To suitably estimate a state of a vehicle.SOLUTION: A vehicle state estimation part 1200 comprises a main calculation part 1210 which performs calculation for a state quantity concerning a vehicle state. An input value to the main calculation part 1210 includes ground load fluctuation of a wheel. The ground load fluctuation of the wheel is calculated with reference to a map with a tire effective radius R, which is calculated by a wheel effective radius calculation part in a tire ground load fluctuation calculation part 1220 as an input and with a ground load with an output.SELECTED DRAWING: Figure 5
【課題】車両の状態を好適に推定する。【解決手段】車両状態推定部1200は、車両状態に関する状態量についての演算を行う主演算部1210を備えており、主演算部1210への入力値には、車輪の接地荷重変動が含まれる。当該車輪の接地荷重変動は、タイヤ接地荷重変動算出部1220中の車輪有効半径算出部が算出したタイヤ有効半径Reを入力とし接地荷重を出力とするマップを参照して算出される。【選択図】図5
