Abstract: A power supply control device for a vehicle controls power supply to a first load. A first controller is formed on a first substrate and controls power supply to the first load. A second controller is formed on a second substrate that is different from the first substrate, and instructs the first controller to perform an operation regarding power supply. The first controller and the second controller include a first switch and a circuit switch, respectively. The first switch and the circuit switch are provided on a current path of a current flowing via the first load. The second controller provides an instruction to switch the first switch on or off.

Abstract: In a power-supply control device, power supply to loads is controlled by driving circuits separately switching on or off FETs, respectively. In a state in which the connection destination of a fuse element is the FET, a microcomputer provides an instruction to switch the FET off. Then, the microcomputer determines whether or not a current is flowing through the FET. Upon determining that a current is flowing through the FET, the microcomputer switches the connection destination of the fuse element to the FETs, and provides an instruction to switch the FET on.

Abstract: Provided is a control device that stops the power supply when the first FET is short-circuited. In the control device, a boost circuit increases the voltage of one end of a resistor on the boost circuit side to a predetermined voltage that is higher than the source voltage of the first FET. An AND circuit instructs the discharge circuit to decrease the voltage at the other end of the resistor when the voltage at the other end of the resistor is less than a threshold voltage if the AND circuit instructs the boost circuit to increase the voltage at the one end of the resistor on the boost circuit side. The threshold voltage exceeds the voltage at the one end of the resistor if the voltage at the one end of the resistor on the boost circuit is the predetermined voltage and if the first FET is short-circuited.

Abstract: Provided is an onboard load control device and a computer program that can reliably detect and extinguish an arc discharge occurring between a pair of terminals of a connector. Arc discharges are caused in advance between terminals of a connector 2 that relays connection to onboard loads, a wireless detection unit receives electromagnetic waves generated due to the arc discharges, and detects frequency distributions of received intensities, and the detected frequency distributions are stored in a ROM in association with the respective onboard loads. Thereafter, frequency distributions that are acquired by the wireless detection unit chronologically are compared with the frequency distributions stored in the ROM, and the electric current flowing to the onboard load that corresponds to the matching frequency distributions is interrupted.

Abstract: Provided is an electric conduction system and a male terminal that prevent arc discharge by cutting off power supply prior to the occurrence of arc discharge. The male terminal is connected to the female terminal of the electric conduction apparatus, and power is supplied from the electric conduction apparatus. The male terminal includes a first resistance portion having a resistance value R1 on its rear-end side and a second resistance portion having a resistance value R2 on its front-end side. Accordingly, the resistance value of the power supply path varies depending on the amount the male terminal is inserted into the female terminal. By determining whether the electric current amount varies in accordance with a change in the resistance value of the power supply path, the electric conduction apparatus can cut off power supply prior to the male terminal coming off the female terminal, thus preventing an arc discharge.
