Abstract: In a vehicle drive device including a transmission mechanism 54, a range changing mechanism 55, a motor generator MG1 or MG2, and a control device 200, 300, when a clutch sleeve 553 becomes unable to slide during a range changing process, the clutch sleeve 553 is restored as quickly as possible so that the clutch sleeve 553 can slide, whereby changing of ranges can be completed. The control device 200, 300 causes a connection target gear piece 551 or 552 to rotate in the same direction as the direction of input rotation to the transmission mechanism 54 in response to a range change request, and causes the clutch sleeve 553 to slide. When determining that the clutch sleeve 553 has become unable to slide during the range change process, the control device 200, 300 causes the motor generator MG1 or MG2 to rotate the connection target gear piece 551 or 552 in a direction opposite to the direction of input rotation to the transmission mechanism 54.
