Claim 0:
1. An apparatus for controlling a transmission of a vehicle, the apparatus comprising:
a determination device configured to determine whether a condition for a regenerative braking based lift foot up shift is satisfied;
a controller configured to perform regenerative brake control and perform a shift by controlling release clutch torque and lock-up clutch torque, when the condition for the regenerative braking based lift foot up shift is satisfied; and
a torque compensation device configured to compensate for the release clutch torque according to an RPM variation during the shift;
wherein the torque compensation device is configured to:
compare a target RPM variation and an input RPM variation during the shift;
compensate for the release clutch torque to increase the release clutch torque by a first compensation value when the target RPM variation is greater than the input RPM variation; and
compensate for the release clutch torque to decrease the release clutch torque by a first compensation value when the target RPM variation is less than or equal to the input RPM variation wherein the controller is configured to determine the release clutch torque by applying a compensation value to an input torque value.
