Patent abstract

A hydraulic system in motor vehicles with at least one hydraulically actuated clutch, which entails minimized control complexity for supplying the clutch with hydraulic oil and which takes up less structural space. These characteristics are achieved essentially in that the pressure control of the hydraulically actuated clutch is effected directly and exclusively by an electrically driven and electronically controlled oil pump.
