The present invention relates to a top-contacted reflective sheet device, which is consisted of a base, a reflective sheet and a shaft group, and an angle adjustment module is further included. By the composition of above elements, a level and a flip angle of the reflective sheet is provided to be adjusted easily, and a top end of the reflective sheet could be fixed on a windshield of a vehicle to thereby remove shakes, so that a user may easily adjust the direction of the reflective sheet to obtain an optimal viewing angle, to thereby improve driving safety.

A combiner-positioning apparatus for a vehicular head-up display is provided. The combiner-positioning apparatus includes a drive unit for supplying a driving force, a combiner assembly including a combiner, the combiner being projected and exposed to an outside or retracted or hidden into a slot formed in a dashboard by the driving force, a guide unit for guiding sliding movement of the combiner assembly in a vertical direction, and a power transmitter for transmitting the driving force to the combiner assembly.

A steering apparatus of a smart mobility vehicle includes: a cockpit module disposed in front of a driver seat and a passenger seat within a vehicle; a steering wheel part connected to the cockpit module, and switchable between a position toward the driver seat and a position toward the passenger seat in a longitudinal direction of the cockpit module; and a locking part to fix the steering part according to a preset condition. The cockpit module includes a first flat section disposed in front of the driver seat and a second flat section disposed in front of the passenger seat; and a locking section curved upward to connect the first flat section and the second flat section.

A head-up display device that is to be mounted in a moving vehicle and enables an occupant in the moving vehicle to view a virtual image based on a reflected image of S-polarized light in a projection section, the head-up display device including: an image projector configured to apply projection light including S-polarized light; and the projection section on which the projection light is to be projected. The projection section includes laminated glass including a first glass plate defining a surface of the laminated glass on which the projection light is to be incident, a second glass plate defining a surface of the laminated glass from which the projection light is to be emitted, and a half-wave plate disposed between the first glass plate and the second glass plate. The first glass plate and the second glass plate each are formed from a glass composition containing silicon oxide, iron oxide, and an alkali metal oxide. At least one of the first glass plate or the second glass plate has a thickness of 0.3 mm to 3 mm, a total iron oxide content in terms of Fe.sub.2O.sub.3 in the glass composition of 0.2% by mass to 2.0% by mass, and a FeO content of 0.1% by mass to 0.5% by mass. The half-wave plate has visible light transmittivity and is configured to transmit light with an a* value of −2.5 to 4.5 and a b* value of −1.0 to 7.0 in a CIE color system. The reflected image is formed on a surface of the first glass plate which is to face an inside of the vehicle. The second glass plate is configured to emit from a surface thereof which is to face an outside of the vehicle the projection light converted to P-polarized light.

A vehicle display device includes a housing mounted in a vehicle and having a light-shielding outer wall that forms an accommodation space, a slit being formed in the outer wall, a three-dimensional display surface disposed in the accommodation space and on which a real image is formed by display light, a projector disposed in the housing and configured to project the display light onto the display surface, and a reflector disposed outside the housing and having a reflection surface configured to reflect the real image toward an eyepoint in the vehicle. The shape of the reflection surface is a recessed shape such that light rays of the real image intersect in an optical path extending from the display surface to the reflection surface through the slit.

A head-up display of the present disclosure projects a display image on a transparent reflecting member. The head-up display includes: a display device that displays the display image; and a projection optical system that projects the display image displayed on the display device. On an assumption that light reaching a center of a viewpoint region of the observer and corresponding to a center of the virtual image is reference light, the projection optical system includes a prism element that has an incident surface, a reflection surface, and an emitting surface different from the incident surface sequentially in an optical path from the display device. The emitting surface is inclined to the reference light. An inclination amount θ.sub.2 of the reference light emitted from the emitting surface with respect to the emitting surface lies in a range of 15°<|θ.sub.2|<45° in the optical path from the display device.

A vehicle head-up display that automatically repositions an eyebox by measuring a distance to a driver's face and a method of controlling the same are disclosed. A method of controlling a vehicle head-up display according to some embodiments includes performing a distance measurement by using a displacement sensor for measuring a distance to a face of a driver and performing a display position adjustment including adjusting a display position and a display angle of head-up display information based on a measured distance to the face of the driver. Positioning of driver's face and then automatically adjusting the display position and the display angle of the head-up display information adaptively to individual drivers can reduce the inconveniences of the manual setting of the head-up display in a vehicle frequented with car-sharing drivers.

A HUD apparatus is structured such that a first cover opens and closes a first opening, which is disposed on a path along which a combiner moves, and a second cover opens and closes a second opening, which is disposed in an optical path from a light-projecting portion of a light-emitting unit (second mirror) to the combiner. When the combiner is being moved from an accommodated position to a projecting position, the second cover retracts into a space between the combiner and the light-projecting portion while rotating forward, similarly to the first cover.

This display system includes: a projection device including a phase-modulation-type spatial light modulator element, a light source radiating light to a display part of the element, and a control circuit controlling the element and the light source; and projecting reflection light of the part of the element; and a reflecting mirror reflecting projection light of the device. The control circuit displays, on the part of the element, a first pattern and a second pattern associated with display information having different definition degrees. The reflecting mirror includes a first reflection region causing reflection light of a portion where the first pattern is displayed to enter, and reflecting the light toward a first display region, and a second reflection region causing reflection light of a portion where the second pattern is displayed to enter, and reflecting the light toward a second display region.

Provided are a projection-type display device, a safe-driving support method, and a non-transitory computer readable recording medium storing a safe-driving support program capable of securing safety while providing sufficient information to a driver even in a situation where a field of vision in a traveling direction of a motor vehicle is poor. An HUD includes a light modulation unit that modulates light emitted from a light source unit; a projection unit that projects the light modulated by the light modulation unit onto a combiner; a first image information generation unit that generates first image information and outputs the first image information to the light modulation unit; a second image information generation unit that generates second image information and outputs the second image information to a display device; and a control unit that controls operations of the first image information generation unit and the second image information generation unit.
