Abstract: A control device for a dutch, which is provided between an operating machine and a drive shaft of an engine, controls the operation of a valve member for opening and closing an oil supply hole through which an oil reservoir chamber and a torque transmission chamber communicate. The control device refers to a target rotational speed of a rotational solid of the operating machine and to the acquired rotational speed of the rotational solid of the operating machine, calculates a proportional manipulated variable based on the deviation between the angular acceleration of the rotational solid and a target angular acceleration, and controls the operation of the valve member on the basis of this calculated proportional manipulated variable.

Abstract: A dual clutch-type transmission control device is provided which improves the accuracy with which transmission torque is learned. A dual-clutch transmission includes a clutch apparatus having a first clutch and a second clutch, a first input shaft, a second input shaft, a counter shaft, an output shaft, an auxiliary transmission portion including a first input gear pair and a second input gear pair, a main transmission portion including an output gear pair, and learning modules and the learning modules shift the main transmission portion into a neutral state, disengage both the first and second clutched generate a torque change in an engine by keeping the engine running at a predetermined revolution number, engaging partially one of the first and second clutches and thereafter engaging the other clutch gradually partially and learn an amount of change of torque associated with the torque change as transmission torque of the other clutch.
