The invention discloses an air spring type semi-active range extender suspension, a control method and a vehicle, and the semi-active range extender suspension comprises a suspension body which comprises a suspension main body and a first shell located below the suspension main body; the top of the suspension body is used for being connected with an engine, the suspension further comprises a second shell, and a second air cavity is formed in the second shell. A first air cavity is formed between the inner wall of the first shell and the bottom of the suspension main body; the first air cavity and the second air cavity are each provided with a switching piece communicating with the first air cavity and the second air cavity, and the air cavities at least have a sealed state or an unsealed state through the switching pieces. The semi-active range extender suspension further introduces a vacuum system, the vacuum system is connected with the end, away from the corresponding air cavity, of the switching piece, and according to the design, the first air cavity and the second air cavity are additionally provided with a third state, namely the vacuum state. Through cooperation of the switching piece and the vacuum system, switching of multiple performance modes of the suspension body is completed, and the suspension body can be better matched with multiple working conditions of a whole vehicle.
