Abstract
A vehicle control system 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. The vehicle control system includes 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 because of a driver's driving operation or the influence of a running road surface.
Claims8
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.
