PURPOSE : A re-acceleration response improving method of hybrid vehicle is provided to reduce the synchronization time by reducing response delay in proportion to speed difference between engine and motor before the engine clutch coupling by making eng. target speed to present motor speed so engine and motor speed make synchronization state all the time when removing engine clutch. CONSTITUTION : The re-acceleration response improving method of hybrid vehicle includes the steps of : judging the state of engine rotation and whether engine clutch is removed after setting up the eng. target speed; judging whether engine satisfies idle state in the engine clutch removal state; and uniting the engine target speed to actual motor speed when the engine clutch is removed and at the same time in the state of idle. When the engine clutch is not removed and engine is not the state of idle, unite the eng. target speed to eng. target idle speed.
