Provided is technology whereby the touch points at which a clutch (20) starts to engage can be detected, in a hybrid drive device having: the clutch (20) which connects and disconnects an output shaft (EG-1) of an engine and an input shaft (51) of a gear mechanism; and a motor generator (MG1) that rotates in conjunction with the rotation of the input shaft (51). A rotation speed sensor (MG1-1) detects changes in the rotation speed of a first motor generator (MG1); a first inverter (31) detects changes in the torque of the first motor generator (MG1); and a control unit (40) detects, as a touch point, the status of the clutch (20) when a change in rotation speed or torque is detected for the first motor generator (MG1), when the clutch (20) in the disengaged state is engaged.
