PURPOSE: A controlling method and apparatus of a driving gear unit is provided to prevent damages of components due to operation of a motor during shifting a gear, and to maintain a driving motor speed synchronization and vehicle speed for shifting by cooperation control between a driving gear control device and an MCU(micro controller unit). CONSTITUTION: A controlling method and apparatus of a driving gear unit comprises a step of detecting a location of a gearshift, and transmitting the HCU(hybrid control unit) to a driving gear control apparatus. In order to prevent damages of components during operation of a motor during shifting a gear, cooperation control between a driving gear control device and an MCU(micro controller unit) are conducted. The gear is shifted by controlling the driving gear control device. Inspection whether the gear shifting is normally finished is conducted. The driving gear control device comprises a driving gear, a driving motor, MCU, a control part, and HCU. The MCU controls the driving motor. The HCU searches the location of a gearshift, and transmits the order for shifting gear to a control part.
