AI Technical Summary
Technical Problem
Consecutive lane departure warnings from Lane Trace Assist (LTA) and Lane Departure Alert (LDA) controls can be annoying for drivers, as they occur simultaneously when the vehicle deviates from its lane.
Method used
A lane departure warning system that prioritizes Lane Departure Alert (LDA) steering control over Lane Trace Assist (LTA) warnings, suppressing the occurrence of multiple warnings by initiating LDA steering control before LTA warnings are issued, thereby preventing vehicle deviation.
Benefits of technology
Effectively suppresses the consecutive occurrence of lane departure warnings, enhancing driver comfort and improving vehicle stability by prioritizing LDA steering control during Lane Trace Assist operations.

Abstract
This prevents two types of lane departure warnings from occurring consecutively. [Solution] A lane departure warning device that issues a warning when a vehicle deviates from or is about to deviate from its lane, comprising: an LTA control unit that determines whether there is a possibility of the vehicle deviating from its lane while lane keeping control is being performed to keep the vehicle within the lane, and if it determines that there is a possibility of deviation, it issues a first departure warning; an LDA control unit that determines whether there is a possibility of the vehicle deviating from its lane while the vehicle is in motion, and if it determines that there is a possibility of deviation, it issues steering control to suppress the vehicle's departure from its lane and a second departure warning; and an LDA priority processing unit that, while lane keeping control is being performed, prioritizes the steering control and / or the second departure warning by the LDA control unit over the first departure warning by the LTA control unit.
