Lane Keep Assist System
(LKA)
The Lane Keep Assist System can
recognize lane lines, pedestrians, curbs,
front/rear incoming vehicles, and calculate
the distance from the vehicle to the left/right
lane line and front/rear incoming vehicles
via front camera and rear side medium-
range radar when the vehicle speed is high
than 65 km/h. When the vehicle deviates
from the lane or is about to collide with
pedestrians, vehicles in the adjacent lane,
the system will give a corrective assist force
to prevent the lane deviation, mitigate or
avoid collision, or remind the driver to keep
the vehicle in the lane. The Lane Keep
Assist System consists of Lane Keep Assist,
lane departure warning, and lane keeping
emergency assist.
When the vehicle is powered on, the
Lane Keep Assist System will start
self-check, and the system function is not
available at this stage.
Make sure the front camera surface is
clean. Dirty front camera, bad weather
conditions and fading lane lines, may affect
the performance of Lane Keep Assist
System.
The Lane Keep Assist System is only
suitable for use on expressways and
main urban roads, and the driver needs to
concentrate on driving the vehicle. When
using Lane Keep Assist, you should hold the
steering wheel and keep an eye on the road
and surrounding traffic. Do not use this
feature on city streets, construction areas,
narrow roads, or road sections where
cyclists or pedestrians may be present. It is
strictly forbidden to rely on the Lane Keep
Assist System to determine the appropriate
driving route. Be sure to take measures at
any time and in a timely manner. Failure to
follow these instructions can result in
serious property damage and personal
injuries or even death.
When the electronic stability control
system (ESC) is off, the lane
departure prevention (LDP) and emergency
Lane Keep Assist (ELKA) cannot work.
Function Types
Lane Departure Warning (LDW)
Lane Departure Warning (LDW) warns the
driver when the vehicle deviates from the
lane unconsciously. Unconscious lane
departure includes the already happened
lane departure and the imminent lane
departure.
Lane departure prevention (LDP)
As for lane departure prevention (LDP),
when the vehicle approaches lane lines and
there is a risk of deviation, the system will
assist the driver to control the vehicle back
to the lane by applying torque to steering
wheel.
Emergency Lane Keep Assist (ELKA)
Emergency Lane Keep Assist (ELKA) can
help the vehicle back to its own lane in the
following situations:
• The vehicle is about to rush out of the
road or collide with the edge of roads.
• Unintentional deviation from the lane and
there may be a collision with the opposite
vehicle.
• Unintentional deviation from the lane and
there may be a collision with the vehicle
