The invention discloses a safety air bag, a vehicle and a control method, the safety air bag comprises an air bag, an explosion generator and a driving module, the air bag comprises a main air cavity and a three-dimensional air cavity, and the main air cavity is provided with a plugging piece; in the unfolded state, the main air cavity is formed in the side, facing a seat, of a steering wheel hub, and the three-dimensional air cavity is formed in the periphery of the steering wheel hub. The ignition generator is communicated with the main gas cavity; the driving module is connected with the plugging piece. The vehicle comprises the safety air bag. The control method comprises the steps that when the steering wheel is in a normal state, the airbag control module controls the explosion generator to act; in the folding state, the airbag control module controls the explosion generator and the driving module to act simultaneously. The invention relates to the field of vehicle safety, and provides a safety air bag, a vehicle and a control method, the size of the air bag can be changed according to the folding condition of a steering wheel to guarantee supporting of the air bag, a self-adaptive structure is formed, and the problem of safety protection of a driver when the steering wheel is in a folded state or a non-folded state is solved.
