Method and system for controlling a vehicle

The invention relates to a method and a system for controlling a vehicle, wherein, at the time of shifting from one gear train among a plurality of gear trains to another gear train, a transmission for controlling a transfer torque variable mechanism and supplementing torque during shifting, during a period of transferring at least a part of torque of an engine (1) by the transfer torque variable means (203, 204), controls so as to generate engine torque larger than engine torque before the period at least once and carries out shifting.
