  • Patent number: 11878731
    Abstract: A switch device includes a switch body, which is attached to and rotated integrally with an irregularly-shaped steering unit, and a lever unit, which is held pivotally about a switch body. The lever unit includes a lever shaft including a base, which extends in a direction intersecting the steering shaft, and an arm, which is formed integrally with the base and extends in a direction that differs from the direction in which the base extends. The lever unit also includes a lever head at the distal end of the lever shaft, and the lever head extends from the lever shaft in the width direction, which intersects an axial direction.

  • Patent number: 11875530
    Abstract: An image display system includes a display configured to be attached to the head of a user who is an occupant of a vehicle, to display a subject image to be superimposed on a field of vision of the user; a SLAM camera fixed to the display to capture a SLAM image of surroundings of the display; one or more light on-vehicle displays disposed within a vehicle cabin to emit light that serves as an AR marker; and an image controller configured to determine a display position of the subject image based on the SLAM image including the AR marker.

  • Patent number: 11815695
    Abstract: An image display system includes a wearable device including a display configured to display an image in a field of vision of a user and a first sensor configured to detect an absolute movement of the display, and a mobile terminal including a second sensor configured to detect an absolute movement of the vehicle. The image display system further includes an image controller including a computer installed in the mobile terminal to display a subject image on the display in an AR display mode. The image controller is configured to determine a display position of the subject image on the display based at least on the absolute movement of the display detected by the first sensor and the absolute movement of the vehicle detected by the second sensor.

  • Patent number: 11673597
    Abstract: A switch device includes a switch body, which is arranged at the back side of a steering unit, and a lever unit, which is attached to the switch body to allow for switching by a pivotal operation about a first axis, which extends in the axial direction of a steering shaft. The lever unit includes a lever shaft, which extends in a direction intersecting the first axis of the pivotal operation, a lever head, which is arranged at the distal end of the lever shaft and has a larger dimension than the diameter of the lever shaft, and a push operation unit, which allows for switching by a push operation. The push operation unit is arranged so that the operation direction of the push operation is directed toward the first axis.

  • Publication number: 20220396199
    Abstract: A lever operation device includes an operation lever which rotates integrally with a steering wheel of a vehicle and receives operations at least in upward and downward directions and around which a predetermined region is set so as to prevent the operation lever from contacting with a leg of a user seated in a driver's seat when the steering wheel is rotated to a maximum steering angle, and an operation portion that is arranged on the operation lever so as not to be located out of the region and includes plural operating positions each assigned an executable function.

  • Publication number: 20210280380
    Abstract: A switch device includes a switch body including a switch contact point, a lever unit pivoted about the switch body to switch the switch contact point between different states, and a guard arranged on a lever shaft of the lever unit and shaped to conceal the switch body at the proximal end of the lever shaft. The lever shaft includes a root portion, which is connected to the switch body, and a bent portion, which is bent and extended from the root portion. The guard is shaped so that the distance to a pivotal center of the lever unit is not constant.
