Abstract
A control system of a hybrid vehicle includes: an engine that generates power by burning fuel; a driving motor that assists the power from the engine by generating power using electricity supplied from a battery; an integrated starter-generator that starts the engine and charges the battery by operating selectively as a power generator; an atmospheric sensor that measures the atmospheric pressure; a temperature sensor that measures the temperature of intake air flowing into the engine; and a controller that calculates a control factor, using the atmospheric pressure measured by the atmospheric sensor and the temperature of intake air measured by the temperature sensor, and adjusts a State of Charge (SOC) charge band between an SOC where charging the battery is started and an SOC where a hybrid vehicle runs in a charge mode, in accordance with the magnitude of the control mode.
