Abstract

A power train for a motor vehicle is configured with a control unit operable to increase or decrease the flow of operating fluid as a function of the instantaneous demand for the supply of the operating fluid to at least one of multiple clutch arrangements in such a way that the control unit decreases or interrupts the flow of operating fluid when the supply demand is low and increases the flow of operating fluid unit when the supply demand is high.
