1. An oil supply device that supplies oil to a vehicle drive device that includes an input member drivably coupled to an internal combustion engine, a rotary electric machine for driving wheels, an output member drivably coupled to the wheels, a speed change device that includes a shifting engagement device and that at least transfers rotation of the input member to the output member with the speed of the rotation changed, and a decoupling engagement device that decouples the input member from the speed change device, comprising:
a first hydraulic pump driven by one of a first interlocking member, which operates in conjunction with the input member, and a second interlocking member, which operates in conjunction with the rotary electric machine, that is rotating at a higher rotational speed; a second hydraulic pump driven by a drive force source that is different from a drive force source for the first hydraulic pump; a lubrication oil passage that supplies oil for lubrication to at least one of the decoupling engagement device and the shifting engagement device; a first engagement oil passage that supplies oil for controlling a state of engagement to the decoupling engagement device; a second engagement oil passage that supplies oil for controlling a state of engagement to the shifting engagement device; and a supply state control section that controls a state of supply of oil discharged from each of the first hydraulic pump and the second hydraulic pump to each of the oil passages, wherein: a state in which oil discharged from the first hydraulic pump is supplied to both the first engagement oil passage and the second engagement oil passage and in which at least oil discharged from the second hydraulic pump is supplied to the lubrication oil passage is defined as a first supply state; a state in which oil discharged from the first hydraulic pump is supplied to the second engagement oil passage and in which no oil is supplied to the first engagement oil passage or a state in which oil is supplied to neither the first engagement oil passage nor the second engagement oil passage is defined as a second supply state; and the supply state control section establishes the first supply state in the case where rotation of the input member is transferred to the output member with at least one of the decoupling engagement device and the shifting engagement device controlled to a slipping engagement state, and establishes the second supply state in the case where output torque of the rotary electric machine is transferred to the wheels with the decoupling engagement device controlled to a disengaged state. |
