Problems solved by technology

Specifically, when the driving load of the vehicle is large (for example, when the vehicle is driving on a high ground, when the vehicle is running under a long downhill load, when the vehicle is connected with a large load, when the outside temperature is very high or very low, limiting the output of the battery, etc.), when the engine operating point of the engine is not properly adjusted, the vehicle operates in a high engine revolutions per minute (RPM) region, reducing engine efficiency and reducing fuel efficiency
In addition, under high load conditions, when the power of the engine is continuously assisted by the drive motor to meet driving conditions, the drive motor may not be able to prevent the battery's SOC from dropping sharply

Abstract

An apparatus for controlling a hybrid vehicle is provided. The apparatus includes an engine generating power by combustion of fuel, a driving motor assisting power of the engine and selectively operated as a power generator to generate electric energy and a clutch disposed between the engine and the driving motor. A battery supplies electric energy to the driving motor and charges the electric energy generated in the driving motor. A plurality of electric superchargers are installed in a plurality of intake lines, in which outside air supplied to combustion chambers of the engine flows, respectively and a controller variably adjusts an operating point of the engine.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0152445 filed on November 25, 2019, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an apparatus and method of controlling a hybrid vehicle, and more particularly, to an apparatus and method of controlling a hybrid vehicle including an engine having a plurality of electric superchargers. Background technique [0004] A hybrid vehicle is a vehicle that uses two or more types of power sources, and generally refers to a hybrid electric vehicle that is driven using an engine and an electric motor. A hybrid electric vehicle may form various structures by using two or more types of power sources including an engine and a motor. Typically, hybrid electric vehicles employ a power train in a transmission-mounted electrical device (TMED) scheme in which a drive moto...
