摘要： 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.

摘要： 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.

摘要： An apparatus of controlling a vehicle and a method thereof are provided. The operating region of an engine is operated with theoretical air-fuel ratio. The apparatus includes a supercharger that supplies compressed air to a the combustion chamber of the engine and a spark plug that ignites mixed air supplied to the combustion chamber. An intake valve selectively opens and closes the combustion chamber for inflowing the mixed air therein. A variable valve apparatus adjusts an opening timing and closing timing of the intake valve and a controller adjusts an ignition timing of the spark plug and the closing timing of the intake valve through the variable valve apparatus based on the operating region of the engine.
