Intelligent anti-collision early warning method for enabling motor vehicle to turn right to pass through non-motorized vehicle lane

Abstract

The invention discloses an intelligent anti-collision early warning method for enabling a motor vehicle to turn right to pass through a non-motorized vehicle lane. According to the method of the invention, the speed and position of a non-motor vehicle are detected in real time according to a radar velocimeter in a real-time detection module arranged on a non-motor vehicle lane; time when the non-motor vehicle arrives at a conflict area is determined through calculation and is compared with time when a motor vehicle passes through the conflict area; the right of way of the conflict area is judged; a display device is made to display an accurate passing signal; and therefore, collision between the motor vehicle and the non-motor vehicle is reduced. With the method adopted, the conflict influence of a right-turning motor vehicle and a non-motor vehicle is fundamentally eliminated, so that traffic conflicts and accidents caused by the visual blind area and misjudgment of the driver of themotor vehicle are reduced. The method is not influenced by the shielding of a motor vehicle and non-motor vehicle isolation green belt. With the method adopted, the defect of high cost caused by the installation of all vehicles is avoided.

Description

technical field [0001] The invention designs an intelligent anti-collision early warning method for a motor vehicle turning right and crossing a non-motor vehicle lane, and belongs to the technical field of intelligent traffic signal control Background technique [0002] The problem to be solved in the present invention is that when a motor vehicle crosses a non-motor vehicle lane, it is easy to collide with a non-motor vehicle coming from the right rear, but there is no corresponding prior art for solving this problem, and there are only several items that solve similar problems technology. These include: [0003] 1. Research on Conflict between Motor Vehicles, Pedestrians and Non-Motor Vehicles Turning Right at Signalized Intersections [0004] 2. Analysis of conflict game behavior between motor vehicles and non-motor vehicles turning right [0005] Above two kinds of technologies all are researching and analyzing the conflict between motor vehicles and non-motor vehicl...

Problems solved by technology

[0009] For these three kinds of existing technologies, all are installed on the car body, and when non-motor vehicle and motor vehicle short-distance conflict are about to collide, send early warning, there are following deficiencies: (1) because detection distance is shorter, can only avoid collision to occur , cannot eliminate the impact of conflict on traffic flow operation; (2) When there is an isolated green belt between the motor vehicle lane and the non-motor vehicle lane, it is difficult for the above-mentioned system to detect the non-motor vehicle coming from behind, causing the alarm to fail; (3) Due to the high cost, the above technology is difficult to apply to all cars, so it is not universal
