Cutoff control apparatus having a first cutoff unit and a second cutoff unit

A cutoff control apparatus configured to control a cutoff unit in a vehicle-mounted system, the vehicle-mounted system including:

• a power storage unit;
• a power line, which is a line through which power is transferred between the power storage unit and a load;
• and the cutoff unit that switches between a cutoff state that cuts off supplying of power from the power storage unit side to the load side on the power line and a canceled state where the cutoff state is canceled,
• wherein in the vehicle-mounted system, the cutoff unit includes a first cutoff unit and a second cutoff unit, and the second cutoff unit enters the cutoff state when a first overcurrent state has occurred on the power line when the first cutoff unit is in the canceled state, and
• the cutoff control apparatus comprises a control apparatus for instructing the first cutoff unit to switch to the cutoff state when the power line is in a second overcurrent state, and
• wherein a magnitude of a current flowing through the power line in the first overcurrent state is equal to or greater than a first threshold,
• a magnitude of a current flowing through the power line in the second overcurrent state is equal to or greater than a second threshold, and
• the first threshold is smaller than the second threshold.

• wherein the control apparatus includes a first apparatus and a second apparatus,
• the first apparatus switches the first cutoff unit to the cutoff state when a collision detection sensor has given notification of a collision of a vehicle or when the second overcurrent state has occurred, and
• the second apparatus switches the second cutoff unit to the cutoff state when the first overcurrent state has occurred.
