A method for warning a driver of a motor vehicle against a speed detection camera in surroundings of the motor vehicle by a navigation device, a computer prog

Abstract

Navigation device 12 onboard a motor vehicle 10 receives a map 20 (via receiving device 24) with a position P1 of a speed detection camera 16 in its surroundings 14. It determines a current vehicle position P2 using its position detection device 26 and generates and presents a warning signal for the driver via its electronic computing device 28 depending on the two positions P1 and P2. The warning signal (e.g. an icon on a display or an audio signal) is continuously generated after the vehicle passes the speed camera position P1 and its presentation is ended depending on a current speed limit. A degree of strength of the warning signal gradually decreases from the speed camera position P1 to a position (P3,Fig.4) where the warning ends according to the speed limit and the distance between the speed camera and the vehicle. If the speed limit is 30km / h or 100 km / h, the warning may end after 150 meters (42,Fig.4) or 500 meters (44,Fig.4) respectively.
