PURPOSE: An automatic manual transmission of a hybrid vehicle is provided to remove the dissatisfaction of customers and improve driving properties of the vehicle by preventing the sense of disconnecting torque while the vehicle changes speed. CONSTITUTION: An automatic manual transmission of a hybrid vehicle includes an input shaft (10), an output shaft (20), a differential (30), a plurality of synchronizers (40), a speed sensor (50), a transmission assist unit (60), and a control unit (70). The input shaft includes a plurality of driving gears (G1, G2,G3,G4,G5), and a main clutch (15) is arranged in between an engine (E) and the input shaft in order to disconnect power. The output shaft is aligned with the input shaft and includes a plurality of driven gears (P1,P2,P3,P4,P5). The differential is connected to the output shaft and transmits the power to a driving wheel on both sides by drawing the power which is used for changing speed. The synchronizer selectively fixes one among the driven gears to the output shaft. The speed sensor is installed in the driving wheel and measures the speed of the vehicle. The transmission assist unit supplies the power of a motor (65) to the output shaft while the power of the engine is disconnected as a main clutch is turned off when the speed of the vehicle is changed. The control unit electrically connects the speed sensor and the transmission assist unit and controls torque of the motor of the transmission assist unit according to the speed of the vehicle. |
