Abstract
A method for controlling revolutions per minute (RPM) flare, in which an RPM of a transmission increases due to clutch slip, for a hybrid vehicle can include: determining whether gear-shifting is performed in a transmission of the hybrid vehicle; detecting whether RPM flare of the transmission occurs when it is determined that the gear-shifting is performed; and controlling a torque of a motor of the hybrid vehicle so as to reduce the RPM flare of the transmission by reducing the torque of the motor when the RPM flare of the transmission is detected.
