APPARATUS FOR CONTROLLING STATE OF CHARGE OF HYBRID VEHICLE AND METHOD USING THE SAME

An apparatus for controlling a SOC of a hybrid vehicle comprises a data detector (10) for detecting data including a SOC of a battery, a vehicle speed, an amount of operating of a brake pedal sensor, an amount of operating of an acceleration pedal sensor (14), and a driving state of a vehicle to control a SOC of a hybrid vehicle. Included are a correction value calculating unit (20) configured for calculating a correction value of the SOC based on the data; a SOC calculating unit (30) configured for calculating a virtual center SOC (L1) based on the correction value of the SOC and an actual SOC; and an engine-on/off determining unit (40) configured for determining whether an engine is turned on or turned off based on the virtual center SOC (L1).
