Abstract
A control device of a vehicle with a stepped automatic transmission has: a gradient acquiring part; a driving force calculating part; a future change estimating part; and a shift control part. The shift control part prohibits change of the gear stage when the speed of change of the speed or acceleration of the vehicle in the future if the maximum driving force applied, is within a reference range of speed of change where the occupants would not notice a change in speed or acceleration, and permits change of the gear stage when the speed of change of the speed or acceleration of the vehicle in the future if the maximum driving force applied, is outside the reference range of speed of change.
