Abstract

This vehicle control deviceis provided with: a current gear stage selection unitwhich selects a current gear stage, which is the gear stage of the vehicle in the present travel state; a travel segment determination unitwhich determines the next travel segment forwards in the direction of travel of the vehicle V; and a shift control unitwhich, in the case that the current gear stage selection unithas newly selected a target gear stage lower than the current gear stage during travel of the vehicle V in the current gear stage in the current travel segment, if the next travel segment can be traveled in the current gear stage and the amount the vehicle V will lose speed after traveling the current travel segment is less than or equal to a prescribed threshold value, controls shifting of the gear stage such that downshifting from the current gear stage to the target gear stage is suppressed and the current gear stage is maintained. Even in a state in which downshifting is suppressed, if the state of the vehicle the satisfies a prescribed condition, then the shift control unitcontrols shifting of the gear stage so as to downshift to the target gear stage without suppression of downshifting.
