CRUISE CONTROL FOR A MOTOR VEHICLE AND CONTROL METHOD

摘要

The present invention relates to a cruise control for a motor vehicle (1) provided with a power train which is adapted to assuming various transmission ratios for propulsion of the vehicle (1) and which comprises at least one engine (10) and at least one gearbox (20), such that the cruise control (40) is adapted to being controlled on the basis of a first parameter Rp which is defined as a difference between a first motive force F Max and a second motive force For, the first motive force F Max being a maximum motive force available for the vehicle (1) at a current power train transmission ratio and the second motive force For a current running resistance for the vehicle (1). The invention relates also to a computer programme and a computer programme product, and to a motor vehicle provided with such a cruise control.
