Patent ID: 8033106

Claim:
An electrohydraulic transmission controller ( 7 ) comprising several electrically actuatable pressure control valves ( 9 to 16 ), a plurality of valve arrangements ( 17 to 34 ), each of which are controlled by a hydraulic pre-control pressure depending the activation of the pressure control valves ( 9 to 16 ), a plurality of switching elements (A, B, C, D, E) of a transmission device ( 3 ) are actuated by a control pressure for engaging an operating state of the transmission device ( 3 ), an additional pressure control valve ( 9 ) adjusts another pre-control pressure (p_VS_ 9 ) of an additional valve arrangement ( 35 ) such that, downstream of the additional valve arrangement ( 35 ), a sub-assembly ( 6 ) of a motor vehicle drive train ( 1 ) is acted on by a cooling oil volume flow that is subject to the other pre-control pressure (p_VS_ 9 ) of the additional valve arrangement ( 35 ) and an operating state of the additional valve arrangement ( 35 ) corresponding to it.
