Determination of acceleration behaviour
First Claim
1. A method for determining, setting, and controlling a fuel efficient acceleration behavior of a motor vehicle for a predetermined road section comprising:
- determining an initial speed of said motor vehicle in a first position in said road section, anddetermining a target speed of said motor vehicle in a determined second position in said road section, wherein said second position is separated from said first position by an acceleration distance;
dynamically determining a maximal acceleration distance Sacc based on at least one first road condition for said road section and on at least one characteristic of said motor vehicle and said first position is determined such that said acceleration distance is shorter than or equal to said maximal acceleration distance Sacc;
setting said initial and target speeds of said motor vehicle and said acceleration distance of said motor vehicle based on said determined initial and target speeds and acceleration distance; and
controlling a speed of said motor vehicle, by a speed altering device of said motor vehicle, so that said motor vehicle reaches said set initial speed at said first position in said road section and reaches said set target speed at said second position in said road section, whereby said motor vehicle travels said set acceleration distance between said first position and said second position.

Abstract
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 Sacc, the maximal acceleration distance Sacc being dynamically determined based on at least one first road condition for the road section and on at least one characteristic of the motor vehicle.
