Injection control device

An injection control device that controls fuel injection by driving a fuel injection valve that supplies fuel to an internal combustion engine with an electric current, the injection control device comprising:

• an instruction output unit outputting an instruction energization time that is an instruction value of the energization time of the fuel injection valve corresponding to a target injection amount that is a target value of a fuel injection amount of the fuel injection valve;
• an energization controller controlling energization of the fuel injection valve based on the instruction energization time;
• an area corrector correcting an area of the electric current flowing through the fuel injection valve when the fuel injection valve is driven by the electric current, calculating a correction time of the energization time, and correcting the instruction energization time;
• an abnormality determiner determining that an abnormality related to the area correction has occurred when the correction time reaches a predetermined upper limit value;
• and
• a normal-return determiner executing, after the abnormality determiner determines that the abnormality related to the area correction has occurred, a normal-return determination at an execution timing of when a degree of influence of the abnormality on an emission becomes equal to or less than a predetermined value, the normal-return determination executed to determine whether or not an abnormal state in which the abnormality related to the area correction has been caused has returned to a normal state.
