Device and method for selecting lanes at traffic light intersections

Abstract

The invention discloses a device for selecting lanes at traffic light intersections of automobiles, which belongs to the field of automobiles and includes a storage unit, a position determination unit, a traffic signal light identification unit, a calculation unit, a lane analysis unit, and a lane selection unit. The lane selection unit includes a safe lane change judgment system, Statistics system, screening system, range finder, speedometer, vehicle type recognition system and license plate recognition system. Utilize the device for selecting lanes at traffic light intersections provided by the present invention, when the light is green, select the lane with the least number of corresponding vehicles or the overall faster speed, so that the car can drive through the stop line as soon as possible before the end of the green light, and pass through the traffic light intersection as soon as possible; When the lights are on, choose the lane with the least number of vehicles or the lane with the least time from the waiting vehicles to pass the stop line. After the car enters, the car can pass the stop line and pass the traffic light intersection in the shortest time.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a device for selecting a lane at an automobile traffic light intersection and a method for using the same. Background technique [0002] With the continuous development of society, the number of cars is increasing, especially during rush hours, there will be a lot of cars passing through traffic light intersections or waiting for green lights. There are a lot of cars driving or some driving very slowly. If the car enters such a lane, it will take a long time for the car to pass through the traffic light, and even when the red light is on, the car does not pass the stop line. Can wait for the green light to pass; if there are more vehicles waiting for the green light in some lanes or more cars starting slowly, if the car enters this lane, it is easy to cause the car to fail to pass the stop line at the end of the next green light, or even have to pass the stop line. Wait mo...

Problems solved by technology

[0002] With the continuous development of society, the number of cars is increasing, especially during rush hours, there will be a lot of cars passing through traffic light intersections or waiting for green lights. There are a lot of cars driving or some driving very slowly. If the car enters such a lane, it will take a long time for the car to pass through the traffic light, and even when the red light is on, the car does not pass the stop line. Can wait for the green light to pass; if there are more vehicles waiting for the green light in some lanes or more cars starting slowly, if the car enters this lane, it is easy to cause the car to fail to pass the stop line at the end of the next green light, or even have to pass the stop line. Wait for more traffic lights before passing the stop line at this traffic light intersection

Both of the above situations will cause the vehicle to drive slowly and even waste more time

In the prior art, there is a function of prompting how long to wait before passing the stop line according to the road conditions of the vehicle and the duration of the traffic light, but this does not make much sense in actual driving, because if you can pass, you can pass, if you can’t pass, you have to wait, for the waiting time At least, it is of practical significance to choose the shortest time to pass the stop line
