Abstract:
1. A control device for a vehicle drive device including an input member drivably coupled to an internal combustion engine, an intermediate member drivably coupled to a rotary electric machine, an output member drivably coupled to wheels, a first engagement device that selectively drivably couples the input member and the intermediate member to each other, and a second engagement device that selectively drivably couples the intermediate member and the output member to each other, wherein a difference in rotational speed between engagement members on both sides of the first engagement device is defined as a first differential rotational speed, and a difference in rotational speed between engagement members on both sides of the second engagement device is defined as a second differential rotational speed, the control device comprising: an electronic control unit that is programmed to perform a specific starting control when a vehicle is started with the rotary electric machine continuously generating electric power from a state in which the rotary electric machine generates electric power with the first engagement device providing no first differential rotational speed and in which the second engagement device transfers no drive force is executed, wherein the specific starting control includes a differential rotational speed control region in which the first engagement device is transitioned from a state in which the first engagement device transfers a drive force while providing no first differential rotational speed to a state in which the first engagement device transfers a drive force while providing the first differential rotational speed, and in which the second engagement device is transitioned from a state in which the second engagement device transfers no drive force to a state in which the second engagement device transfers a drive force while providing the second differential rotational speed.
