Title (EN) ROAD SURFACE CONDITION ESTIMATION DEVICE
(FR) DISPOSITIF D'ESTIMATION D'ÉTAT DE SURFACE DE ROUTE
(JA) 路面状態推定装置
Abstract:
(EN) When information relating to road surface conditions is conveyed from a vehicle body-side system (2) to tire mount sensors (1), and the tire mount sensors (1) determine the road surface conditions, an integrated voltage value is corrected on the basis of the information relating to the road surface conditions. Road surface conditions can thereby be more accurately estimated. Furthermore, inasmuch as road surface conditions can be estimated at each tire mount sensor (1), road surface conditions can be estimated for each wheel.
(FR) Selon l'invention, lorsque des informations se rapportant à des états de surface de route sont transmises à partir d'un système côté carrosserie de véhicule (2) à des capteurs de montage de pneu (1) et que les capteurs de montage de pneu (1) déterminent les états de surface de route, une valeur de tension intégrée est corrigée sur la base des informations se rapportant aux états de surface de route. Des états de surface de route peuvent ainsi être estimés de manière précise. En outre, dans la mesure où des états de surface de route peuvent être estimés au niveau de chaque capteur de montage de pneu (1), des états de surface de route peuvent être estimés pour chaque roue.
(JA) 車体側システム(2)からタイヤマウントセンサ(1)に路面状態に関係する情報を伝え、タイヤマウントセンサ(1)が路面状態の判定を行うときに、路面状態に関係する情報に基づいて積分電圧値を補正する。これにより、より的確に路面状態を推定することが可能となる。また、各タイヤマウントセンサ(1)において、路面状態を推定できることから、1輪毎に路面状態を推定することが可能となる。
