Lane Departure Warning System (LDW)
LDW wil warn the driver if he or she is on the verge of inadvertently drifting out of the lane. Using a CMOS Camera and an image processing algorithm, this driver assistance system registers the course of the lane in relation to the vehicle. The system "sees", as it were, the course of the road and where the car is going. If the warning algorithm detects an imminent leaving of the current driving lane, the system warns the driver with haptic, kinestatic, or acoustical feedback. Possible warning alerts can be a trembling in the steering wheel, a vibrating seat or a virtual washboard sound (a noise people recognize as generated by driving over a lane marker at highway construction sites).
