The invention discloses a system and a method of controlling the starting and stopping of an automobile air conditioner. The method comprises the steps of forbidding an engine from stopping automatically if a first condition is met after an automatic stop signal of the engine is received, otherwise allowing the engine to stop automatically, wherein the first condition refers to that an air conditioner system is in a defrosting or defogging mode, or the environment temperature is higher than a first temperature threshold value or lower than a second temperature threshold value, or the illumination intensity is greater than or equal to an illumination threshold value, or a difference value of a target temperature controlled by the air conditioner system and the temperature in an automobile is greater than a first temperature difference threshold value; requiring to start the engine if a second condition is met after the engine stops automatically, otherwise keeping a stop state of the engine, wherein the second condition refers to that the air conditioner system is in the defrosting or defogging mode, or the temperature variation in the automobile after the engine stops automatically excesses a temperature variation threshold value, or the difference value of the target temperature controlled by the air conditioner system and the temperature in the automobile is greater than or equal to a second temperature difference value. According to the technical scheme, not only can oil consumption be reduced, but also the comfort performance of the air conditioner system can be maintained.
