Claim 6:
7. A method for controlling a transmission of a vehicle, the method comprising:
determining, by a determination device, whether a condition for a regenerative braking based lift foot up shift is satisfied;
performing regenerative brake control, by a controller, when the condition for the regenerative braking based lift foot up shift is satisfied;
performing a shift, by the controller, by controlling release clutch torque and lock-up clutch torque; and
compensating for the release clutch torque, by a torque compensation device, according to an RPM variation during the shift;
wherein the compensating of the release clutch torque includes:
comparing a target RPM variation and an input RPM variation during the shift;
compensating 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
compensating 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.
