Abstract

Map displaying device for a navigation system in a vehicle, the indication of the route from a starting point (SP) to a destination point (ZP) always being displayed independently of the actual position of the vehicle, and the covered route being visually differentiated from the route still to be driven.

Claims

1. A navigation system for a vehicle, comprising a map display device continuously displaying an a route from a starting point to a destination point independent of an actual position of the vehicle and displaying an already completed portion of the route in a visually different manner from a remaining portion of the route which is not yet completed.

2. Map displaying device according to claim 1, wherein the route between the starting point and the destination point is illustrated as a stringing-together of at least one individual destination, the course of the route being plotted as a directed arrow.

3. Map displaying device according to claim 1, wherein, in the event of a deviation of the actual position from the defined driving route, an originally computed driving route continues to be displayed in the navigation system, and the navigation system computes the optimal route from the actual location back to the originally computed driving route.

4. Map displaying device according to claim 1, wherein, the display of the driving route takes place without map data for navigation.

5. Map displaying device according to claim 2, wherein, the display of the driving route takes place without map data for navigation.

6. Map displaying device according to claim 3, wherein, the display of the driving route takes place without map data for navigation.

8. The method according to claim 2, wherein the route between the starting point and the destination point is illustrated as a stringing-together of at least one individual destination, the course of the route being plotted as a directed arrow.

11. The method according to claim 8, wherein, the display of the driving route takes place without map data for navigation.

7. A method of displaying a map for a vehicle navigation system, comprising the steps:

displaying an actual position of said vehicle;

displaying an indication of a route from a starting point to a destination point continuously and independent of said actual position of said vehicle; and

displaying a first portion of the route already completed by said vehicle is a visually different manner then a remaining portion of said route.

9. The method according to claim 7, wherein, in the event of a deviation of the actual position from the defined driving route, an originally computed driving route continues to be displayed in the navigation system, and the navigation system computes the optimal route from the actual location back to the originally computed driving route.

10. The method according to claim 7, wherein, the display of the driving route takes place without map data for navigation.

12. The method according to claim 9, wherein, the display of the driving route takes place without map data for navigation.
