Abstract:
An ECU includes an injection controller that performs a partial lift injection in which a fuel injection valve is drivingly opened by an injection pulse by which a lift amount of a valve body of the fuel injection valve does not reach a full lift position, a first calculation section that calculates a first parameter correlated with an amount of induced electromotive force generated by a magnetic flux change during movement of the valve body to a closed position after OFF of the injection pulse of the partial lift injection, a second calculation section that calculates, based on a time-series change of the induced electromotive force after OFF of the injection pulse of the partial lift injection, a second parameter correlated with a voltage inflection point generated with reaching of the valve body to the closed position, and a correction section that corrects a time length of the injection pulse based on the first parameter and the second parameter.

Claim (Index 2):
The fuel injection control device for an internal combustion engine according to  claim 1 , further comprising\n an acquisition unit that acquires a terminal voltage of the fuel injection valve, wherein the first calculation section subjects the terminal voltage to predetermined first smoothing processing, calculates a difference between a non-smoothed value of the terminal voltage that is not subjected to the first smoothing processing and a smoothed value of the terminal voltage that is subjected to the first smoothing processing as a first order difference, and calculates the first parameter based on the first order difference; and the second calculation section subjects the first order difference to predetermined second smoothing processing, calculates a difference between a non-smoothed value of the first order difference that is not subjected to the second smoothing processing and a smoothed value of the first order difference that is subjected to the second smoothing processing as a second order difference, and calculates the second parameter based on the second order difference.
