An apparatus and a method for controlling a hybrid vehicle are provided. 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 battery supplies 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 a state of charge (SOC) of the battery and adjusts the power output from the engine and the power output from the drive motor.

Apparatus and method for controlling hybrid vehicle having electric superchargers

An apparatus of controlling a hybrid vehicle includes: an engine configured to generate power by combustion of fuel; a driving motor configured to assist power of the engine and selectively operate as a power generator to generate electric energy; an HSG configured to start the engine and selectively operate as a power generator to generate electric energy; a clutch provided between the engine and the driving motor; a battery configured to supply electric energy to the driving motor or charge electric energy generated in the driving motor; an EGR apparatus configured to resupply exhaust gas discharged from the engine to the engine; an electric supercharger in which outside air supplied to combustion chambers flows; and a controller configured to variably control a travelling mode, an operating point, a lock charge through the driving motor and the HSG, and a shifting pattern based on a required torque of a driver and a SOC of the battery.
