  • Injection controller
    Patent number: 11181066
    Abstract: An injection controller includes a control IC outputting an energization instruction signal to apply a peak current to a fuel injection valve (i.e., an instruction TQ), and a current monitor unit detecting an electric current flowing in the fuel injection valve. The control IC corrects an output OFF time of the energization instruction signal based on a difference between (i) an integrated current of an ideal current profile which serves as a target current before reaching the peak current and (ii) an integrated current of an energization current in the fuel injection valve detected by the current monitor unit (i.e., an effective TQ).
