To provide a tire condition determination device capable of determining whether the tires of a vehicle are properly inflated for each vehicle traveling on a road.SOLUTION: Each of the plural input units receives measurement signals from sensors, in which the force exerted by the tires of a vehicle traveling on a road surface is measured. A first calculation unit calculates the contact length between the tire with the ground based on the measurement signal of the pressure in the vehicle driving direction applied by the tire to the contact length with the ground, input to the input unit and the speed of the vehicle acquired by a speed acquisition unit. A determination unit determines whether the tire pressure is proper based on the contact length with the ground of the tire calculated by the first calculation unit.SELECTED DRAWING: Figure 3

    【課題】道路を走行している車両毎に、その車両のタイヤの空気圧が適正であるかどうかを判定する。【解決手段】入力部には、走行路を走行している車両のタイヤが路面を押圧する押圧力を計測したセンサの計測信号が入力される。第1算出部が、入力部に入力されたタイヤが路面を押圧する押圧力の計測信号と、速度取得部が取得した車両の速度を基に、車両の走行方向におけるタイヤと路面との接地長さを算出する。判定部が、第1算出部が算出したタイヤの接地長さを基に、タイヤの空気圧が適正であるかどうかを判定する。【選択図】図3
