    摘要： A torque transfer mechanism having a multi-plate friction clutch connecting a pair of rotary members and an electrohydraulic clutch actuator for controlling engagement of the friction clutch. The clutch actuator includes a hydraulic pump, a hydraulically-actuated rotary operator, and a ball ramp mechanism. The hydraulic pump draws low pressure fluid from a sump and delivers high pressure fluid to a series of actuation chambers defined between coaxially aligned first and second components of the rotary operator. The magnitude of the fluid pressure delivered to the actuation chamber controls angular movement of the second component relative to the first component for energizing the ball ramp mechanism. The ball ramp mechanism applies a clutch engagement force on the friction clutch assembly, thereby transferring drive torque from the first rotary member to the second rotary member. A hydraulic control system adaptively regulates the fluid pressure delivered to the actuation chamber.

    摘要： An embodiment of a control method for carrying out a gear shifting in an automatic manual transmission having a dual-clutch gearbox to pass from a current shorter gear to a successive longer gear; the embodiment includes the steps of: receiving a gear shifting command; opening a first clutch associated to the current gear; closing a second clutch associated to the successive gear in a same first moment; finishing the opening of the first clutch associated to the current gear and finishing the closure of the second clutch associated to the successive gear in a same closing moment; keeping the rotation speed of the drive shaft of the engine constant and equal to an initial value imposed by the gear ratio of the current gear until the closing moment in which the opening of the first clutch is completed; after the closing moment, progressively decreasing the rotation speed of the drive shaft of the engine from the initial value imposed by the gear ratio of the current gear to a final value imposed by the gear ratio of the successive gear; and temporarily overlengthening the second clutch after the closing moment so that the second clutch temporarily transmits an additional torque which determines a progressive reduction of the rotation speed of the drive shaft from the initial value to the final value.
