Overview
The
Lane Keeping System (LKS) has 2 functions, lane keeping aid and lane
keeping alert. The Lane Keeping System (LKS) utilizes the camera located
in the IPMA to detect

message center. The lane keeping aid assists the driver by
automatically providing steering torque to help the driver keep the
vehicle in the lane.
