Abstract
A hydraulic control unit is set up to hydraulically actuate a starting clutch of a motor vehicle and gear selectors of a transmission of the motor vehicle by use of hydraulic valves which are integrated in the hydraulic control unit and which have in each case at least one control element. The hydraulic control unit is characterized in that the integrated hydraulic valves are aligned in the hydraulic control unit in such a way that a movement direction of a vibratory element of a hydraulic valve which controls only the starting clutch differs from the movement direction of vibratory elements of the other hydraulic valves, and is aligned to a lesser extent with the longitudinal axis of the motor vehicle.
