Routing display for navigation systems
First Claim
1. A method for showing routing information from a navigation system for a road vehicle on an electro-optical display driven by a routing computer, the method comprising the steps of:
- displaying a symbol for a direction of current travel and a symbol for a direction to be taken after a turn-off point relative to the direction of current travel;
determining a distance from the vehicle to the turn-off point; and
changing the size of the symbol for the direction of current travel relative to the size of the symbol for the direction to be taken after the turn-off point in response to the distance to the turn-off point while maintaining the same view of the symbols including changing the size and position of the symbol for the direction to be taken after the turn-off point in response to the distance to the turn-off point, and maintaining the size and position of the symbol for the direction of current travel independent of the distance to the turn-off point.

Abstract
A routing display for a navigation system in a road vehicle in the form of an electro-optical display can be driven by a routing computer and uses symbols to display a direction of current travel and a direction which is to be taken after a turn-off point relative to one another. The sizes of the two symbols relative to one another is changed such that the relative size of the symbol marking the direction which is to be taken after the turn-off point increases as the turn-off point is approached. Accordingly, when the driver looks at the routing display, he is given the visual impression that he is approaching the turn-off point.

2. A routing display for a navigation system in a road vehicle, said routing display comprising:
-
an electro-optical display device drivable by a routing computer;
means for displaying, on said display device, a symbol for a direction of current travel and a symbol for a direction to be taken after a turn-off point relative to said direction of current travel, said means for displaying comprising means for displaying the symbols in isolation from a depiction of roads corresponding to the direction of current travel and the direction to be taken after the turn-off point; and
means for changing the size of the symbol for the direction of current travel relative to the size of the symbol for the direction to be taken after the turn-off point in response to a distance from the vehicle to the turn-off point while maintaining the same view of the symbols such that the relative size of the symbol for the direction to be taken after the turn-off point increases as the distance of the vehicle to the turn-off point decreases, and such that the distance to the turn-off point is indicated exclusively by the change in the relative sizes of the symbols. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
