Abstract

A method including acquiring a first test pattern in which an operation variable for an engine test is changed in time series, inputting a first operation variable to a mathematical model representing a time series response obtained by inputting a test pattern as a simulation of the engine test, monitoring a first monitoring parameter obtained by inputting the first operation variable to the mathematical model, holding the first operation variable until the first monitoring parameter is less than a first threshold value, creating a history of the first operation variable in the simulation as a second test pattern, monitoring a second monitoring parameter obtained by inputting a second operation variable to a real engine based on the second test pattern, holding the second operation variable until the second monitoring parameter is less than a second threshold value, acquiring time series data of the second operation variable and a controlled variable.
