1. A vehicle control system that obtains an index indicating a running condition of a vehicle on the basis of a vehicle parameter indicating a motion of the vehicle and then sets a running characteristic of the vehicle in accordance with the index, comprising: a noise reduction unit that is configured to obtain the index on the basis of the vehicle parameter of which a fluctuating component that fluctuates due to a condition of a running road surface is attenuated,wherein the noise reduction unit is configured to attenuate a noise component of a predetermined frequency that falls within a predetermined frequency band of the fluctuating component by filtering the fluctuating component using a band-pass filter having a predetermined frequency characteristic, in order to suppress an influence of a noise of the fluctuating component on a resultant index. 2. The vehicle control system according to claim 1, wherein the vehicle parameter includes an acceleration of the vehicle. 3. The vehicle control system according to claim 1, wherein the noise reduction unit is configured to attenuate a noise component of a predetermined frequency in the fluctuating component. 4. The vehicle control system according to claim 1, wherein the filter used in the noise reduction unit is the same filter as that used in a unit other than the noise reduction unit. 5. The vehicle control system according to claim 1, wherein the filter used in the noise reduction unit is different from a filter used in a unit other than the noise reduction unit. 6. The vehicle control system according to claim 1, wherein in the filter used in the noise reduction unit, a filter characteristic for a component in a longitudinal direction of the vehicle is different from a filter characteristic for a component in a lateral direction of the vehicle. 7. The vehicle control system according to claim 1, wherein the filter used in the noise reduction unit has a filter characteristic that is varied in accordance with a speed range of the vehicle. 8. The vehicle control system according to claim 2, wherein the noise reduction unit is configured to attenuate a noise component of a predetermined frequency in the fluctuating component.
