AI Technical Summary

Technical Problem

In existing technologies, intelligent driving systems lack effective monitoring and verification schemes when the vehicle is centered on its trajectory, which may cause the vehicle to deviate from the lane and increase safety risks, especially when the user cannot take over the vehicle in time during L3 autonomous driving.

Method used

By acquiring vehicle trajectory information, speed information, and road images, feature points of the left and right lane lines are extracted, curve fitting is performed, and the relative deviations of trajectory, position, and heading are calculated for centering verification.

Benefits of technology

It achieves accurate calibration of centering, ensuring that the vehicle travels normally along the center line of the lane, reducing the risk of collision with adjacent vehicles or obstacles, and improving driving safety.

Abstract

The application provides a centering driving verification method and system, electronic equipment and storage medium. The centering driving verification method comprises the following steps: acquiring driving track information, vehicle speed information and a current road image of a lane where a vehicle to be controlled is located; extracting left and right lane line feature points in the current road image; performing curve fitting on the left and right lane line feature points respectively to obtain left and right lane line equations; performing curve fitting based on the driving track information to obtain a driving track equation; determining a track relative deviation amount, a position relative deviation amount and a heading relative deviation amount according to the left and right lane line equations, the driving track equation and the vehicle speed information; and performing centering driving verification based on the track relative deviation amount, the position relative deviation amount and the heading relative deviation amount.
