of the hybrid power vehicle; the engine control unit is used for determining the engine air inlet demand quantity based on the engine compensation power and sending the engine air inlet demand quantity to the air inlet control unit; the air inlet control unit is used for adjusting the opening and closing proportion of the air inlet valve based on the air inlet demand quantity of the engine, and the opening and closing proportion of the air inlet valve is in positive correlation with the air inlet demand quantity of the engine. By the adoption of the scheme, the engine air inlet control accuracy can be guaranteed, and meanwhile the air inlet control difficulty is reduced.
