Abstract
This vehicle control deviceis provided with: a current gear stage selection unitwhich, on the basis of the travel resistance of the vehicle, selects a current gear stage, which is the gear stage of the vehicle in the current travel segment where the vehicle is traveling; a next gear stage selection unitwhich selects a next gear stage, which will be the gear stage of the vehicle in the next travel segment, forwards in the travel direction of the vehicle, having a road slope different from that of the current travel segment; and a shift control unitwhich, if during travel of the vehicle in the current travel segment in the current gear stage, the current gear stage selection unithas newly selected a target gear stage higher than the next gear stage, controls shifting such that upshifting from the current gear stage to the target gear stage is suppressed and the current gear stage is maintained. If, in a state in which upshifting is suppressed, the engine rotation speed reaches or exceeds a prescribed value during travel in the current travel segment, the shift control unitcontrols shifting so as to upshift to the target gear stage without suppression of upshifting.
