Original Abstract Submitted
In an on-vehicle shutoff control device, a control unit switches a switch unit to an off state in a case where the switch unit is in the on state and a current value changes from less than a threshold value to the threshold value or more. The control unit switches the switch unit to the on state in at least one of a case where the switch unit has remained in the off state and a potential difference across the switch unit has been continuously maintained less than a reference for a predetermined period of time, a case where a speed of increase of potential difference across the switch unit is less than a reference, and a case where the potential difference across the switch unit is less than a reference at a time when a predetermined period of time passes after switching the switch unit to the off state.
