Abstract: PROBLEM TO BE SOLVED: To provide a vehicle control device capable of exactly calculating a rotational number by eliminating an influence of backlash between gears when calculating the rotational number by a gear of a power source. SOLUTION: The vehicle control device is applied to a vehicle which outputs power through at least one or more gears than that of the power source. The vehicle control device is an ECU, for example, and functions as a rotational number calculating means and a fluctuation inhibiting means. The rotational number calculating means calculates a gear rotational number by a gear of a power source on the basis of the rotational number of the power source. The fluctuation inhibiting means calculates a value in which fluctuation in the gear rotational number is inhibited on the basis of the gear rotational number calculated by the rotational number calculating means, and enlarges the degree of fluctuation inhibition when the fluctuation of the gear rotational number by the backlash between the gears is generated. Thus, even if the fluctuation in rotational number is generated by the backlash between the gears, the gear rotational number can be determined exactly by eliminating the influence caused by the backlash.
