Abstract

A method for controlling an electro-hydraulically operated infinitely variable transmission of a motor vehicle which is driven, in particular, by an internal-combustion engine, provides a control of the infinitely variable transmission according to several characteristic control curves. The characteristic control curves are selected corresponding to a driving activity which evaluates the driver's driving style or his action with respect to the control of the motor vehicle caused by a traffic situation. The characteristic control curves cover, at least in steps, the range between a characteristic control curve permitting the consumption-optimized operation of the motor vehicle and a characteristic control curve which permits the power-optimizing operation of the motor vehicle.
