Abstract
A vehicle navigation system may include an antenna, e.g. a GPS antenna, an output for providing guide advice to the vehicle driver and including a display, a memory encompassing a navigation database with electronic maps stored within, and an electronic controller. The system is capable of detecting the global position of the vehicle on the basis of the electromagnetic waves received by the antenna, associating the global position to the exact road position of the vehicle by comparison with the electronic maps and providing pictorial guide advice to the vehicle driver according to the road position via the display. The system may include a digital camera installed on the vehicle and able to record digital pictures of the outside and to provide the digital pictures to the electronic controller. The pictures are displayed via the display, and pictorial guide advice, e.g. directional arrows, are overprinted to the displayed pictures.

32. A navigation method for guiding a driver of a vehicle with a navigation system including an antenna, an associated controller, an associated memory, an associated display and an associated camera, the method comprising:
-
receiving navigation signals via the antenna and detecting a global position of the vehicle with the controller; comparing the global position with road maps stored in the memory to define the road position of the vehicle with respect to the road maps; capturing an image of a view observable by the vehicle driver with the camera; and displaying the image on the display along with guidance for the vehicle driver according to the road position of the vehicle defined with reference to the road maps. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40)
