Lane Departure Warning LDW or LKA
There are two versions of Lane assistance:
- LDW - Lane Departure Warning - alerts the driver with an acoustic signal or vibration in the steering wheel.
- LKA - Lane Keeping Aid(Lane Keeping Aid) - steers the car back into its lane and/or alerts the driver with an acoustic signal or vibration in the steering wheel.
The car is supplied with one of these two systems - market and engine alternative determine which of the systems the car is equipped with.
In the event of uncertainty whether the car has LDW or LKA:
- Open the menu system MY CAR and locate Driver support system - which specifies Lane Departure Warning if the car has LDW or Lane Keeping Aid for LKA.
Principle for LDW
(The figure is schematic - not model specific.)
A camera reads the side lines of the road/lane.
Warning with steering wheel vibration
The figure shows 3 vibrations when the side line is crossed.
If the car crosses one of the side lines the driver is alerted with an acoustic signal or vibration in the steering wheel. Steering wheel vibration varies - the longer the time for which the car has crossed the side line, the longer the vibration.
The driver is only warned once each time the wheels cross a line. So there is no acoustic alarm when there is a line between the car's wheels.
Lane assistance is merely a driver aid and does not engage in all driving situations or traffic, weather or road conditions.
The driver always bears ultimate responsibility for ensuring that the vehicle is driven safely and that applicable laws and road traffic regulations are followed.
