  "textContent": "An electronic control unit (ECU) (5) of a fuel injection system of an internal combustion engine stores correspondences defining each correspondence between an operating state and a correction value for each progression level of a change in the engine with time in advance. The ECU (5) determines which progression level includes a present state of the change in the engine with time and selects the correspondence based on a result of the determination. Thus, even if a change in an error with time, which should be corrected, does not have an identical tendency corresponding to the operating state, the error can be suitably corrected by referring to the correspondence between the operating state and the correction value in each progression level.",
