摘要： A transmission control system of an electric vehicle includes a motor configured to generate drive torque; a transmission configured to perform multi-stage shifting using a dog clutch in a restraint relationship with a one-way clutch configured to transmit forward power of the motor; a speed sensor configured to measure a rotation speed on an output side of the transmission; a motor control unit configured to control the drive torque from the motor according to a driver's accelerator position signal (APS) value; and a vehicle control unit configured to control the multi-stage shifting of the transmission according to a torque command based on the APS value, and to perform clutch alignment control by moving up a sleeve in a reverse direction to contact a hub through a reverse rotation operation of gear teeth by applying reverse rotation torque of predetermined drive force through the motor in a pre-engagement state of the dog clutch.
