  • Patent number: 11932182
    Abstract: A control device includes: an in-vehicle communication unit capable of communicating with an on-vehicle control device; and a control unit configured to control the in-vehicle communication unit. The control unit monitors a power storage amount of an on-vehicle battery during traveling, and executes a charge control for causing the in-vehicle communication unit to transmit an instruction of power generation to an on-vehicle generator that supplies power to the on-vehicle battery, when the power storage amount is reduced to reach a threshold value. The threshold value corresponds to a power amount greater than a necessary power amount required for an update process of a control program in the on-vehicle control device.

  • Patent number: 11594464
    Abstract: A semiconductor device includes a semiconductor element, a base plate, and a plurality of contact materials. The base plate has a front surface holding the semiconductor element and a rear surface to which a cooling body to cool the semiconductor element is attachable. The plurality of contact materials are discretely arranged on the rear surface of the base plate. The plurality of contact materials are materials for bridging a gap on a heat dissipation path between the base plate and the cooling body. The plurality of contact materials each have a volume based on a bowed shape of the rear surface of the base plate. From among the plurality of contact materials, a contact material at a concave of the bowed shape has a greater volume than a contact material at a convex of the bowed shape.

  • Patent number: 10429508
    Abstract: A distance measuring device includes a first measurer, a second distance measurer, and circuitry. The first distance measurer measures a distance to a target object; and outputs first distance information indicating a measured distance when the distance measurement is performed under a condition that satisfies a distance measurement condition, but outputs the first distance information indicating a predetermined value when the distance measurement is performed under a condition that does not satisfy the distance measurement condition. The second distance measurer measures a distance to the target object and outputs second distance information indicating the measured distance. When the first distance information indicates the predetermined value and the second distance information satisfies a predetermined condition, the circuitry makes alteration such that the distance measurement condition is relaxed.
