44 The LTA system is comprised of the lane departure alert function, the steering
assist function, the lane centering function, and the vehicle sway warning function.
The in-vehicle camera detects the visible white and yellow lane markers in front the
vehicle and the vehicle’s position on the road. If the vehicle starts to unintentionally
deviate from its lane when the LTA system is on, the lane departure alert function
alerts the driver with an audio and visual alert. When the steering assist function
is enabled, if the system determines that the vehicle is on a path to unintentionally
depart from its lane, the system may provide small corrective steering inputs to
the steering wheel for a short period of time to help keep the vehicle in its lane.
Additionally, when enabled, the lane centering function will automatically provide
assistance to help keep the vehicle in the center of the lane when Full-Speed DRCC
is set. If the vehicle repeatedly deviates from the lane, the vehicle drifts within the
lane due to inattention, or the driver abruptly operates the steering wheel after an
inattentive period, when enabled, the vehicle sway warning function alerts the driver
with an audio and visual alert, urging them to take a break.
