Abstract

The invention discloses a lane keeping method which comprises the following steps: acquiring driving information of a vehicle, and acquiring deviation information of the vehicle according to the driving information; obtaining a lane center line of the current period of the vehicle, and obtaining a target lane center line of the vehicle according to the deviation information and the lane center line of the current period; the current position of the vehicle is obtained, a return correction path is generated according to the center line of the target lane and the current position of the vehicle, the vehicle is controlled to run according to the return correction path, and the return correction path is a curve with the curvature continuously changing. The invention further discloses a system, equipment and a computer readable storage medium. By means of the method, large transverse acceleration is avoided, the risk of sideslip in high-speed driving is reduced, and good driving experience is brought to a driver.

Description

technical field [0001] The present invention relates to the field of vehicle control, in particular to a lane keeping method, system, device and computer-readable storage medium. Background technique [0002] At present, with the popularity of intelligent assistance systems, Lane Keeping Assist (LKA), as a part of intelligent driving assistance systems, is also receiving more and more attention. In the current lane keeping assist system, the design idea of ​​the lane keeping assist system can be divided into two types. One kind of design idea is to apply a corner torque to the steering system of the vehicle when the vehicle is about to drive out of the lane, so that the vehicle returns Get into this lane. The other uses the centerline of the lane as the expected driving path of the vehicle. When the vehicle deviates from the centerline of the lane, the vehicle is controlled to return to the centerline of the lane so as to keep the vehicle driving in the lane. The design of ...
