METHOD AND COMPUTER PROGRAM PRODUCT FOR ESTIMATING A TRAVEL TIME FOR A VEHICLE
First Claim
1. A method for estimating a travel time for a vehicle (10) comprising the steps of:
- determining a route for which the travel time is to be estimated;
dividing said route into route sections (32, 34, 36), wherein each route section has substantially constant road characteristics;
selecting a vehicle configuration for said vehicle (10);
retrieving, from a database, an estimated travel time for each route section based on each route section for said selected vehicle configuration; and
aggregating the estimated travel times for each route section from the database into a total travel time for said determined route.

16. A method for creating a database for use of estimating a travel time for vehicles (10, 14), comprising:
-
defining a plurality of vehicles (10, 14), each vehicle with a plurality of configurations, for which the travel time is to be estimated; defining a plurality of route sections (32, 34, 36), wherein each route section has substantially constant road characteristics; and generating a database comprising traveling data corresponding said defined vehicles traveling along said route sections, wherein said traveling data comprise vehicle speed curves representing; said vehicles accelerating to a predetermined cruising speed (VC); said vehicle traveling in a predetermined cruising speed (VC); said vehicle decelerating to a predetermined cruising speed (VC); and
/orbraking said vehicle to substantially standing still.
