To acquire temperature in an inner surface of a dump body.SOLUTION: Provided is a state estimation system of a dump truck including an engine and a dump body. The dump body includes a flow path through which exhaust gas discharged from the engine circulates. A cargo is loaded in the dump body. The state estimation system includes: an exhaust gas flow rate acquisition unit that acquires an exhaust gas flow rate indicating detection data of the flow rate of the exhaust gas flowing in the flow path; an exhaust gas temperature acquisition unit that acquires exhaust gas temperature indicating detection data of temperature of the exhaust gas flowing in the flow path; and a body temperature estimation unit that estimates body temperature indicating temperature at a predetermined portion in the inner surface of the dump body that is in contact with the cargo on the basis of the exhaust gas flow rate and the exhaust gas temperature.SELECTED DRAWING: Figure 6
【課題】ダンプボディの内面の温度を取得すること。【解決手段】エンジンとエンジンから排出された排ガスが流通する流路を有し積荷が積載されるダンプボディとを備えるダンプトラックの状態推定システムは、流路に流入する排ガスの流量の検出データを示す排ガス流量を取得する排ガス流量取得部と、流路に流入する排ガスの温度の検出データを示す排ガス温度を取得する排ガス温度取得部と、排ガス流量と排ガス温度とに基づいて、積荷と接触するダンプボディの内面の所定部位の温度を示すボディ温度を推定するボディ温度推定部と、を備える。【選択図】図6
