Provided are methods and control units for building a database and for predicting a route of a vehicle, and estimating length of the predicted route. The method comprises determining geographical position of the vehicle; detecting a cell border of a cell in a grid-based representation of a landscape, in a database, corresponding to the geographical position; determining that the vehicle is entering the cell at the cell border; extracting a stored driving direction at the cell border from the database; detecting a cell border of a neighbor cell, in the driving direction at the cell border; repeating step and; predicting the route of the vehicle; and estimating the length of the predicted route by adding an estimated distance through each cell of the predicted route.

Methods and control units for building a database and for predicting a route of a vehicle

A method and control unit determines a fuel efficient acceleration behavior of a motor vehicle for a predetermined road section. The determination of the acceleration behavior is based on a determined initial speed of the motor vehicle in a first position in the road section, and a determined target speed of the motor vehicle in a determined second position in the road section, the second position being separated from the first position by an acceleration distance. The first position is determined such that the acceleration distance is less than or equal to a maximal acceleration distance S, the maximal acceleration distance Sbeing dynamically determined based on at least one first road condition for the road section and on at least one characteristic of the motor vehicle.
