A method and system for shift control in an automatic transmission for a vehicle, wherein, during shifting, engine torque is changed to thereby maintain the shift characteristics satisfactorily, and wherein at least engine torque control in association with 1st shifting is stopped when a 2nd shifting command is emitted before 1st shifting is completed. When only the engine torque control in association with 1st shifting is stopped, thereafter, only the engine torque control in association with 2nd shifting can be performed, so that unnecessary torque control can be dispensed with. Furthermore, when engine torque controls in association with not only the 1st shifting but also the 2nd shifting are stopped, an unnecessary change in the engine torque control can be dispensed with in the case of shifting in which the shifting operation is not substantially performed.
A method of shift control in an automatic transmission for a vehicle, wherein, during shifting, engine torque is changed by a predetermined value to thereby maintain the shift characteristics satisfactorily, which comprises:
