  • Publication number: 20200047806
    Abstract: A steering angle detection device is provided with a plurality of rotation angle sensors and a plurality of control units. The rotation angle sensors are capable of at least continuously calculating a rotation speed while an ignition switch of a vehicle is turned off, and are provided so as to correspond to steering angle calculation units which calculate steering angle based on the rotation speed and a rotation angle acquired from the rotation angle sensors and midpoint information related to the neutral position of a steering member. Power supplies are provided on a per-system basis. The rotation angle sensors or the control units are capable of holding the midpoint information while the ignition switch is turned off. If a power supply abnormality resulting in power supply failure occurs in some of the systems, the control unit of the abnormal system acquires the midpoint information and the rotation speed from the control unit of a normal system when the ignition switch is turned on.

    Abstract: A planar light source emits planar light by power supplied from a mounting member. The planar light source includes an engaging part, a planar-light-emitting panel having a light-emitting surface, and a connecting unit disposed between the engaging part and the planar-light-emitting panel. The engaging part forms a portion of a power supply path for supplying power from the mounting member to the planar-light-emitting panel. The planar-light-emitting panel includes a planar-light-emitting tile and a translucent plate, where one main surface of the planar-light-emitting tile includes a light-emitting region. The planar-light-emitting panel emits, in a lighting state, the planar light from the light-emitting region of the planar-light-emitting tile through the translucent plate. An output of the planar light from the planar light source is adjusted by pressing the light-emitting surface.
