The basic purpose of lane-keeping assist systems
(LKAS), one of the many safety features found on new cars today, is to keep you
and your passengers safe on motorways and dual carriageways by assisting you if
you accidently drift out of your lane.
Lane departure warning systems (LDWS) are devices that
warn the driver when the vehicle begins to veer past a white line without signaling
by vibrating, sounding, or providing a visual indication. The next step up from
that is lane-keeping assist technology, which can both warn the driver and move
the car back towards the middle of its lane.
How Lane Keeping Assist System operation?
Manufacturer-specific lane-keeping assistance systems
vary slightly, but they all typically function by employing a camera located
behind the rearview mirror to observe the lines on the road. The system can
warn the driver if the car is driving out of its lane without using an
indicator after utilizing the camera to determine where the automobile is in
respect to the lines on the road.
While some systems additionally include visible alerts
on the dashboard and sounds to bring attention to the possible issue, others
inform the driver by vibrating the steering wheel or the sides of the driver's
seat. If an indication is activated or the driver adjusts the car's line with
the steering, the alert will end.
If the driver doesn't recenter the car, lane-departure
assist can automatically correct the automobile by altering the steering or
braking on one side to change the direction of the vehicle. Because
lane-keeping assist is intended for highway driving, it will start working once
the car has reached a speed of 40 mph or more.
Many systems offer two different levels of help, such
as a gentle reminder to stay in your lane or an emergency mode that will offer
a harsher correction if it senses more immediate danger.
Issues With the Lane Keeping Assist System
When lane-keeping assist systems malfunction, the car
may feel unnaturally jerky when it brakes or pulls on the wheel to make the
necessary corrections. The feature may usually be changed to be less sensitive
or deactivated if it becomes too distracting. They can be overridden by
strongly steering against the adjustment. However, if you switch the car off
and back on again, it will frequently turn itself back on automatically.
Sometimes it is necessary or advantageous for drivers
to cross white lines without signaling on narrow or winding roadways. You might
be swerving to the side of the road to make room for an approaching tractor or
heavy-duty vehicle, or you might be trying to escape a pothole.
