Abstract: A system power supply structure comprising: a power supply source; a plurality of systems each requiring a predetermined functional safety; and a plurality of relays inserted between the power supply source and the plurality of systems, wherein a system requiring the same functional safety among the plurality of systems is connected in parallel to the same relay among the plurality of relays.

Abstract: In the case where a predetermined condition related to a load is satisfied in a first state in which electric power is supplied from a second power supply source to the load via a second electric circuit and not supplied to the load via a third electric circuit when electric power cannot be supplied from a first power supply source to the load, a control unit controls a converting unit and a switching unit to establish a second state in which electric power is supplied from the second power supply source to the load via the second electric circuit and the third electric circuit.

Abstract: A vehicle door hinge structure includes: a door-side hinge fixed to a side door of a vehicle; and a body-side hinge rotatably connected to the door-side hinge, the body-side hinge being fixed to a pillar of the vehicle at a position inward, in a vehicle width direction, of a connection part with the door-side hinge and at a height equal to or lower than a lower end of the door-side hinge in a vehicle up-down direction.

Abstract: A vehicle door structure includes: a door hinge member mounted on a vehicle body; a door inner panel that constitutes a side door of an automobile; a door outer panel that is mounted on an outer side of the door inner panel in a vehicle width direction, and constitutes the side door of the automobile; and a door impact beam that is disposed between the door inner panel and the door outer panel, a first end side of the door impact beam being mounted on the door inner panel through a mounting member, a second end side of the door impact beam being rotatably mounted on the door hinge member.

Abstract: A step portion that is farther toward a vehicle width direction outside than a cabin inside vertical wall portion, is set on a door inner panel. A portion of the step portion is a first overlapping portion that is arranged in a position overlapping with an outside vertical wall portion of a center pillar in a vehicle side view. A portion of the outside vertical wall portion of the center pillar is a second overlapping portion that faces the first overlapping portion at a distance that is narrower than a distance between the step portion and the cabin inside vertical wall portion. A third overlapping portion that is connected to the first overlapping portion in a position overlapping with the second overlapping portion of the center pillar in the vehicle side view, is set on an end portion of a beltline reinforcement in a length direction thereof.
