Abstract: An electronic control unit of a hybrid vehicle controls an engine and an inverter to execute inverterless traveling. The inverterless traveling is a traveling state where the inverter is set to a gate blocking state, and where a reaction force of a torque that is output by a rotating electric device when the rotating electric device to be rotated by output of the engine generates electric power is applied to an output shaft. The electronic control unit controls a converter to adjust a voltage of an electric power line to a predetermined maximum voltage or a voltage within a predetermined range from the maximum voltage when a shift range of the hybrid vehicle is switched to a non-forward range from a forward range during the inverterless traveling.

Abstract: During a predetermined drive in which a hybrid vehicle is driven with shutting off gates of a first inverter and a second inverter and operating an engine, the hybrid vehicle controls the engine and a step-up/down converter, such that a reverse voltage of a first motor is higher than a voltage of a high voltage-side power line. In the event of an increase in an operation amount of an accelerator during the predetermined drive, the hybrid vehicle controls the engine and the step-up/down converter to limit an increment of a difference between the reverse voltage of the first motor and the voltage of the high voltage-side power line when a temperature of the step-up/down converter is equal to or higher than a predetermined temperature, compared with an increment of the difference when the temperature of the step-up/down converter is lower than the predetermined temperature.

Abstract: A vehicle includes an engine, an MG (motor generator) an MG2, a planetary gear device mechanically coupled to the engine and MG1 and MG2, a battery, an inverter configured to perform a power conversion between the battery and MG1 and between the battery and MG2, and a controller. MG1 generates a counter-electromotive torque when rotated by the engine. During an inverter-less running control where the inverter is put into a gate shut-off state and the engine is driven to cause MG1 to generate the counter-electromotive torque, the controller decreases a engine target rotation speed Netag when an integrated value of battery charging current (deterioration evaluation value D) is greater than a predetermined value (threshold value D1) smaller than the engine target rotation speed Netag when the deterioration evaluation value D is equal to or smaller than the threshold value D1.
