Abstract
A cutoff control device controls a cutoff unit. An in-vehicle system includes a power storage unit, a power line for power transmission between the power storage unit and a load, and a cutoff unit to switch between allowing and cutting off power supply from the power storage unit to the load through the power line. The cutoff control device includes a current detection unit, a voltage detection unit, and a control unit. The current detection unit detects the current flowing through the power line. The voltage detection unit detects the voltage in the power line. The control unit instructs the cutoff unit to cut off power if the current detection unit detects a predetermined current increase and the voltage detection unit detects a predetermined voltage decrease.
Claims9
A cutoff control device that is for use in an in-vehicle system including:
- a power storage unit;
- a power line as a path through which power is transmitted between the power storage unit and a load;
- and a cutoff unit configured to switch from an allowed state in which power supply from the power storage unit to the load through the power line is allowed to a cutoff state in which the power supply is cut off, and that is configured to control the cutoff unit, the cutoff control device comprising:
- a current detection unit configured to detect a current state of a current flowing through the power line;
- a voltage detection unit configured to detect a voltage state of a voltage in the power line;
- and
- a control unit configured to instruct the cutoff unit to switch to the cutoff state if the current state detected by the current detection unit is a predetermined current increase state and the voltage state detected by the voltage detection unit is a predetermined voltage decrease state.
