EP0811961

Method for conditioning routing information, to be transmitted to
the driver of a vehicle
Advice on the reading of patent specifications:
Patented idea: Ahead of a number of consecutive road junctions a navigation system produces anticipatory notices like for example "turn right third street" instead of signalling the turn not before approaching the third road junction. Main claim: When the distance to the road junction is shortening to a specified minimum distance: verify if there are further junctions in the same direction and take them – if necessary – into account in the notices that are produced. Further claims:
Description: The patent specification documents the insight that occasionally the distances between road junctions occurring one after the other are closer than the accuracy of the routing system and that the resulting navigation problem can be solved by pooling several junctions with one notice. Everyday parallel: In a car the co-driver reads the street names and compares them to a street map (routing system). As soon as the car approaches several consecutive road junctions (minimum distance) the co-driver (voice message) says to the driver: "Turn right at the third road junction." Example for patent infringements: Every car navigation system
