AI Technical Summary

Technical Problem

The prior art is difficult to change lanes quickly and accurately during driving, which increases traffic congestion and unsafe factors, especially in judging vehicle distances and inclement weather conditions.

Method used

By determining the driving intention of the current vehicle, we judge whether the lane change conditions are met based on the speed and distance of the front and rear vehicles, and judge whether the lane change can be safely changed based on the safe road change distance and vehicle speed stability coefficient, send a lane change request to the front and rear vehicles and receive permission After performing lane change.

Benefits of technology

Ensure the safety of the lane change process, avoid collisions with front and rear vehicles, and improve the driving experience, especially in special weather and when novice drivers change lanes.

Abstract

The invention relates to a lane changing assisting method and system, and belongs to the technical field of driving. The method comprises the steps that the driving intention of a current vehicle is determined; based on the current vehicle, a first front vehicle of the current vehicle, a second front vehicle of the current vehicle and a first rear vehicle of the current vehicle, whether the lane changing analysis condition is met or not is judged, the first front vehicle is the front vehicle of the current vehicle in the current lane, the second front vehicle is the front vehicle of the current vehicle in the lane changing direction, and the first rear vehicle is the rear vehicle of the current vehicle in the lane changing direction; under the condition that the condition of analyzing lane changing is met, whether the current vehicle meets the lane changing condition or not is judged according to the first distance of safe lane changing and the second distance of the current vehicle and the second preceding vehicle; and when it is determined that the current vehicle meets the lane changing condition and the current vehicle receives a lane changing permission response, the current vehicle performs lane changing. According to the method, the safety in the lane changing process is ensured, collision with front and rear vehicles is avoided, and the driving experience is improved.
