Claim:
1. A shifting control method for a vehicle, comprising: a Wide Open Throttle (WOT) determination, by a controller, of determining whether the vehicle is in a WOT condition; a shift RPM determination, by the controller, of determining shift Revolution Per Minute (RPM) using turbine RPM and slip RPM, when it is determined in the WOT determination that the vehicle is in the WOT condition, wherein the turbine RPM is RPM of a turbine in a torque converter and the slip RPM is a difference of the turbine RPM and an engine RPM; an estimated RPM determination, by the controller, of determining estimated RPM based on the shift RPM and a rate of change of the turbine RPM after the shift RPM determination, the estimated RPM being the shift RPM after a preset time period; an estimated RPM comparison, by the controller, of comparing the estimated RPM with a first preset RPM after the estimated RPM determination; and a shifting processing, by the controller, of performing upshifting when the estimated RPM is equal to or greater than the first preset RPM as a result of the estimated RPM comparison.
