INDICATING DIRECTIONS TO DESTINATION AND INTERMEDIATE LOCATIONS IN VEHICLE NAVIGATION SYSTEMS
First Claim
1. A vehicle navigation system comprising:
- a plurality of sensors for generating location data relating to a vehicle location;
a memory for storing map data in a map database;
a display; and
a processor operable to;
determine the vehicle location using the location data, and where the location data do not correspond to the map data, generate a directional indicator on the display which indicates a first location corresponding to the map data instead of a specified destination.

Abstract
The present invention provides a computer implemented method and apparatus for providing a directional arrow to intermediate locations to aid a user of a vehicle navigation system. According to one aspect of the present invention, a vehicle navigation system is provided and includes a processor configured to determiner the vehicle location from location data generated by a plurality of sensors. Where the location data does not correspond to map data in a map database, a directional indicator is generated on the display to indicate a first location corresponding to the map data. In one embodiment, the first location corresponds to a road segment in the map database nearest the vehicle location. In another embodiment, the processor is configured to identify an intermediate location on the route and generate a directional indicator on the display which indicates the direction to the intermediate location. In yet another embodiment, the processor is configured to automatically select an appropriate intermediate location in accordance with the measured angle between the vehicle heading and the intermediate location.
