Patent ID: 8498765

Claim:
A control device designed to control a vehicular drive device that has a rotating electrical machine provided in a drive train path connecting an input member drivingly coupled to an internal combustion engine with an output member drivingly coupled to wheels, has a first engagement device provided between the input member and the rotating electrical machine, and has a second engagement device provided between the rotating electrical machine and the output member, the control device being structured to be able to perform specific electric power generation control that causes the rotating electrical machine to carry out electric power generation when both the first engagement device and the second engagement device are in a slip engagement state, and the control device comprising: a controller configured with a processor and internal storage, the controller capable of executing various functions to control aspects of the vehicular device, the controller programmed with functional portions comprising: a first engagement device operation control portion controlling an engagement pressure of the first engagement device making a rotational speed of the input member equal to a predetermined rotational speed during the specific electric power generation control; a second engagement device operation control portion controlling an engagement pressure of the second engagement device making a transfer torque capacity of the second engagement device equal to a predetermined transfer torque capacity during the specific electric power generation control; and a rotating electrical machine control portion determining a target rotational speed maintaining a state in which an electric power generation amount achieved by the rotating electrical machine coincides with a predetermined target electric power generation amount, in accordance with a magnitude of a differential torque as a difference between a torque transmitted via the first engagement device and a torque transmitted via the second engagement device, in performing rotational speed control for causing a rotational speed of the rotating electrical machine to follow the target rotational speed by issuing a command of the target rotational speed to the rotating electrical machine during the specific electric power generation control.
