Hybrid vehicle

A hybrid vehicle comprising:

• an engine including a plurality of cylinders configured to generate a driving torque by burning fuel;
• a drive motor configured to generate a driving torque using electric energy supplied from a battery and assist the driving torque of the engine;
• an engine clutch disposed between the engine and the drive motor, and configured to selectively connect the engine to the drive motor;
• a first intake valve disposed in a first intake line in which intake air supplied to a combustion chamber flows;
• a second intake valve disposed in a second intake line in which intake air supplied to the combustion chamber flows;
• a first electric supercharger disposed in the first intake line;
• a second electric supercharger disposed in the second intake line;
• a connecting valve disposed in a connecting line configured to connect the first intake line to the second intake line;
• and
• a controller configured to determine an operating mode among a plurality of operating modes of the first and the second electric superchargers based on a pressure ratio and a flow rate of the intake air supplied by each of the first and the second electric superchargers,
• wherein
• the plurality of operating modes include a single mode, a serial mode, and a parallel mode, and
• wherein:
• in the single mode, intake air compressed by one of the first and second electric superchargers is supplied to the combustion chamber,
• in the serial mode, intake air compressed in series by the first electric supercharger and the second electric supercharger is supplied to the combustion chamber, and
• in the parallel mode, intake air compressed in parallel by the first electric supercharger and intake air compressed by the second electric supercharger, respectively, are supplied to the combustion chamber.
