Abstract
A system for controlling or regulating the longitudinal speed of a motor vehicle includes an operating element for defining a desired longitudinal acceleration value as a function of a pertaining operating element actuating quantity. In a first embodiment of the invention, the system sets the longitudinal speed of the vehicle to the desired value adjusted by way of the operating element if the amount of this value is above a definable threshold value. Otherwise it sets a constant longitudinal speed which is lower than the actual vehicle speed at the moment when the set desired longitudinal acceleration value falls below the threshold value, by a differential value defined as a function of the speed. In a second embodiment which is preferably combined with the first embodiment, the adjusting sensitivity of the desired longitudinal acceleration value decreases with increasing longitudinal speed.
