Lane-keeping assist (LKA)

This term is part of the following categories: Safety, Technology, Sensors and Vehicle system.

Version: 5.0, Release date: April 2023

Definition: Vehicle system that uses cameras or other inputs and systematic controls to direct the vehicle away from the edges of the driven lane.

NOTE Unlike lane-centring, this system operates exceptionally when it detects that the vehicle is about to depart from the driven lane. Some systems allow a degree of line crossing before directing the vehicle back into the lane from which it is departing. Current systems rely on lane markings of sufficient quality and visibility to support the function. The system can be cancelled by use of the turn signals.
