Hybrid vehicle

A hybrid vehicle comprising:

• an internal combustion engine;
• a first rotary electric machine;
• a second rotary electric machine configured to output power to a drive wheel;
• a power transmission unit including an input element, an output element and an engaging portion, the input element being configured to receive power from the internal combustion engine, the output element being configured to output power input to the input element, and the engaging portion being configured to switch between a non-neutral state where power is transmitted between the input element and the output element and a neutral state where power is not transmitted between the input element and the output element;
• a differential unit including a first rotating element, a second rotating element and a third rotating element, the first rotating element being connected to the first rotary electric machine, the second rotating element being connected to the second rotary electric machine and the drive wheel, the third rotating element being connected to the output element, and the differential unit being configured such that, when rotation speeds of any two of the first rotating element, the second rotating element and the third rotating element are determined, a rotation speed of the remaining one of the first rotating element, the second rotating element and the third rotating element is determined;
• a clutch configured to switch between an engaged state where power is transmitted from the internal combustion engine to the first rotary electric machine and a released state where transmission of power from the internal combustion engine to the first rotary electric machine is interrupted, power from the internal combustion engine being transmitted to the first rotary electric machine through at least one of a first path or a second path,
• the first path being a path through which power is transmitted from the internal combustion engine to the first rotary electric machine via the power transmission unit and the differential unit,
• the second path being a path through which power is transmitted from the internal combustion engine to the first rotary electric machine, being different from the first path, not including the differential unit, and the clutch being provided in the second path;
• and
• a mechanical oil pump configured to generate hydraulic pressure for activating the power transmission unit and the clutch, the mechanical oil pump being configured to be driven by power that is transmitted from any one of the first rotating element, second rotating element and third rotating element of the differential unit.
