An onboard power supply device includes: a first system; a second system; a first switch; a second switch; an abnormality detecting unit; and a switch setting unit configured to set a normal state, if occurrence of the power supply fault is not detected, and set a fail-safe state in which the first switch is in an OFF state, if occurrence of the power supply fault is detected, and after the first switch is set to the fail-safe state, with respect to each of the systems, the abnormality detecting unit detects whether any system power supply fault has occurred, and after the first switch is set to the fail-safe state, if occurrence of a system power supply fault is not detected from both of the systems, the switch setting unit sets each of the switches to the normal state.

Onboard power supply device and onboard power supply control method

A power supply device includes: a first system connected to a first load; a second system connected to a second load; an inter-system switch configured to connect and disconnect the first system and the second system to and from each other; a controller configured to normally supply power of a first power supply to the first system and the second system and, in response to a fault of the first system being detected, turn off the inter-system switch to supply power of a second power supply to the second system; and a backup circuit which includes a discharge regulation unit configured to regulate discharging of the second power supply.

Power supply device and control method

A power supply control apparatus includes: a first system configured to supply electric power of a first power supply to a first load; a second system configured to supply electric power of a second power supply to a second load; an inter-system switch capable of connecting the first system to the second system and disconnecting the first system from the second system; a battery switch capable of connecting the second power supply to the second system and disconnecting the second power supply from the second system; a primary ground fault detection unit configured to cut off the inter-system switch and conduct the battery switch when a ground fault of the first system or the second system is detected by the primary ground fault detection unit; a secondary ground fault detection unit as defined herein; and a failure determination unit as defined herein.

Power supply control apparatus and power supply control method

There is provided a driving assistance device for supporting driving of a vehicle equipped with the driving assistance device such that if a driver starts a driving-related operation in the course of self-driving, switching from self-driving to manual driving is performed. An acquiring unit configured to acquire conditions of the driver. A determining unit configured to determine to invalidate switching to manual driving in the case where the conditions of the driver acquired when the operation was started represents a non-waking state, and determine to continue the invalidation for a predetermined period if the driver changes from the non-waking state to a waking state when the invalidation is being performed.

Driving assistance device and driving assistance method

An apparatus for melting and treating metal wastes including radioactive wastes, including a melting and treating vessel formed of the upper surface of a truck and split mold, wherein metal wastes are charged into the vessel in a closed system and melted by an electroslag melting method using a non-consumable electrode. This invention also provides a method which includes the steps of charging a slag melt starting agent and slag into the vessel in layers, and passing electricity through the non-consumable electrode to thereby heat the starting agent.
