A vehicular information display apparatus includes: a head-up display unit and a controller configured to change an arrangement of information in the vehicle information image that includes vehicle information image that includes a first region, and a second region. The first region includes a first image portion representing current vehicle speed information. The first image portion includes a vehicle speed value display representing a vehicle speed value, and a unit display representing a unit of the vehicle speed value. The controller is configured to set a position of the vehicle speed value display such that the position of the vehicle speed value is left-aligned in the first region, and configured to change a position of the unit display to a position directly below a rightmost numeral of the vehicle speed value display.

A vehicular three-dimensional head-up display includes a display device functioning as a light source; and a combiner for simultaneously reflecting light from the light source toward a driver's seat and transmitting light from the outside of a vehicle, and may include an optical configuration in which an image created by the light from the light source is displayed as a virtual image of a three-dimensional perspective laid to correspond to the ground in front of the vehicle.

A gradient change detection system for a moving body for detecting a change in a gradient of a traveling path, the gradient change detection system includes a posture detection unit that detects a posture change amount in a rotation direction about a left-right direction with respect to a traveling direction of a moving body, and a gradient change detector that detects a change in a gradient of the traveling path based on the posture change amount or a variation amount in predetermined unit time of the posture change amount.

An illumination unit includes a plurality of sets of illumination modules each having a light source placed at a conjugate position and a plurality of stages of condenser lenses that collect light from the light source toward a display device, a magnifying optical system being between the conjugate position and a viewing area. Each illumination module set includes an initial stage lens as a condenser lens closest to the light source and a final stage lens as a condenser lens farthest from the light source. In each illumination module set, assuming a composite focal point of a composite lens combined from all stages of condenser lenses, a gap between a principal plane of the initial stage lens and the light source is set to be equal to or less than a gap between the principal plane and the composite focal point.

An in-vehicle device includes: a drive assist unit configured to perform drive assist processing; a display unit configured to display an image in a display area with the image overlapped on a scene in a real space ahead of a vehicle; and a display control unit configured to control the display unit to display, in a normal state while the drive assist processing is performed, an image of a first marker at a vehicle-corresponding position as a position in the display area corresponding to a position where the vehicle is estimated to be positioned in the real space in a predetermined time. The first marker has a first color, the first marker has a first shape that has a smooth outline and fluctuates, and a display position of the first marker varies periodically from the vehicle-corresponding position.

A resin portion of an output shaft has a large diameter section, from which one end portion of a rod outwardly projects, and an intermediate diameter section, which extends from the large diameter section in an axial direction and is rotatably supported by a housing. A gear portion is formed in an outer peripheral surface of the large diameter section and is meshed with a final gear. A recess is recessed in the axial direction in the large diameter section and extends in the circumferential direction along an entire circumferential extent of the rod. The intermediate diameter section is continuously filled with resin in a region, which extends from an outer peripheral surface of the rod to an outer peripheral surface of the intermediate diameter section in the radial direction, along the entire circumferential extent of the rod.

The objective of the present invention is to provide a heads-up display device able to efficiently orient image light towards a viewer by means of a simple configuration. The heads-up display device is provided with: a projection unit that emits projection light depicting a display image; a first reflection unit and second reflection unit that reflect the projection light exiting the projection unit towards a transmissive screen; and the transmissive screen that outputs image light towards an observer by transmitting/scattering the projection light. By adjusting the angle of the light axis of the projection light entering the transmissive screen by rotating the first reflection unit and second reflection unit, the angle of the image light exiting the transmissive screen is adjusted.

A mobile machine includes an operator cabin, a user interface inside the operator cabin and one or more computing devices. The one or more computing devices are configured to identify an operator in the operator cabin, identify the mobile machine, and retrieve a user profile from a remote location, wherein the user profile is associated with the operator and indicates user interface settings specific to the operator and to the mobile machine. The one or more computing devices are further configured to enable the user interface according to the user profile.

The present invention suppresses movement of the line of sight of a user, reports the degree of potential risk, and contributes to the safe operation of a vehicle. A vicinity-monitoring unit detects a specific object in the vicinity of the vehicle. A display unit displays a mark image, which is visible to the user and is disposed continuously or intermittently on a trajectory, in a manner so as to surround the specific object at least partially. A control unit calculates the risk potential in relation to the specific object and alters, in accordance with the calculated risk potential, the line density of the mark image disposed on the trajectory.
