Ford Fusion: Lane Keeping System / Lane Keeping System - Overview. Description and Operation
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
and track the road lane markings. The lane keeping alert detects
unintentional drifting toward the outside of the lane and alerts the
driver through steering wheel vibrations and a visual alert in the IPC
message center. The lane keeping aid assists the driver by
automatically providing steering torque to help the driver keep the
vehicle in the lane.
