Abstract
Method and apparatus (2) of a vehicle for alerting a driver of a vehicle when the vehicle deviates from a predefined driving area in a lane. The apparatus includes an image display unit (6) and a control unit (5) connected to each other to enable the apparatus to provide a visual warning via the image display unit when the vehicle is outside the predefined driving area and where the visual warning is displayed in the form of a solid or broken line on the side of the image display unit (6) that corresponds to the side of the vehicle where the deviation occurs.

An apparatus for a vehicle for alerting a driver of the vehicle when the vehicle deviates from a predefined driving area in a lane, the apparatus comprising:
- an image display unit (6) connected to a control unit (5) that together provide a visual warning (7) on the image display unit (6) when the vehicle is outside the predefined driving area, the visual warning (7) taking the form of one of (i) a solid and (ii) a broken line at the side of the image display unit (6) that corresponds to the side of the vehicle toward which the deviation is occurring;
- wherein the visual warning (7) is moved sideways in proportion to the size of the deviation.
A method for alerting a driver of a vehicle when the vehicle deviates from a predefined driving area in a driving lane, said method comprising:
- detecting the limits of the driving lane and identifying the position of the vehicle in the driving lane;
- comparing the position of the vehicle with the detected driving area;
- and
- giving a visual warning to the driver when the vehicle is outside the predefined driving area, via an image display unit, by means of a warning mark in the form of a solid or broken line on the side of the image display unit that corresponds to the side of the vehicle where the deviation occurs;
- wherein the position of the warning mark is proportional to the distance of the vehicle from the edge of the driving lane.
