摘要： A method of controlling an electric vehicle transmission includes: a torque-securing step of securing a predetermined spare torque to be generated by a motor in accordance with a current motor torque when a controller determines that there is a need for downshift from an upper gear step to a lower gear step; a slip-controlling step of generating a friction force through a servo clutch applying a friction force between an input shaft and a servo driving gear of a pair of servo gears; a shifting-to-neutral step of shifting to a neutral gear by disengaging a synchronizer for the upper gear step; a motor-synchronizing step of synchronizing a rotational speed of the motor with a desired speed of a lower gear step using the spare torque of the motor secured in the torque-securing step; a gear-engaging step of engaging a synchronizer for the lower gear step; and a clutch-disengaging step of finishing shifting by disengaging the servo clutch.
