Problems solved by technology

And even if the driver confirms whether it is safe to open the door and get off the car through the interior rearview mirror or the rearview mirrors on both sides, this method of judging through the rearview mirror is also an aid for the driver to get off the car safely. Judgment conditions, but this is a form of passive safety, which relies on the driver's good habits and active safety awareness, with great personal subjective awareness. In many cases, the driver does not judge due to negligence due to fatigue and other reasons. rear danger
Moreover, this method cannot remind the rear passengers. Most passengers do not have the awareness of observing the rearview mirror. When the driver does not remind in place or has no time to remind, the rear passengers get off suddenly due to parking. If they run into pedestrians or other objects quickly close, it may cause irreversible consequences

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile body door lock control, in particular to a danger detection and prevention method for improving the safety of parking and opening a door. Background technique [0002] In daily life, it is often encountered that the driver parks on the side of the road, and even some taxi drivers drop off passengers and stop in the middle of the road in order to hurry. In the event of a collision accident, if it is serious, it will also cause casualties. As a result of this type of accident, according to the regulations, the driver of the parking motor vehicle bears the main responsibility or the full responsibility. [0003] At present, when parking and getting off, the rear passengers can automatically open the rear door lock switch, open the door and get off without the driver opening the door. And even if the driver confirms whether it is safe to open the door and get off the car through the interior rear...
