The invention discloses a danger sounding and preventing method for improving the door opening safety after parking, and belongs to the field of door locks on automobile bodies. The danger sounding and preventing method comprises the following steps: detecting the distance between objects after parking, and judging whether objects are close to an automobile or not; if the objects are close to the automobile, sending the distance to a controller; judging that the objects are still or mobile by the controller through a preset algorithm; if the objects are mobile, calculating out the time that the objects are close to the automobile; judging whether an automobile door is locked or unlocked through comparison between the time and the preset safety time; sending an unlocking/locking signal into a door lock motor, and controlling the opening/closing of the automobile door by the door lock motor. The danger sounding and preventing method adopts an active safety protection manner, and is safer when compared with the conventional manual judging method by a driver.
