Abstract:
1. A method for controlling a driving distance between a host vehicle and as first vehicle driving in front of the host vehicle, the host vehicle driving at a driving speed and at the driving distance to the first vehicle, the host vehicle comprising: a system for controlling the driving distance, which is adapted to retain the driving distance at not less than a minimum safety distance: and a fuel saving system, which includes an automatic speed increasing function, which automatic speed increasing function, upon fulfilment of a set of conditions, is activated to automatically increase the driving speed in order to utilise the kinetic energy inherent in the host vehicle to save fuel, the method comprising the steps of: retrieving information to prepare for activation of the automatic speed increasing function; preparing for the activation by wherein the host vehicle comprises freewheeling means, by means of which a propulsion unit is disconnectable from driving wheels of the host vehicle, and wherein the step of activating the automatic speed increasing function includes launching of the freewheeling means.
