Abstract:
A cruise control method for controlling an actual speed of a motor vehicle to a set speed, a speed regulation interval being a range of actual speeds including the set speed during which the actual speed is controlled by speed regulation, the actual speed being controlled by acceleration regulation so long as the actual speed is outside the speed regulation interval, the method comprising the steps of:(1) when the actual speed (v.sub.act) transitions into the speed regulation interval such that control of the actual speed changes from acceleration regulation to speed regulation;determining an actual value of a roadway gradient characteristic (a.sub.diff); and(2) selecting a speed control parameter set as a function of the roadway gradient characteristic actual value, the speed control parameter set being selected from a plurality of speed control parameter sets which are predetermined differently for different possible roadway gradient characteristic values and are specific for the roadway gradient.
