How Lane Departure Warning Systems Save Your Life

Imagine you are driving home after a long work day. You feel a little tired. You are looking forward to arriving home and lying on your comfortable bed.Your attention begins to wander from the long stretch of highway you're traveling. Suddenly, an alarm startles you awake, and you see the lane-departure warning lights flashing on your dash. You adjust your course just in time to avoid running into the median. Your car’s lane departure warning system has spared you injury, damage to your vehicle, and possibly your life.

A lane departure warning system, or LDW, usually uses a camera to track the lanes on the road. Alternatively, some systems may use either lasers or infrared sensors to detect these lanes, but cameras are much more common. Usually, the camera is mounted on top of the windshield, though some other models exist in which it is installed elsewhere.

As you drive, the camera watches the road, and software is used to analyze the visual data, converting it into patterns that the computer system can recognize. This way, the system is able to watch the lanes and detect if you are getting too close to the edge.

When you are about to leave your lane, the system will give you a warning signal, usually an audible alarm and flashing signal lights on your dash, though there are some systems that will also vibrate the steering wheel or seat to get your attention in time to take corrective action.Some systems will take action for you. These are known as lane keeping systems (LKS). They will use either brake pressure on specific wheels or your power steering to keep you in the lane if you don't react in time yourself.
