Abstract
An apparatus for adjusting the output torque, or the output power, of a continuously variable transmission in vehicles propelled by combustion engines to a predetermined value, has a calculating unit (15) for setting a target value for the output torque or power M ab Soll as a function of an accelerator position (14;2) and vehicle speed (nab). An engine torque target value is calculated (units 18, 19, 20) as a function of the so value and an actual or instantaneous transmission ratio value or speed (u n ist). Target values of a transmission ratio are calculated in a unit (16), including a look-up table or an algorithm for storing or calculating transmission ratio values as a function of transmission output speed and of the accelerator pedal position (14;2) or the transmission output torque target value in accordance with a predeterminable engine operating strategy (e.g. optimum fuel efficiency, or performance, or driving comfort.
