Abstract
A hybrid vehicle includes an engine, a first rotating electrical machine (first MG), a second rotating electrical machine (second MG), a planetary gear mechanism which mechanically couples these devices, a first inverter which drives the first MG, a second inverter which drives the second MG, and a controller. When the controller receives a fail signal from the first inverter, the controller performs shut-down control which brings the first inverter into a gate shut-down state with fuel supply to the engine being stopped. When the absolute value of an engine rotation speed Ne is more than or equal to a predetermined value α and the absolute value of a rotation speed Nm1 of the first MG is less than a threshold value β after the shut-down control is started, the controller determines that the first inverter has a short-circuit fault.
