Problems solved by technology

[0006] When the driving load of the vehicle is high (for example, when the vehicle is driven at an extremely high speed, when the vehicle is continuously driven on a sloped road, or when the vehicle is driven at a high altitude) and when the SOC of the battery is low, the vehicle is not driven When using only the output of the engine with the assistance of the motor, when not running, the running speed decreases, and due to the excessive output of the engine and high engine speed, the fuel efficiency and exhaust gas deteriorate

Abstract

The disclosure provides an apparatus and method for controlling a hybrid vehicle having electric superchargers. The apparatus includes an engine that generates power by combusting fuel; and a drive motor that supplements the power from the engine and operates selectively as an electric generator to produce electrical energy. A clutch is disposed between the engine and the drive motor and a batterysupplies electrical energy to the drive motor and is charged with the electrical energy produced by the drive motor. Multiple electric superchargers are installed in multiple intake lines through which outside air to be supplied into a combustion chamber of the engine flows. A controller determines an operation mode of the multiple electric superchargers based on required power of a driver and astate of charge (SOC) of the battery and adjusts the power output from the engine and the power output from the drive motor.
