Road information data is enriched and a vehicle drive train is controlled on basis of this data. Based on vehicle position, data about possible routes which may be taken is collected from at least three sources (A, B, C). Data with the highest quality is chosen for controlling the drive train. When running, information about the traveled route is recorded and saved, thus providing a continuous update. |

1. Method of enrichment of road information data, wherein the road information data is used to control a drive train of a vehicle, and wherein the drive train is controlled by an electronic control unit (ECU), the ECU having access to road information data from a plurality of different types of road information sources (A, B, C), and a position sensor (P), wherein the road information sources (A, B, C) at least comprises; a digital map (A), a fleet database (B) and a local vehicle database (C), and wherein the ECU is adapted to make a selection between road information data from the plurality of road information sources (A, B, C), wherein the selection is based on a data quality rating of the road information data from the different road information sources (A, B, C), and the method comprising
determining a position of the vehicle, collecting road information data, about possible routes in surroundings of the position of vehicle, from the plurality of road information sources (A, B, C), evaluating the data quality rating of the collected road information data, selecting the road information data with the highest data quality rating, and controlling at least one vehicle parameter, dependent of the selected road information data, recording road information data about a traveled route as the vehicle is moving, and during, move of the vehicle, performing the steps of; making a selection of relevant recorded road information data, and saving the relevant, road information data to the local database (C). |
