Lane Departure warning
Lane departure warning tells you when your vehicle is ready to deviate out of its lane and urges you to return to it. That’s the core concept, but there are now numerous versions of the technology available, including ones that react and steer away from the lane edge, as well as ones that proactively keep the car centered. All types of lane departure warnings use a low-cost camera installed in the windshield near the rearview mirror that continuously monitors the road’s striped and solid lane lines. It is a part of the circle of safety, which includes the three most popular and useful driver aids: Front (adaptive cruise control and forward-collision warning), side (lane departure warning), and rear side protection (blind spot detection). Technology innovation has reduced the cost of all three components to less than $1,000 on many vehicles. Are you considering purchasing a vehicle with a lane departure warning? Here’s what you should know.
Lane departure warning
This is the first version. It is merely a warning. When you allow the automobile to drift close to, onto, or over a lane marking, the car warns you. As the driver, you must rectify the situation by directing the vehicle back to the center of the lane. It does not operate if there are no lane lines on the road. If your state waits until the lane markings have faded before repainting, it may not work as well. Lane indicating dots might be difficult to locate, especially if their color has faded. If it’s raining or snowing, the camera may struggle as well. The lane departure warning system is designed to not warn you if your turn signal is turned on or (in some vehicles) if you hit the brakes.
Lane centering assist
As long as you believe in technology, this is the best and most recent system. It is a completely proactive system. Lane centering assist attempts to maintain the vehicle centered in the current lane at all times. It works as long as the car detects your hands on the steering wheel, and as long as the turns aren’t too sharp. You have the beginnings of what some would call self-driving if you have lane-centering aid and adaptive cruise control. If you speed along the road, unknowingly staring at a music playlist or skimming a full-screen text, the combination is enough to save you from inattentiveness. Lane centering help isn’t as common as the other two.
Lane keep assist
This is useful if you have allowed the automobile to drift too far. If the vehicle then drifts away from the lane marking, the driver must realign the vehicle in the lane. This system helps the car to drift back into the lane safely if certain conditions are fulfilled. This feature is very helpful in preventing a crash on the road. Lane-keeping system, lane assist, side assist (Audi), lane departure alert with steering aid (Toyota), or lane departure prevention are other names for it (LDP has sometimes applied also to lane centering assist).
Other automobiles vibrate the steering wheel or the seat cushion. The vibration is unlike any other vibration the car experiences when driving on a rough or gravelly road, or when the anti-lock brakes engage. Seat cushion feedback might vibrate exclusively on the left or right side of the car, directing your attention to the troublesome side. In general, Asian vehicles are more likely to employ audio warnings, European vehicles are more likely to use haptic input, and American vehicles use a combination of both (but not both on the same car). The choice between audible and haptic isn’t an option. You must decide whether one or the other is so vital that you will switch from one brand to another.
