A control device for a fuel injection valve including a variable lift mechanism of two or more stages is provided. The control device includes an inflection point detection unit for detecting an inflection point from at least one of a drive current when the fuel injection valve is opened or a drive voltage when the fuel injection valve is closed. The control device also includes a drive sensing unit for sensing a drive lift of the fuel injection valve from at least one of an inflection point of a drive current during valve opening operation or a drive voltage during valve closing operation. The control device is configured to limit the command drive lift when the sensed drive lift is different from a command drive lift.
A control device that controls a fuel injection valve including a variable lift mechanism that varies a lift amount of a valve body by a drive lift of two or more stages,
A control device that controls a fuel injection valve including a variable lift mechanism that varies a lift amount of a valve body by a drive lift of two or more stages, the control device comprising:
