Abstract
There is provided a hybrid vehicle comprising an engine; a first motor configured to generate a reverse voltage by rotation; a planetary gear mechanism configured such that three rotational elements are respectively connected with a driveshaft coupled with an axle, with the engine, and with the first motor; a second motor configured to input and output power from and to the driveshaft; a first inverter configured to drive the first motor; a second inverter configured to drive the second motor; a power storage device; and a converter placed between the power storage device and the first inverter along with the second inverter. In an evacuation travel with an accelerator-on operation during an inverter failure, the hybrid vehicle shuts off gates of the first inverter and the second inverter, controls a rotation speed of the engine such as to rotate the first motor at a predetermined rotation speed, and controls a voltage of a second power line such as to maximize an inter-line current that flows from the second power line to a first power line via the converter.
