An engine and a step up-down converter are controlled such that a counter-electromotive voltage of a first motor becomes higher than direct current-side voltages of a first inverter and a second inverter and thereby torque for forward travel is output from the first motor to a driving shaft through a planetary gear set, when an accelerator is on during specified travelling with gates of the first inverter and the second inverter being cut off and the engine being operated. The engine and the step up-down converter are controlled such that the rotational speed of the first motor becomes smaller and the voltage of the high voltage-side electric power line becomes lower when the accelerator is off than when the accelerator is on during the specified traveling.
