US 12,703,360 B2 · Lane departure monitoring methods and apparatuses

Abstract

A lane departure monitoring method includes (i) calculating the lateral offset of the vehicle at the reaction time, (ii) predicting whether the vehicle will depart from the lane under the control of an autonomous or assisted driving system according to the calculated lateral offset, (iii) after predicting that the vehicle will depart from the lane, calculating the maximum lateral offset of the vehicle relative to the left lane line or the right lane line based on the lateral acceleration limit value and the lateral acceleration gradient limit value, (iv) again predicting whether the autonomous driving system or assisted driving system can control the vehicle within the lane according to the maximum lateral offset, and (v) based on the result of the second prediction, decelerating the vehicle and/or sending an alert signal to the driver. Also disclosed is a lane departure monitoring apparatus, computer-readable storage media, computer program products, and a domain controller for a vehicle.
