A head-up display apparatus for a vehicle may include: a housing defining an interior space, with an entrance formed on a side of the housing; a holder unit coupled at a side thereof to a combiner; a moving unit located in the interior space of the housing, rotatably coupled to the holder unit, and reciprocating in one direction to cause the combiner to be accommodated in the interior space of the housing or to be exposed to an outside through the entrance of the housing; a driving unit coupled to the moving unit to move the moving unit; and a tilting unit slidably coupled to the moving unit and coupled to the driving unit, the tilting unit being moved by the driving unit to cause the combiner to be tilted around an imaginary central axis transverse to the combiner.

A headup display device includes: a display having an emission surface that emits display light relating to predetermined information; a reflecting member that is disposed above the display and reflects the display light emitted from the display; a combiner part on which the display light reflected off the reflecting member is incident; a transmissive member that is disposed between the display and the reflecting member to cover the emission surface and transmits the display light emitted from the display toward the reflecting member; and a blocking member that is disposed above the transmissive member and blocks out light that is reflected off the transmissive member to be incident on the combiner part. A transmissive-member-side end of the blocking member is disposed to be movable from a first position where the light is blocked out to a second position closer to the transmissive member than the first position is.

A road vehicle comprising a vehicle dashboard, comprising in turn an exposed surface visible from within the passenger compartment; a content display device comprising a projection device which can be rolled up and unrolled, provided with a foldable screen; the projection device further comprising a support structure on which the rear main surface of the foldable screen is mounted; the support structure being rollable and unrollable around a winding axis, arranged within the vehicle dashboard; the vehicle dashboard further comprising a slit on the exposed surface and configured to be traversed by the foldable screen and by the support structure during the rolling up and/or unrolling of the projection device.

A road vehicle comprising: a vehicle dashboard, comprising in turn an exposed surface visible from the inside of the passenger compartment; a content display device comprising: a projection surface, which is arranged so as to substantially correspond to at least part of the exposed surface and configured to be visible to the passenger and/or to the driver while driving; at least one projection device, which is configured to project one or more contents onto the projection surface; wherein the projection surface follows at least a curvilinear line of the exposed surface.

A road vehicle comprising a vehicle dashboard, comprising in turn an exposed surface visible from the interior of the passenger compartment; a content display device; a first projection device, which is configured to project onto the first projection surface one or more contents; at least one first aesthetic surface, also configured so as to substantially correspond to said part of the exposed surface; a support element, pivotably mounted on the vehicle dashboard and on which at least the first projection surface and the first aesthetic surface are arranged around an axis of symmetry; a movement system configured to rotate of the support element between a first configuration and a second configuration.

Embodiments herein are directed to a transparent steering wheel system for a vehicle that includes a sensor system, a projection system, and an electronic control unit. The electronic control unit is configured to determine when a plurality of display data displayed on a display device behind a steering wheel is blocked by the steering wheel from a field of view of a driver, determine when a desirable notification is included in the plurality of display data, and when the desirable notification is included and the field of view of the desirable notification for the driver is blocked by the steering wheel, control the projection system to project the desirable notification onto the projection surface of the steering wheel that fully covers the steering wheel such that the steering wheel appears to be transparent when the desirable notification is displayed onto the projection surface.

A head-up display unit having a segmented cover includes a housing having an upper surface defining an aperture to an interior space and holding a combiner. The combiner is movable between a storage position within the housing and an operational position extending through the aperture. The segmented cover is movable between a closed position covering the aperture and an opened position uncovering the aperture. The segmented cover includes a plurality of flaps of rigid material, each having a generally rectangular elongated profile and arranged adjacent and parallel to one another. The segmented cover also includes a flexible connection between adjacent ones one of the flaps to allow the segmented cover to be rolled cylindrically into the opened position. The flexible connection includes flexible material overmolded on the flaps in one or more different configurations. A method of constructing the segmented cover for a head-up display unit is also provided.

One embodiment of an in-vehicle display device includes: a display unit that includes a transparent display part and a low-transmissivity display part, and that changes an area ratio of an area of the low-transmissivity display part to an area of the transparent display part; an image capturing unit that captures a space around the vehicle as an image; and a first display control unit configured to control the display unit such that the area ratio is increased when a predetermined condition is satisfied as compared to when the predetermined condition is not satisfied, and the image captured by the image capturing unit is displayed in the low-transmissivity display part after the area ratio has been increased.

An external vehicle notification information system may include a projector illuminating generated information using a light source, a lens transmitting the information, a reflector reflecting partial information of the information toward the lens, and a screen displaying the partial information transmitted from the lens.

The problem addressed by the present invention is to provide a head-up display device suitable for a curved windshield in a head-up display device provided with a combiner and a cover wherein the cover moves in the longitudinal direction of the vehicle. A front part of a guide rail extending in the longitudinal direction of the vehicle is curved downward. A cover, which moves along this guide rail, is moved by a drive link and a driven link. Because the curved guide rail is used, the dimension of a head-up display device in the longitudinal direction of the vehicle can be reduced, a large inclined surface can be provided on the upper front part of a housing, and the head-up display device can be placed close to a curved windshield.
