Description

Vehicle door opening anti-collision system and vehicle

Technical Field

The utility model relates to the technical field of vehicle control and provides a vehicle door opening anti-collision system and a vehicle.

Background Art

With the rapid development of the automobile industry, the number of cars is increasing. However, when passengers park and open the door, they are too far away from the rearview mirror to observe the road conditions outside the car. They are prone to collision with pedestrians, vehicles, and non-motor vehicles, causing serious economic losses or even life-threatening danger.

To prevent this dangerous situation from happening, major mainstream automobile OEMs have developed and installed the DOW door opening warning function in high-end models. When the rear radar identifies the risk of collision, it will give appropriate reminders to the occupants who are about to open the door and get out of the car to reduce the probability of accidents. However, not all occupants are professionals and have a vague understanding of the sudden warning function. In addition, when both parties are moving at a relatively fast speed, the reaction time is limited, and accidents cannot be avoided, resulting in economic losses and serious threats to the lives of both parties.

Application number: 202110564110.0, Patent name: Vehicle and its door opening anti-collision method, system, device and electronic device, medium. When it is determined that the passengers of the current vehicle have the intention to open the door, and the distance between the current vehicle and the target anti-collision object behind is less than the preset safety threshold, an early warning message is issued. This patent cannot improve the above problems.
