An operating system includes a display device having at least two planar display regions, which are arranged one behind the other in a viewing direction of an operator and extend transversely to the viewing direction. The operating system can be used to control a plurality of apparatuses of a vehicle.

A projection control device includes a projection controller configured to control a projector of a head-up display device to project a display image such that a virtual image thereof is viewed in front of a viewer, a video data acquisition unit configured to acquire a captured video captured by an imager capable of capturing a video of the viewer, and a detection unit configured to detect a relative positional relationship of a pupil position of the viewer with respect to the virtual image, wherein the projection control unit is further configured to control the projector to project a reference position determination image on the viewer, and the detection unit is further configured to detect the relative positional relationship of the pupil position of the viewer with respect to the virtual image based on the captured video obtained by capturing the reference position determination video projected on the viewer.

A sound output and text display device for a vehicle, including: an output unit that, in a case in which sound to be output inside the vehicle has been decided, outputs the sound inside the vehicle; and a display unit that displays text corresponding to the sound on a windshield in accordance with a state of use of the vehicle.

A virtual image display device includes: a projection member that projects an image; and a projection optical system that forms a virtual image. A virtual image distance from an observer to the virtual image is not less than 2,500 mm. The projection optical system has one or more reflectors. A reflection surface of a final reflector that is included in one or more reflectors and finally reflects a light ray satisfies the following Conditional Relation 1:
10|z maxz min|30Conditional Relation 1 where z is an angle between a normal vector perpendicular to a tangent plane passing through an origin of the final reflector and a normal vector with respect to a tangent plane at any given point on the final reflector, z max is a maximum value of z, and z min is a minimum value of z. This arrangement provides a small-size virtual image display device.

A driving assistance apparatus for a vehicle includes an imaging device, an ECU, and a head-up display device. When a position in which a straight line connecting a predetermined position and a position of a particular object intersects with a position estimating plane that is a virtual plane position on the same plane as a virtual display area is defined as a particular object estimation position, an indicator is a motion indicator moving such that a tip end of the indicator approaches the estimation position along a virtual straight line set in the virtual display area with lapse of time, and the ECU is configured to perform control such that a position shift amount of the estimation position shifted from the virtual straight line in a width direction of a vehicle on the position estimating plane is equal to or less than a predetermined value in a predetermined pre-collision time.

A vehicle display device includes a housing to be mounted on a vehicle and having an opening, a display unit disposed inside the housing and configured to project a display image toward a reflection unit arranged in front of a driver seat through the opening, and a controller configured to cause the display unit to exhibit a range display that defines a maximum range for a display image, upon detection of information indicating a change in the viewpoint of a driver on the vehicle

A vehicle (10) for a driver (14) of the vehicle (10) and a display device (16) are provided. The display device (16) includes a projection surface (18) extending in the horizontal and vertical direction and a projector (20) that is configured so as to project a projection (24) onto the projection surface (18). The projection surface (18) is curved in the horizontal direction and surrounds the driver (14) in the horizontal direction by at least one hundred degrees. A method for displaying a projection (24) on a projection surface (18) for a driver (14) of a vehicle (10) is also provided. The method includes: d) determining a viewing direction and/or head orientation (26) of the driver (14) towards the projection surface (18); and f) projecting the projection (24) onto the projection surface (18) in the viewing direction and/or head orientation (26) of the driver (14).

A head up display superimposes a virtual image on an actual view in accordance with a traveling status of a vehicle. Vehicle information containing a lean of the vehicle in a pitch direction is detected by a first posture sensor, and a lean in a roll direction is detected by a second posture sensor. A controller controls display of video on the basis of the vehicle information. A mirror reflects the video to project the video to a windshield or combiner. A mirror driver changes an angle and/or a position of the mirror. At least one of a display state of the virtual image in a display area for the video or the angle and/or the position of the mirror via the mirror driver is adjusted by the controller on the basis of the lean in the pitch direction and/or the lean in the roll direction.

An HUD includes a projection unit that projects image light that is spatially modulated on the basis of image data onto a windshield, a sight line detection unit that detects a line of sight of a driver of a vehicle, and a system controller that acquires measurement data on shape of a region including a point that intersects the line of sight of the driver in a projectable range of the image light in the windshield, generates correction data for correcting distortion of an image based on the image light projected onto the region on the basis of the acquired measurement data and the direction of the line of sight of the driver, and corrects the image data using the generated correction data.

A surface panel is attached to an instrument panel so as to cover a display surface of a display unit disposed on the instrument panel of a vehicle. When the display unit is turned on, light L from the display unit is projected toward the driver's seat side via a thin hole formed in the surface panel.
