Hybrid vehicle

A hybrid vehicle comprising:

• an engine;
• a first motor;
• a second motor;
• a gear transmission mechanism configured to transmit torque, output from the first motor, to a drive shaft side;
• an oil supply mechanism configured to be driven by power other than power of the engine, the oil supply mechanism being configured to supply oil to the gear transmission mechanism;
• and
• an electronic control unit,
• wherein the gear transmission mechanism is a planetary gear mechanism including, as rotating elements, a sun gear, a ring gear and a carrier to which torque output from the engine is transmitted, the first motor is coupled to one of the sun gear and the ring gear, an output member that transmits power to the drive shaft side is coupled to the other one of the sun gear and the ring gear, the second motor is coupled to the output member, a brake mechanism that selectively stops rotation of the carrier is coupled to the carrier, and
• when the hybrid vehicle travels by using torque output from both the first motor and the second motor in a state where operation of the engine is stopped and rotation of the carrier is stopped by the brake mechanism, the electronic control unit is configured to (i) estimate an amount of the oil that is supplied from the oil supply mechanism to the planetary gear mechanism and (ii) when the estimated amount of the oil supplied is smaller than or equal to a predetermined amount, limit an operation state of the first motor such that load on the planetary gear mechanism decreases.
