Abstract:
This road surface state detection system comprises a data acquisition unit 44, a road surface state estimation unit 45, and a site determination unit 46. The data acquisition unit 44 acquires travel data including vertical acceleration data for a vehicle and position data for the vehicle. The road surface state estimation unit 45 estimates the road surface state along the travel route of the vehicle on the basis of the acceleration data and position data for the vehicle. The site determination unit 46 determines whether there is an excluded site on the travel route of the vehicle. The road surface state estimation unit 45 omits the excluded site from road surface state estimation.
