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. A mode control unit switches among a first, second, third and fourth control modes in which the rotating electrical machine generates electricity with: (i) both the first and second engagement devices, (ii) both the first and second engagement devices, (iii) the first engagement device in the direct engagement state and with the second engagement device, and (iv) with the first engagement device in the slip engagement state and with the second engagement device.

1. A control device that controls a vehicle drive device in which a first engagement device, a rotating electrical machine, and a second engagement device are sequentially provided from an internal combustion engine side in a power transmission path connecting an internal combustion engine and wheels, comprising:
a mode control unit that switches among a first control mode in which the rotating electrical machine is caused to generate electricity with both the first engagement device and the second engagement device in a slip engagement state, a second control mode in which the rotating electrical machine is caused to generate electricity with both the first engagement device and the second engagement device in a direct engagement state, a third control mode in which the rotating electrical machine is caused to generate electricity with the first engagement device in the direct engagement state and with the second engagement device in the slip engagement state, and a fourth control mode in which the rotating electrical machine is caused to generate electricity with the first engagement device in the slip engagement state and with the second engagement device in the direct engagement state; and a target-amount obtaining unit that obtains at least one of a temperature and a heat generation amount of the second engagement device as a selection target amount, wherein in at least one of a mode shift from the first control mode to the second control mode and a mode shift from the second control mode to the first control mode, the mode control unit executes the mode shift directly via only the third control mode if the selection target amount is smaller than a predetermined selection reference value, and executes the mode shift directly via only the fourth control mode if the selection target amount is equal to or larger than the selection reference value.
