Claim Text:
1. A failure diagnosis apparatus of a hybrid vehicle including an internal combustion engine, a rotary electric machine that generates electric power by using power of the internal combustion engine, an electric power storage device, and an electric power supply device that supplies the electric power generated by the rotary electric machine and electric power stored in the electric power storage device to power receiving equipment outside the vehicle, the failure diagnosis apparatus comprising: a controller that is configured to execute a first failure diagnosis process of the internal combustion engine based on a first diagnosis requirement in a case where engine-operation-electric-power supply is executed in which the internal combustion engine is operated to cause the rotary electric machine to generate electric power and the generated electric power is supplied to the power receiving equipment via the electric power supply device, the controller being configured to execute a second failure diagnosis process of the internal combustion engine based on a second diagnosis requirement in a case where engine-normal-operation is executed in which the internal combustion engine is operated and the rotary electric machine does not generate the electric power to be supplied to the power receiving equipment, wherein a failure of the internal combustion engine in the first failure diagnosis process of the internal combustion engine is less likely to be detected or the failure of the internal combustion engine in the first failure diagnosis process of the internal combustion engine is less likely to be recognized by a driver than the failure of the internal combustion engine in the second failure diagnosis process of the internal combustion engine.
