摘要： An electromagnetic valve control unit for detecting operation of an electromagnetic valve on the basis of a drive voltage or a drive current applied to the electromagnetic valve. The electromagnetic valve control unit includes an A/D converter, a filter, and a detection unit. The A/D converter converts the drive voltage or the drive current into a digital signal. The filter has a gain of about zero at a predetermined frequency. The detection unit detects operation of the electromagnetic valve on the basis of an output of the filter upon input of the digital signal into the filter.
