Abstract
A control device includes a difference calculating unit configured to generate a difference waveform composed of the difference between a normal operation waveform, which is a voltage waveform of the fuel injection valve at a time that the fuel injection valve is operating, and a non-operation waveform, which is a voltage waveform of the fuel injection valve at a time that the fuel injection valve is not operating, a derivative calculating unit configured to generate a differentiated waveform obtained by differentiating the difference waveform, and an operating state determining unit configured to determine the operating state of the fuel injection valve based on the differentiated waveform.
