Abstract
An apparatus for controlling a SOC of a hybrid vehicle comprises a data detector 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, and a driving state of a vehicle to control a SOC of a hybrid vehicle. Included are a correction value calculating unit configured for calculating a correction value of the SOC based on the data; a SOC calculating unit configured for calculating a virtual center SOC based on the correction value of the SOC and an actual SOC; and an engine-on/off determining unit configured for determining whether an engine is turned on or turned off based on the virtual center SOC.
