Abstract: An actuating device for an automated dual clutch transmission of a motor vehicle drivetrain in manual-shift mode includes first and second shift elements disposed in a region of a steering column, the first shift element being configured to effect an upshift and the second shift element being configured to effect a downshift of the dual clutch transmission. Simultaneous operation of the shift elements is configured to effect idle operation of an engine with at least one open transmission clutch. The idle operation is present only while the first and second shift elements are actuated. The shift elements are configured to transmit a torque via a closed transmission clutch when at least one of the shift elements is released. A control device is configured to initiate rotational speed adaptation of the engine as a function of an actuation of the first and second shift elements.

Abstract: A method for shifting a semi-automatic powershift transmission used in a motor vehicle during a manually triggered traction upshift involves the shift phases of the charging of an actuator of a clutch to be engaged, an overlap of the charging of the actuator of the clutch to be engaged and the emptying of an actuator of a clutch to be disengaged, and also involves an engine rotational speed alignment. The charging, the overlap and the engine rotational speed alignment are carried out simultaneously. In the shift process during a manually triggered shift, the driver perceives a change in engine rotational speed with only a minimal delay after the shift command.
