  • Patent number: 12328375
    Abstract: Even in a case where conflicting requests are issued from apparatuses that belong to a domain, each of the apparatus are appropriately controlled. An operation support apparatus includes an reception unit which receives a plurality of requests from one or more apparatuses among a plurality of apparatuses that constitute a RAN, a TN and a CN and that operate according to an automated closed loop control method; and a control unit which (i) generates, from content of the plurality of requests, respective vectors each constituted by predetermined indices, and performs an operation on the vectors, and (ii) controls the plurality of apparatuses on the basis of a vector obtained by performing the operation.

  • Publication number: 20230003539
    Abstract: A navigation device includes an image display unit and a display control unit for controlling the display of the image display unit. The display control unit displays, in the image display unit, a map on a fixed scale in the form of a bird's eye view in which the front of the vehicle is overlooked, and displays a moving route by a guide line on the map until the distance to a guide point becomes a first display switching determination distance, when the distance to the guide point becomes the first display switching determination distance or shorter, increases a scale as the guide point is approached, and when the distance to the guide point becomes a second display switching determination distance or shorter, stops the increase of the scale, and displays, in an area where the guide line is displayed, a mark indicating a path at the guide point.

  • Patent number: 11125284
    Abstract: A brake dust cover includes an annular plate in which a cutout for avoidance of a brake caliper is provided in a first predetermined angle region, and a cover portion that overhangs to one side in an axial direction of the annular plate and covers an outer peripheral surface of a brake disc rotor is included at an outer periphery of a second predetermined angle region. The annular plate includes a small diameter region disposed in a third predetermined angle region other than the second predetermined angle region. In the annular plate, an outer diameter of the third predetermined angle region is smaller than an outer diameter of the second predetermined angle region. The annular plate does not include, in the small diameter region, a portion that overhangs to one side in the axial direction of the annular plate and covers the outer peripheral surface of the brake disc rotor.

  • Patent number: 10293690
    Abstract: A vehicle information projecting system includes: an image-capturing unit capturing an image of a road in front of a vehicle; a display mechanism projecting vehicle information onto a display region set as a portion of a windshield and displaying the vehicle information in the display region so that a virtual image of the vehicle information overlaps the actual landscape from the viewpoint of the vehicle driver; a rear vehicle information acquiring unit acquiring rear vehicle information representing the fact that a rear vehicle is present at the rear of the vehicle; lane change information acquiring units acquiring lane change information representing the fact that the vehicle is changing lanes from a traveling lane to a lane adjacent to the traveling lane; and a processing unit assessing the degree to which attention should be paid to the rear vehicle, based on the rear vehicle information and the lane change information.

  • Patent number: 9761145
    Abstract: Provided is a vehicle information projection system capable of accurately determining the approaching state of an obstacle and assisting the driver in driving. A vehicle information projection system that enables a user to view an image showing a lane information image together with the actual view outside a host vehicle, wherein a rearward-information acquisition unit detects the approaching of a rearward vehicle as well as the relative distance and the relative speed between the host vehicle and the rearward vehicle, and when the approaching of the rearward vehicle is detected by the rearward-information acquisition unit, a display controller performs display control so as to superpose and make visible a trajectory image that indicates the approaching of the rearward vehicle in a lane adjacent to that on which the host vehicle is traveling as acquired by a lane-information acquisition means.

  • Patent number: 4385529
    Abstract: A foot-operated parking brake lever assembly wherein a double-manual operation is required to effect release of the parking brake. The assembly is provided with a pawl having a first pawl section and a second pawl section. The first pawl section is pivotally mounted on a brake lever which is in turn pivotally mounted on a stationary support formed with a series of ratchet teeth. The first pawl section is formed with a finger for selectively engaging the ratchet teeth and thereby retaining the brake lever in brake setting positions thereof. The second pawl section is mounted on the first pawl section for limited rotational movement therewith.
