METHOD FOR REGULATING THE DISTANCE OF A VEHICLE FROM A PRECEDING VEHICLE
First Claim
1. A method for regulating a distance of a first vehicle from a preceding vehicle, based on a vehicle speed of the first vehicle, the distance, a speed of the preceding vehicle, and data about road route information, the method comprising:
- determining a fuel-saving situation form fuel-saving momentum utilization phase in the route ahead,precomputing a consumption optimal speed profile with an associated speed variation and an associated momentum utilization phase distance for undisturbed travel,precomputing an additional separation requirement to the preceding vehicle ahead based on the speed variation and the momentum utilization phase distance required to fully implement the precomputed fuel-saving momentum utilization phase without a defined, excessively close approach to the preceding vehicle,building up the required additional separation prior to the fuel-saving situation, wherein the additional separation is built up over a separation build-up distance that is longer than the precomputed momentum utilization phase distance and/or with a driver-acceptable, convoy-stabilizing, defined small speed reduction relative to the current vehicle speed,carrying out the fuel-saving momentum utilization phase on reaching the fuel-saving situation.

Abstract
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 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.
