Abstract
A shift control method for an automated manual transmission (AMT) of a vehicle includes: when a shift operation is started, a torque of the second motor is increased so that a change in an output torque of the output shaft due to a change in a torque of the first motor is minimized while the torque of the first motor is being decreased. According to the shift control method, the increased torque of the second motor is maintained to be constant while controlling transmission release, speed synchronization, and transmission coupling. After the control over the transmission coupling is completed, the torque of the second motor is controlled so that the output torque of the output shaft follows a predetermined target torque while the torque of the first motor is controlled to be increased.
