Abstract:
1. A control arrangement for an automated gear shift transmission for a motor vehicle, with a first partial transmission ( 26 ), having a main shaft ( 14 ) and a countershaft ( 16 ) with different gear sets including idler gears and fixed gears, which can be engaged by coupling respectively one idler wheel ( 17 a , 17 b , 17 c , 17 d ) with the countershaft ( 16 ), and a gear actuation system ( 62 ), which has a first fluid-actuated shift device ( a first gear slide (SS GS a supply pressure slide (RS GS), by means of which a supply pressure can be directed to the gear slide (SS GS the first gear slide (SS GS a connection of the supply inputs ( the supply pressure slide (RS GS) having a first and a second supply output ( the supply pressure slide (RS GS) being designed in such a manner that it can guide a supply pressure optionally to one of the two supply outputs ( the gear actuation system ( 62 ) having a second shift device ( 19 ) of the first partial transmission ( 26 ) and an associated second gear slide (SS GS 51 ) and the second gear slide (SS GS 51 ) having two supply inputs ( 67 , 68 ), which are connected to the supply outputs ( 71 , 72 ) of the supply slide (RS GS) and a blocking device ( 120 , 121 ) for preventing a simultaneous selection of two shift devices ( 18 , 19 ) of the first partial transmission ( 26 ).
