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.
