Method for automatically predicting passage on red light intersection with assist of automobile

Abstract

The invention discloses a method for automatically predicting passage on a red light intersection with the assist of an automobile, and relates to the technical field of automobile auxiliary systems.An automobile controller compares time of a vehicle passing through a traffic light intersection and time of a vehicle in front of the vehicle passing through the traffic light intersection with remaining time information on a red signal light and green signal light on traffic lights to predict the situation of the vehicle capable of passing through the traffic light intersection in advance, thereby improving the driving safety; and the vehicle can further detect the traffic flow situation of a current traffic light intersection to acquire the traffic flow congestion situation of the intersection in various directions and acquire a driving scheme of a next traffic intersection of a plan route in advance. The method for automatically predicting the passage of the red light intersection withthe assist of the automobile has the advantages that not only can the safety of the intersection passing be improved, but also the congestion intersection can be avoided in advance.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary systems, in particular to an automobile auxiliary method for automatically predicting traffic at a red light intersection. Background technique [0002] The safety performance of automobiles is more and more paid attention to by people. Existing car drivers can only see the remaining time of red lights or green lights clearly when passing through red light intersections. At this time, if the driver's judgment is wrong Accurate, you may wear a red light, and for novice drivers, if you brake suddenly at an intersection, it is easy to cause a traffic accident. [0003] Vehicles in the state of autonomous driving currently rely on cameras to capture the status of traffic lights when passing through intersections, and only when they find that the signal lights are flickering can they make a driving plan whether to speed up or slow down to wait. Not to mention predicting in advance, it is ...

[0002] The safety performance of automobiles is more and more paid attention to by people. Existing car drivers can only see the remaining time of red lights or green lights clearly when passing through red light intersections. At this time, if the driver's judgment is wrong If it is accurate, you may wear a red light, and for novice drivers, if you brake suddenly at the intersection, it is easy to cause traffic accidents

[0003] Vehicles in the state of autonomous driving currently rely on cameras to capture the status of traffic lights when passing through intersections, and only when they find that the signal lights are flickering can they make a driving plan whether to speed up or slow down to wait. Not to mention predicting in advance, it is impossible to establish the best automatic driving plan
