    摘要: PROBLEM TO BE SOLVED: To provide a control device that can properly and at an early time, achieve a slip state of a second engagement device, when controlling the second engagement device to the slip state while a first engagement device is under a released state.SOLUTION: There is provided the control device 3 for controlling a drive device 1 wherein the first engagement device CS, a rotary electric machine 12, and the second engagement device C1 are provided in this order on a power transmission path connecting an input member I and an output member O. The control device includes: a loss torque estimation part 47 which derives an estimated loss torque which is an estimated value of a loss torque caused by the drag resistance of the first engagement device CS when the first engagement device CS is in a released state; and a specific slip time hydraulic control part 45b which, when the first engagement device CS is in a released state and a specific slip control is executed to make the second engagement device C1 in a slip state, sets a supply hydraulic pressure to the second engagement device C1 so that a transmission torque capacity of the second engagement device C1 becomes the capacity corresponding to an estimated input torque determined as a difference between the output torque of the rotary electric machine 12 and the estimated loss torque.
