This paper describes a method of detecting unintentional lane departure of a vehicle due to driver's carelessness or fatigue, thus preventing tragic traffic accidents. The current lateral position of the vehicle and its orientation are calculated from lane markings obtained by a CCD camera, and an urgency index is calculated. If any deviation beyond a preset urgency value is detected, with no lane change signal, a warning alarm is issued and the vehicle is directed toward the center of the lane by adjusting the current steering angle. For the covering abstract see IRRD E102946.
