Abstract
An apparatus for controlling a hybrid vehicle may include an engine that generates driving torque by combustion of fuel; an integrated starter-generator that starts the engine and generates electrical energy by selectively operating as a power generator; a drive motor that supports the power of the engine and generates electrical energy by selectively operating as a power generator; a battery that charges with the electrical energy generated by the integrated starter-generator and the drive motor; a nitrogen oxide purification device (LNT) that purifies nitrogen oxide included in exhaust gas exhausted from the engine; and a controller that controls engine torque by calculating a target engine torque for regenerating the nitrogen oxide purification device, supports the engine torque through the integrated starter-generator or the drive motor when a driving torque necessary for driving is greater than the target engine torque at a regeneration mode of the nitrogen oxide purification device, and performs regenerative braking the driving torque through the integrated starter-generator or the drive motor when the driving torque is less than the target engine torque.
