    Abstract: During a hybrid drive, a hybrid vehicle sets an engine required power based on a driving required power and controls an engine to output the engine required power, while controlling a motor to drive the hybrid vehicle with the driving required power. When a catalyst temperature of an exhaust emission control device is equal to or lower than a predetermined temperature that requires warming up, in the state that an output upper limit power which a power storage device is allowed to output is equal to or larger than a predetermined power, the hybrid vehicle sets a power calculated by subtracting the output upper limit power from the driving required power, to the engine required power. In the state that the output upper limit power is smaller than the predetermined power, the hybrid vehicle sets the driving required power to the engine required power.

    Abstract: A vehicle includes a display device that displays information indicating an operation state of an internal combustion engine. A display control device which is a control device that controls the display device includes an acquisition unit configured to acquire the operation state of the internal combustion engine. The display control device includes a display control unit that switches information which is displayed on the display device between a warm-up indicator for notifying that warm-up of the internal combustion engine is being performed and a warm-up completion indicator for notifying that warm-up of the internal combustion engine has been completed. The display control unit is configured to prohibit switching from the warm-up completion indicator to the warm-up indicator when the warm-up completion indicator is being displayed on the display device while the internal combustion engine is operating.

    Abstract: During acceleration in accordance with an operation of an accelerator pedal in HV traveling, an ECU performs engine rotation speed control for increasing an engine rotation speed in accordance with acceleration of a vehicle, by increasing discharge power of a power storage device to increase driving force of a motor generator and suppressing an output from an engine. The discharge power of the power storage device at the time when performing engine rotation speed control in a CD mode is greater than the discharge power at the time when performing engine rotation speed control in a CS mode.
