Abstract: The present application provides an air conditioner control method and apparatus, and an air conditioner. Upon detecting that a user is attempting to kick off a blanket, but has not kicked off the blanket, or upon detecting that the user is sweating, a corresponding air blowing control policy is determined on the basis of the operating mode of the air conditioner. If the air conditioner is operating in a cooling mode, the set air blowing temperature is reduced and the air blowing angle is adjusted to avoid the position where the user is located. If operating in a heating mode, the set air blowing temperature is reduced. Upon detecting that a user has attempted to kick off the blanket and has kicked off the blanket, or upon detecting that the user is not sweating, a corresponding air blowing control policy is determined on the basis of the operating mode of the air conditioner. If the air conditioner is operating in a cooling mode, the set air blowing temperature and the set air blowing speed are reduced, and automatic air oscillation is activated; when operating in heating mode, the set air blowing temperature is increased, and the air blowing angle is adjusted to be oriented toward the position where a specific body part of the user is located. In the present solution, precision control of the air conditioner can be achieved for different user states, ultimately making the sleeping environment more comfortable for the user.
