Abstract

The application relates to an apparatus for controlling a hybrid vehicle having an electric supercharger and a method thereof. 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 provided between the engine and the drive motor. A battery supplies electric energy to the driving motor or is charged by the generated electric energy. A DC converter converts DC from a battery. The electric supercharger supplies charge air to the engine. The controller determines an optimal amount of air that maximizes system efficiency based on the drive motor limited output value determined by the battery SOC, and determines a drive motor power output and an engine power output based on the optimal amount of air when the air pressure is less than a predetermined pressure, the intake air temperature is less than a predetermined temperature, and the SOC is less than a predetermined value.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0127695 filed on October 15, 2019, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to an apparatus for controlling a hybrid vehicle including an electric supercharger, and more particularly, to an apparatus for controlling a hybrid vehicle to determine an optimum operating line of an engine when the output of a drive motor is limited by the state of charge of the battery and method. Background technique [0004] A hybrid vehicle is a vehicle that uses two or more power sources, and generally refers to a hybrid electric vehicle driven by an engine and an electric motor. Hybrid electric vehicles may form various configurations using two or more power sources including an engine and an electric motor. Typically, hybrid electric vehicles use a powertrain in the...
