To provide a control unit of a hybrid drive device for preventing or suppressing deterioration in regenerating efficiency and for avoiding or suppressing occurrence of the excess and shortage of transfer torque of a speed change mechanism in decelerating and breaking a vehicle.
A control unit of a hybrid drive device comprising an internal combustion engine; a speed change mechanism capable of changing a transfer torque capacity; a transfer mechanism having a friction engagement device; and a motor generator, includes a friction engagement device control means for releasing the engagement device in executing regenerating control (Steps S1, S2); a dragging torque calculation means for obtaining dragging torque of the friction engagement device (Step S3); a transmission transfer torque calculation means for calculating transfer torque at the speed change mechanism from the dragging torque of the friction engagement device (Step S5); and a transfer torque capacity control means for controlling a transfer torque capacity of the speed change mechanism on the basis of the transfer torque (Step S6).
