FUEL INJECTION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

WIPO Patent Application WO/2021/172382

A1

An ECU (50) is equipped with: a first acquisition unit for acquiring a dynamic parameter when fuel injection is carried out by a fuel injection valve (30); a second acquisition unit for acquiring an injection amount parameter when fuel injection is carried out by the fuel injection valve (30); a first calculation unit for calculating a dynamic correction value for compensating for deviation in an operation characteristic of the valve body on the basis of the dynamic parameter; a second calculation unit for calculating an injection amount correction value for compensating for deviation in an injection amount relative to an energization command signal on the basis of the injection amount parameter; and a correction unit for using the dynamic correction value calculated by the first calculation unit and the injection amount correction value calculated by the second calculation unit to correct the mode of implementation of the fuel injection. The second calculation unit calculates the injection amount correction value under a condition in which a fuel injection correction has been implemented on the basis of the dynamic correction value.
