Pm amount estimation device, pm amount estimation system, pm amount estimating method, data analysis device, control device for internal combustion engine, and receiver

A PM amount estimation device comprising:

• a storage device;
• and
• an execution device, wherein
• the PM amount estimation device is applied to a filter that collects PM from exhaust gas discharged to an exhaust passage of an internal combustion engine,
• the storage device is configured to store mapping data that is data defining a mapping that outputs a PM amount collected by the filter, the mapping having a flow rate variable and at least one of an intake air temperature variable and a wall surface variable as an input, the intake air temperature variable being a variable related to a temperature of air drawn into the internal combustion engine, the wall surface variable being a variable related to a cylinder wall surface temperature of the internal combustion engine, and the flow rate variable being a variable indicating a flow rate of a fluid entering the filter, and
• the execution device is configured to execute:
• an acquiring process for acquiring the flow rate variable and at least one of the intake air temperature variable and the wall surface variable,
• a PM amount calculation process for calculating the PM amount based on the output of the mapping having the data acquired by the acquiring process as the input, and
• an operation process for operating predetermined hardware in accordance with the PM amount.
