·
OSTI ID:6954156
This patent described a clutch control system for regulating torque transfer from an engine through a continuously variable transmission to an associated driveline mounted in a vehicle. A fluid-actuated clutch is operable to transfer drive torque to the associated driveline. A clutch supply line is connected to supply fluid to apply the clutch and to discharge fluid to release the clutch, and a clutch control valve assembly is coupled to the clutch supply line. The clutch control system comprises: a mode determination circuit connected to supply mode output signals to place the clutch control system in one of a plurality of operating modes, including start mode and drive mode; means for supplying a plurality of information input signals, including a vehicle speed signal and a clutch input speed signal, to the mode determination circuit, and means, in the clutch control system, for providing a regulating signal for the clutch control valve assembly which varies in accordance with the operating mode selected by the mode determination circuit.
