Abstract

A shift control device for a vehicle, includes: a minimum vehicle speed calculator that, when it is determined that a vehicle on traveling needs to decelerate before the vehicle arrives at a forward predetermined point, calculates a minimum vehicle speed using the periphery information; a shift position determination unit that determines a target shift position; and a downshift controller that, when the minimum vehicle speed is calculated, commences a downshift from a current shift position to the target shift position. Further, the downshift controller implements first control of performing multiple downshifts from the current shift position to the target shift position such that shift timing is provided at regular intervals, or second control of performing multiple downshifts such that rotational speeds of the engine after the respective downshifts become equal to each other.
