Abstract
A clutch control system for a twin-clutch type automatic/manual transmission AMT includes a hydraulic pump for driving a first clutch and a second clutch and oil passages for transmitting oil pressures and an AMT control unit for controlling the supply of oil pressures into the oil passages. Upon detection of an engine starting operation, the AMT control unit performs an initial preparatory operation in which the oil pressures are supplied into the oil passages at different timings so as to fill up the oil passages with a working oil, thereby completing the preparations for driving of the clutches. When the oil pressure is supplied into the oil passage after a predetermined oil pressure is generated in the oil passage, the period of time taken for a first speed gear to become usable is shortened, whereby a swift vehicle starting after the starting of the engine can be achieved.
