Abstract

The invention discloses an automobile and a control method and system thereof. The automobile comprises an air conditioner controller, a gearbox controller and an engine controller. The method comprises the following steps that when the automobile stays in a driving state, whether or not the gearbox controller generates a gear shift signal is judged; if the gearbox controller generates the gear shift signal, information of maintaining an air conditioner state is transmitted to the engine controller; the engine controller generates information for forbidding an air conditioner from being turnedon / off according to the information of maintaining the air conditioner state, and the information for forbidding the air conditioner from being turned on / off is transmitted to the air conditioner controller, so that the air conditioner controller forbids the air conditioner of the automobile from being turned on / off during gear shifting of the automobile conveniently. The control method of the automobile can avoid the situation that unstable influences are caused to an engine when the air conditioner of the automobile and gear shifting of the automobile are changed at the same time; prolonging of the service life of the engine is facilitated, and the automobile and the control method and system thereof are simple and easy to implement.
