Abstract
A shift control method and apparatus for a vehicle is described. The shift control method for a vehicle having an oil pump includes determining whether the vehicle satisfies an Idle Stop and Go (ISG) learning condition, measuring, when the vehicle satisfies the ISG learning condition, a shift time of a transmission when a driving state of the vehicle is changed from an idling state to a restart state, comparing the measured shift time with a predetermined reference shift time, and adjusting a pressure of oil supplied to a solenoid of the transmission from the oil pump according to the compared result. Thus, it is possible to reduce a variation in shift time required when the ISG vehicle using a mechanical oil pump in place of an electrical oil pump is restarted.
