PROBLEM TO BE SOLVED: To provide a method for accurately predicting a road surface state on a place within a predetermined range.SOLUTION: In a road surface state prediction method, when predicting a road surface state of a place within a predetermined range, using a road surface estimation determination value which is calculated using vehicle information being information on behavior of a vehicle Wduring travel acquired by an on-vehicle sensor 11 mounted on the vehicle, or, using an estimation road surface state estimated by using the road surface estimation determination value, the road surface state on a place within the predetermined range is predicted on the basis of a time change of the road surface estimation determination value or a time change of the estimated estimation road surface state, calculated on the place within the predetermined range.SELECTED DRAWING: Figure 6
【課題】所定の範囲内の場所における路面状態を精度よく予測する方法を提供する。【解決手段】車両に搭載された車載センサ11により取得された、走行時の車両Wiの挙動の情報である車両情報を用いて演算される、路面推定判定値、もしくは、前記路面推定判定値を用いて推定された推定路面状態を用いて、所定範囲内の場所の路面状態を予測する際に、所定の範囲内の場所において演算された路面推定判定値、もしくは、推定された推定路面状態の時間変化から、前記所定の範囲内の場所における路面状態を予測するようにした。【選択図】図6
