Lane Keeping Assist System (LKAS) Description - Overview

Lane Keeping Assist System (LKAS)

The LKAS uses the multipurpose camera to read the lane lines on both sides of the road. The multipurpose camera unit draws an imaginary line at the center between both lane lines, and lane keeping assist control is performed by assisting the steering so that the vehicle is guided along this imaginary line near the center of the lane.
The system gets suspended when the system determines that the driver is not holding the steering wheel for a certain period of time while LKAS is in operation.

LKAS Inoperative Road Conditions

LKAS does not operate in the following road conditions (LKAS is inoperative while LDW continues to operate).

In case one side of lane mark is temporary missing

LKAS will continue to work even when one side of the lane mark is missing temporarily such as an intersection or a junction.

Operation Conditions

System Operation Conditions	Operation under conditions where lane line recognition is possible on both sides (Lane line recognition may not be possible in bad weather, snow-covered roads, or areas with backlight).
