Abstract:
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 for a 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 required to implement the fuel-saving momentum utilization phase, precomputing, based on the speed variation and the momentum utilization phase distance, an additional separation requirement to the preceding vehicle ahead that is required upon reaching the fuel-saving situation 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, after building up the required additional separation, the fuel-saving momentum utilization phase on reaching the fuel-saving situation.
