Problems solved by technology

As mentioned above, since existing LFA systems only consider vehicle speed when calculating the target look-ahead distance, the vehicle uses the same look-ahead distance no matter how far the vehicle deviates from the target line, resulting in an increased approach angle

Abstract

The invention provides a lane keeping assist apparatus and a control method thereof. The lane keeping assist device includes: a camera that captures an image in front of a vehicle; and a processor receiving the front image from the camera. The processor acquires lane line information from the front image, calculates a vehicle offset based on the lane line information, variably sets a target foresight distance according to whether the vehicle offset is greater than a threshold, and performs lane keeping assist control using the target foresight distance.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to Korean Patent Application No. 10-2020-0183846 filed in the Korean Intellectual Property Office on December 24, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a lane following assist (LFA) device and a control method thereof. Background technique [0004] The Lane Keeping Assist (LFA) system assists the vehicle in identifying lane lines and staying centered in the lane. The LFA system sets a target foresight distance proportional to the vehicle speed on the target path, and calculates the target rotation radius to a point according to the set target foresight distance. As mentioned above, since existing LFA systems only consider vehicle speed when calculating the target forward looking distance, the vehicle uses the same forward looking distance regardless of how far the vehicle deviates from the targ...
