Abstract: The hybrid vehicle performs battery-less drive control to control an engine such that the engine is autonomously operated at an autonomous operation rotation speed, to control a first motor such that a torque based on a driving force required for a run of the hybrid vehicle is output from the first motor, and to control a second motor such that an electric power by subtracting an auxiliary machinery power from an electric power charged or discharged by the first motor is charged or discharged by the second motor. During the battery-less drive control, when a rotation speed of the engine becomes lower than a first predetermined rotation speed that is lower than the autonomous operation rotation speed, the hybrid vehicle performs torque adjustment control to decrease an absolute value of the torque output from the first motor.

Abstract: A hybrid vehicle in which a first inverter is turned on in three phases and injection of fuel of an engine is stopped when an accelerator is turned off during predetermined traveling in which the hybrid vehicle is traveling with gates of the first inverter and the second inverter cut off and with the engine operating is provided. Accordingly, when an accelerator is turned off during the predetermined traveling, it is possible to rapidly decrease a drag torque of a first motor.
