Hydraulic control device of dual clutch transmission

The invention relates to a control device (1) of a dual clutch transmission. The device is provided with at least a pressure adjusting valve (3), a plurality of gears adjusting valves (4), and two clutch adjusting valves (6,7). The gears adjusting valves (4) can be supplied by at least a pressure adjusting valve (3). When at least a pressure adjusting valve (3) is out of order, the gears adjusting valves (4) and at least a clutch adjusting valves (6,7) can be supplied. When at least a pressure adjusting valve (3) is out of order, an emergency driving function can be realized through low cost and simple methods. The device is provided with two safety valves (S1, S2) distributed to the clutch adjusting valves (6,7), wherein at least a safety valve (S1) is effectively connected with the gears adjusting valves (4) on functions through a bridging pipe (8). On the bridging valve position of the safety valve (S1), the pressure adjusting valve (3) can be bridged through the bridging pipe (8).
