摘要： An apparatus for changing the transmission ratio of a continuously adjustable transmission as part of a cruise control system for motor vehicles, this part being provided with a controller (18) for the formation of a change value (ISOLL) for the transmission ratio as a function of the difference by which the actual value of the speed of travel (VIST) in overrun operation exceeds a stipulated value (VSCHRUB). An adding stage (20) is used for the formation of a desired value (ISOLL—F) for the transmission ratio from the change value (ISOLL) and the stored desired value (IVSCHUB) of the transmission ratio at the beginning of overrun operation, it being possible for this desired value (ISOLL—F) to be fed to a transmission-ratio controller for the transmission. As a result, a defined increase in vehicle speed leads to a similar change in the transmission ratio in each vehicle-speed range, and the transmission intervention is always ended exactly at the same transmission ratio at which it began. Moreover, decelerations by means of the cruise-controller operating lever are always reproducible down to a constant minimum value, irrespective of the particular vehicle-speed or engine-speed range.
