To provide a shift control method and a shift control system capable of suppressing occurrence of slip of a drive wheel in drive force compensation processing during shift.SOLUTION: A shift control method executes, during shift of one transmission, drive force compensation processing for compensating for drive force loss in one drive wheel 11 provided with a transmission 16 by compensation driving force from another drive wheel. The shift control method includes the steps of: setting, as a basic value of an upper limit of the compensation drive force, basic upper limit compensation driving force defined from a viewpoint of minimizing difference between required driving force for a vehicle during the drive force compensation processing and driving force of the other driving wheel; and when a slip of the other driving wheel is detected during shift or occurrence of the slip is predicted, changing the upper limit of the compensation driving force from the basic upper limit compensation driving force to limited upper limit compensation driving force smaller than the basic upper limit compensation driving force, where the limited upper limit compensation driving force is determined as the compensation driving force when the slip of the driving wheels is detected or predicted.SELECTED DRAWING: Figure 3
