A control device for a vehicle drive device includes performing neutral travel control in which disengagement/engagement elements are disengaged with the wheels rotating so the state of a speed change mechanism is controlled into a neutral state where transfer of a drive force between the input member to the engine and the output member to the wheels is not performed, and the wheels are driven by a rotary electric machine drive force; and comparing an operating state value of each of target actuators that control the state of the disengagement/engagement elements, and a determination value so torque from the speed change mechanism to the wheels because of torque transferred by each of the disengagement/engagement elements, falls within an allowable range during neutral travel control, and determines whether the torque transferred from the speed change mechanism to the wheels falls within the allowable range.

Control device for vehicle drive device

A control device for a vehicle. While subject control is performed, a second engagement control unit controls the engagement pressure of the second engagement device to a mid-control set pressure that has been set to be equal to or more than a first engagement pressure and equal to or less than a second engagement pressure. The first engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which requested torque that is torque required to be transmitted to the wheels is transmitted to the wheels. The second engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which maximum output torque of the rotary electric machine is transmitted to the wheels.
