Control device

摘要

A control device for a vehicle drive configured with a power transfer path that includes a first engagement device, a rotary electric machine, and a second engagement device. These elements being arranged in this order from an input member coupled to an engine to an output member that is coupled to the wheels of the vehicle. The control device is configured with an control section that controls output torque of the rotary electric machine such that a rotational speed becomes closer to a target rotational speed with both the first and second engagement devices brought into a slip engagement state and with the rotary electric machine generating electric power. The control section maintains control in which at least one of a temperature of the rotary electric machine and a temperature of an inverter is monitored as a monitoring target temperature.

1. A control device that controls a vehicle drive device in which a first engagement device, a rotary electric machine, and a second engagement device are provided on a power transfer path connecting between an input member drivably coupled to an internal combustion engine and an output member drivably coupled to wheels and are arranged in this order from a side of the input member, the control device comprising:
an electric power generation-rotational speed control section that executes electric power generation-rotational speed control in which output torque of the rotary electric machine is controlled such that a rotational speed of the rotary electric machine becomes closer to a target rotational speed with both the first engagement device and the second engagement device brought into a slip engagement state and with the rotary electric machine generating electric power, wherein during the electric power generation-rotational speed control, the electric power generation-rotational speed control section executes electric power generation amount maintaining control in which at least one of a temperature of the rotary electric machine and a temperature of an inverter is monitored as a monitoring target temperature, the target rotational speed is decided on the basis of the monitoring target temperature, and an amount of electric power generated by the rotary electric machine during the electric power generation-rotational speed control is maintained at a target electric power generation amount.
