Abstract
A control apparatus for a hybrid vehicle includes an engine that combusts fuel to generate power. A drive motor assists the engine power and selectively operates as a generator to generate electrical energy. A clutch is disposed between the engine and drive motor. A battery supplies electrical energy to the drive motor or is charged by the generated electrical energy. A DC converter transforms a DC from the battery. An electric supercharger supplies supercharged air to the engine. A controller determines an optimal air amount to maximize system efficiency based on a drive motor limited output value determined by a battery SOC, and determines an output drive motor power output and an output engine power output based on the optimal air amount when an atmospheric pressure is less than a predetermined pressure, intake temperature is greater than a predetermined temperature and the SOC is less than a predetermined value.
