This state estimation system is a state estimation system for a dump truck provided with an engine and a dump truck body having a flow path through which exhaust gas discharged from the engine flows and on which goods are loaded, the state estimation system being provided with: an exhaust gas flow rate acquisition unit that acquires an exhaust gas flow rate; the exhaust gas flow rate acquisition unit acquires exhaust gas flow rate of detection data indicating flow rate of exhaust gas flowing into a flow path. An exhaust gas temperature acquisition unit that acquires an exhaust gas temperature of detection data indicating the temperature of the exhaust gas flowing into the flow path; and a vehicle body temperature estimation unit that estimates, on the basis of the exhaust gas flow rate and the exhaust gas temperature, a vehicle body temperature indicating the temperature of a predetermined portion of the inner surface of the unloading vehicle body that is in contact with the cargo.

    本发明的状态推断系统是自卸车的状态推断系统,该自卸车具备发动机、以及具有供从发动机排出的废气流通的流路且装载货物的卸料车体,该状态推断系统具备:废气流量取得部,其取得表示流入流路的废气的流量的检测数据的废气流量;废气温度取得部,其取得表示流入流路的废气的温度的检测数据的废气温度;以及车体温度推断部,其基于废气流量和废气温度,推断表示与货物接触的卸料车体的内表面的规定部位的温度的车体温度。
