Problems solved by technology

[0004] Patent No. CN201510946454.2 discloses a system and method based on navigation to assist drivers in judging passing traffic light intersections. This invention can only remind the driver of the time required to reach the traffic light intersection. In real life, it is not necessary to turn on the navigation system every time you drive. If you do not turn on the navigation, this invention cannot remind the driver

Embodiment Construction

[0022] Preferred embodiments of the present invention are described in detail below:

[0023] Obtain the vehicle's position and driving direction information in real time through the positioning module and compare it with the traffic light intersection database to calculate the distance between the vehicle and the first traffic light intersection in the driving direction. When the distance is 100 meters, obtain the vehicle's speed through the positioning module, and the vehicle's speed Both the speed and the driving direction of the vehicle are obtained by using the positioning module. Of course, they can also be obtained by the vehicle speed sensor. This is a known technology. Compare the database to know which type of intersection this lane belongs to. The lane types include U-turn lanes, left-turn lanes, straight lanes, right-turn lanes, and combinations of these types. After that, the camera of the recognition module takes pictures and recognizes the driving direction The ...

Abstract

The invention, which belongs to the field of intelligent driving, particularly relates to a method for assisting a driver in crossing a traffic light. The invention provides a method of determining whether a driver can drive the vehicle to pass the traffic light within green light time. Accidents occur frequently at the traffic light intersection because drivers can not determine whether the motorvehicles can pass the intersections successfully within the residual green light time accurately. Many drivers notice that the traffic lights become red light states when arriving at the intersections but can not stop the vehicles timely due to the high speeds, so that the vehicles collide with vehicles from the other sides; and if the vehicle drivers can be informed of the result of determiningwhether the vehicles can pass traffic lights successfully in advance before arriving at the traffic light intersections, the drivers can be assisted well.

Description

technical field [0001] The invention belongs to the field of intelligent driving, in particular to a method for assisting a driver to cross a traffic light intersection. Background technique [0002] Traffic light intersections are the places where motor vehicles have the most traffic accidents. Most of them are because drivers cannot accurately judge whether motor vehicles can pass through the intersections within the remaining time of the green lights. Many drivers often find that they have turned into red lights when they first arrive at the intersection. The speed of the vehicle is too high to brake in time, thus causing a collision with the vehicle on the other side. If the vehicle owner can be notified in advance whether the vehicle can pass the traffic light before the vehicle reaches the traffic light intersection, it will be of great help to the driver. The obtained results can be input to the automatic driving system for analysis by the automatic driving system. ...
