Abstract

The navigation system includes a route preview device, simultaneously displaying a map representation (21) of the route and guiding information (23). The information is superimposed on the map representation in connection with the point of the route to which the above apply. Rules for priority of display of guiding information and for the direction of display thereof are also defined.

Claims

1. An onboard navigation system (1), comprising cartographic data (40), means of input (30) of at least one destination, means of calculation of a route (11) between an origin point and said destination, means of determination of guidance information (13) on this route, and means of display (20), characterized in that the system comprises a device for previewing (14) said route simultaneously displaying a cartographic representation (21) of the route, and guidance information (23), said information being superimposed on the cartographic representation in relation to the point of the route to which it will be applicable.

2. The navigation system as claimed in claim 1, characterized in that the route (22) is made up of hierarchized stretches of road, and in that the previewing device (14) comprises means of determination of a scale of display of the cartographic representation and means of selection

of the hierarchical level of the stretches of road to be displayed as a function of said scale of representation and,

of the guidance information displayed as a function of the hierarchical level of said stretches.

3. The navigation system as claimed in claim 2, characterized in that, in case of conflict of display between several items of guidance information (23a, 23b), the guidance information item relating to the stretch of highest hierarchical level will be displayed by priority.

4. The navigation system as claimed claim 1, characterized in that the guidance information is displayed such as it will be presented while traveling the route, whatever the orientation of the cartographic representation.

5. The navigation system as claimed claim 2, characterized in that the guidance information is displayed such as it will be presented while traveling the route, whatever the orientation of the cartographic representation.

6. The navigation system as claimed claim 3, characterized in that the guidance information is displayed such as it will be presented while traveling the route, whatever the orientation of the cartographic representation.
