NAVIGATION APPARATUS USED-IN VEHICLE
First Claim
1. Apparatus for generating supplementary information for a digital map, the supplementary information representing suitability of road use according to vehicle category, the apparatus comprising a processing resource configured to:
- (a) receive trip information representing sessions of logged journeys from a plurality of navigation devices, each session of a logged journey including vehicle category information in respect of a vehicle making the logged journey,(b) analyse the vehicle category information to identify at least one session corresponding to a vehicle category of interest, the vehicle category of interest including at least one selected from;
a goods-vehicle;
a bus;
a car+caravan combination;
a vehicle exceeding a predetermined weight threshold;
a vehicle exceeding a predetermined width threshold;
a vehicle exceeding a predetermined height threshold;
a vehicle exceeding a predetermined length threshold;
a vehicle carrying predetermined hazardous material;
(c) analyse the trip information corresponding to at least one vehicle category of interest, to identify a route or route portion used by the vehicle on its journey;
(d) analyse plural routes or route portions from a plurality of sessions to identify statistically at least one pattern of road use by the vehicle category of interest; and
(e) generate said supplementary information based on the at least one pattern of road use by the vehicle category of interest.

Abstract
A technique is disclosed for enabling collection and/or refinement of digital map information for aiding navigation route planning for vehicles larger than ordinary cars, such as goods-vehicles, buses, and car+caravan combinations. In at least one embodiment, a profile of a vehicle'"'"'s characteristics, and one or more routes followed, are logged by a navigation device, and fed-back to a server that supports the navigation device with map data updates. At the server, or an alternative processing centre, the fed-back data from plural navigation devices is analysed to observe statistically the patterns of roads used by these vehicles, and to categorise these by the type of vehicle.
