Vehicle door opening anti-collision early warning method based on V2X

Abstract

The invention relates to a vehicle door opening anti-collision early warning method based on V2X. The method comprises the steps of obtaining driving parameters periodically broadcasted by surrounding vehicles and non-motor vehicles / pedestrians, and the driving parameters at least comprising position information, speed, acceleration and driving tracks; acquiring driving parameters of the current vehicle; screening out surrounding vehicles and non-motor vehicles / pedestrians which have a crossing and overlapping area with the current vehicle driving track; judging whether the crossing and overlapping area covers the position information of the current vehicle or not, and if yes, taking surrounding vehicles and non-motor vehicles / pedestrians corresponding to the crossing and overlapping area covering the position information of the current vehicle as dangerous targets; judging whether the current vehicle is in a static state or not, and if yes, sending an early warning signal to the current vehicle; or else, not giving an early warning prompt. According to the method, non-motor vehicles / pedestrians and traffic participants without V2X equipment can be considered in scene calculation, the defects existing in an existing vehicle door collision prediction method are overcome, and potential accidents can be eliminated.

Description

technical field [0001] The invention relates to the technical field of automobile door anti-collision, in particular to a V2X-based anti-collision warning method for vehicle door opening. Background technique [0002] With the continuous improvement of people's living standards, the penetration rate of vehicles is also getting higher and higher, and the safety problem in the driving process is particularly important. Especially in today's increasingly complex road conditions, it often happens that when the driver and the occupant open the doors on both sides, the vehicles (such as electric vehicles, motorcycles, taxis, trucks, bicycles, etc.) and pedestrians on both sides cannot dodge. Thereby the situation that collides with the opened car door not only causes damage to the vehicle, but also brings harm to the personal safety of the occupants and pedestrians on both sides, and seriously even causes the death of the person hit. For this type of safety accident, the reason i...

Problems solved by technology

However, this existing anti-collision solution based on radar or camera, etc., not only has blind spots, but is also easily affected by weather or ambient light. In rainy, foggy or dark conditions, the detection error of the sensor will increase. Large, the door anti-collision function is abnormal
