Keeping method and device for vehicle lane

Abstract

The invention provides a keeping method and device for a vehicle lane. The keeping method comprises the following steps that posture information and locating information of a vehicle are obtained through at least two high-accuracy antennas; a predicted location of the vehicle after a preset period is obtained according to the posture information and the locating information; and it is confirmed that the predicted location is not in the lane, and lane keeping processing is conducted on the vehicle according to the predicted location. According to the keeping method and device for the vehicle lane, the location where the vehicle is located is predicted after a certain time through the high-accuracy antennas, the fact that lane keeping processing is conducted before the vehicle deviates from the lane is realized, the defect that lane keeping processing is conducted after the vehicle deviates from the lane in the prior art is overcome, the vehicle is effectively prevented from deviating from the lane, and traffic accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a method and device for maintaining vehicle lanes. Background technique [0002] With the continuous development of economy and transportation, automobiles have become an indispensable means of transportation for people. However, with the continuous improvement of the utilization rate of automobiles, the traffic accident rate also shows an increasing trend year by year. According to statistics, among all motor vehicle accidents, traffic accidents caused by lane departure account for 20% of all traffic accidents. Thirty-seven percent. It can be seen from this data that lane departure accidents have seriously affected people's life and property safety. [0003] In the prior art, the lane keeping method generally includes the following steps: After receiving the vehicle's position information, map and road information, adding the vehicle's position information to the map, and det...

AI Technical Summary

Problems solved by technology

[0004] Therefore, there are at least the following technical defects in the prior art: only after the vehicle completely deviates from the lane, for example, after the vehicle presses to the lane line of the designated lane, will the vehicle be prompted to have deviated from the lane, and at this time the vehicle has deviated from the original lane, making The adjustment time of the vehicle is late, which is likely to cause traffic accidents
