A method for regulating a distance of a vehicle from a preceding vehicle (vehicle ahead) based on available information for the subject vehicle's speed, for the distance and for the speed of the vehicle ahead and on data regarding route information includes determining a fuel-saving situation for a fuel saving momentum utilization phase, and precomputing a consumption optimal speed profile for undisturbed travel. The method further precomputes an additional separation requirement to the vehicle ahead that is required to be able to fully implement the momentum utilization phase, and builds up the required additional separation prior to the fuel-saving situation, wherein the additional separation is built up, preferably substantially uniformly, over a separation build-up distance that is longer than the precomputed momentum utilization phase distance and/or is built up with a driver-acceptable, convoy-stabilizing, defined small speed reduction relative to the current speed of the vehicle. The momentum utilization phase on reaching the fuel-saving situation.
