An electrical differential section that functions as an electrical differential device having a differential mechanism that distributes engine output to the first motor and the transmission member, and a second motor that is capable of transmitting power to the drive wheels ; A control device for a vehicle drive device comprising an automatic transmission portion that constitutes a part of the power transmission path and functions as an automatic transmission,
An engagement device that selectively switches the power transmission path between a power transmission enable state and a power transmission cutoff state;
Shift that is manually switched between a drive position for selecting switching to the power transmission enabled state by the engagement device and a non-drive position for selecting switching to the power transmission cut-off state by the engagement device An operating device;
When the shift operation device is switched from the non-driving position to the driving position, the engagement device is engaged to make the power transmission path in a state where power can be transmitted, and the first device is engaged after the engagement device is engaged. Output control means for controlling the rising of the output torque from the electrical differential unit using the electric motor and / or the second electric motor. 2. The control device for a vehicle drive device according to claim 1, wherein the output control means controls the engagement device to be rapidly engaged when the engagement device is engaged. The output control means uses the first electric motor and / or the second electric motor to suppress the relative rotational speed of the engagement device so that the rotational speed of the transmission member becomes a rotational speed corresponding to the vehicle speed. The control device for a vehicle drive device according to claim 1 or 2, wherein the control device controls rotation speed. 4. The control device for a vehicle drive device according to claim 3, wherein the output control means executes rotation speed control of the rotation speed of the transmission member before the engagement of the engagement device is started. The control device for a vehicle drive device according to claim 3 or 4, wherein the output control means executes a rotational speed control of a rotational speed of the transmission member when the engine is operated. The output control means changes a rising characteristic of output torque from the electrical differential unit based on whether the drive position is a forward drive position or a reverse drive position. control device according to any one of the vehicle drive device of claims 1 to 5 is. The control device for a vehicle drive device according to any one of claims 1 to 6, wherein the output control means changes a rising characteristic of an output torque from the electrical differential unit based on a required output value. The automatic transmission unit is a stepped automatic transmission, and the engagement device is a friction engagement device used to establish a shift stage of the stepped automatic transmission,
When the shift operation device is switched to the non-driving position, the stepped automatic transmission is in a power transmission cut-off state by the engagement device, and the shift operation device is switched to the drive position. The vehicle drive device control device according to any one of claims 1 to 7, wherein the stepped automatic transmission is enabled to transmit power by the engagement device.
