  • Patent number: 11512773
    Abstract: A selector unit includes a panel, and a dial member that protrudes in a first direction from an opening of the panel. A surface of the panel includes a concave surface having a depth that increases toward the opening. The dial member has an operation portion gripped by a user, and a base shaft portion that extends from the operation portion through the opening of the panel. At least a part of an outer circumferential surface of the base shaft portion is an inclined surface that is inclined radially outward as being away from the panel, and the inclined surface is opposed to the surface of the panel in the first direction. The distance from the surface of the panel to the inclined surface of the dial member in the first direction continuously increases, as a radial distance from the opening to the inclined surface increases.

  • Publication number: 20220345324
    Abstract: A network system includes a higher-level device, a first intermediate device connected to the higher-level device, and a second intermediate device connected to the higher-level device. The first intermediate device is configured to control supply of an electric power to a first lower-level device via a first device being able to be controlled to interrupt. The second intermediate device is configured to control supply of an electric power to a second lower-level device via a second device being able to be controlled to interrupt, the second lower-level device being a redundant component for the first lower-level device.

  • Publication number: 20220120345
    Abstract: A selector unit includes a protruding portion and a dial member. The dial member is configured to be displaced between an initial position and a depressed position along an axial direction of the protruding portion, and to be rotationally operable in a circumferential direction when depressed to the depressed position. An offset angle at a rearward side when the dial member is at the initial position is greater than the offset angle at a forward side when the dial member is at the depressed position. The offset angle means an angle between an extended line obtained by extending an upper face of the protruding portion outwards in a radial direction and a tangential line in contact with both the upper face of the protruding portion and an upper face of the dial member, in a section including a rotation axis of the dial member.

  • Publication number: 20220121269
    Abstract: An in-vehicle control device includes a processor configured to: control a device of a first type, which has a function of switching an operation mode between a normal mode and a mode in which power consumption is limited compared to the normal mode in accordance with an instruction via communication and a device of a second type, which does not have the function; specify a limited device that is a device of which power consumption is to be limited, based on information acquired from outside; transmit to the limited device via a communication line an instruction to shift the operation mode to the mode in which power consumption is limited compared to the normal mode, when the limited device is the device of the first type; and stop power supply to the limited device when the limited device is the device of the second type.
