It is aimed to provide a system for alerting a driver of a driver cabin of a motor vehicle, said system comprising: a plurality of light sources arranged in array to project a signal light against the windshield and/or side window, provided in the driver cabin along a horizontal contour of windshield and side windows, outside a line of sight of the driver, and arranged to show a mirror image of the light source in the windshield or side window, visible to the driver; a tracking controller, arranged to identify one or more objects to be tracked in the perimeter of the motor vehicle; a control system, coupled to the tracking controller for activating a number of light sources of the plurality of light sources, arranged to project a signal light indicative of said tracked object substantially centered along a virtual line of sight from the driver towards the identified object.

A vehicular display system includes a movable body displaceable between an erect position and a tilted position, a first moving body disposed on the vehicle upper side of the movable body in the erect position, a second moving body disposed on the vehicle lower side of the movable body in the erect position, a drive device that displaces the movable body between the erect position and the tilted position, a guide device that guides the second moving body along the displacement operation of the movable body between the erect position and the tilted position, a display device that allows a user to view vehicle interior display information as if the information were displayed in an information display area of the movable body, and an elastic member that applies an elastic force between the movable body and the drive device.

A window or other component may have glass layers and an interposed polymer layer in which a textured light-scattering layer with a diffuse reflectivity is embedded. The textured light-scattering layer may have a textured polymer carrier film coated with a partially reflective layer such as a metal layer. The polymer carrier film may be textured to cause gaps to form within the partially reflective layer. The gaps may be patterned to form ohmic heating current paths or other signal paths through the partially reflective layer. The partially reflective layer may also serve as an electrode in a light modulator such as a liquid crystal light modulator or other light modulator. Images may be projected onto the textured light-scattering layer. The light-scattering layer may also help extract light from a light guiding layer adjacent to the partially reflective layer.

An HUD 100 includes: a combiner support 15 that is provided in an operator cab 5 of a construction machine 1 and supports each of a plurality of combiners 12 having different transmittances to be attachable and detachable therein; a projection display section 50 that projects image light onto the combiner 12 supported by the combiner support 15 to display an image; and a system controller 60 that gives a notification of a combiner 12 to be recommended for work on the basis of a prediction value of a global horizontal irradiance during the work determined by a position of a working site where the work is being performed using the construction machine 1 and a period for which the work is performed.

A display control device for controlling a display position of a virtual image displayed and superimposed on a foreground in a vehicle (A), includes: an information acquisition unit for acquiring state information of the vehicle and extracting attitude change information and vibration information of the vehicle from the state information; a position correction unit for correcting a displacement of the display position of the virtual image with respect to the foreground caused by the attitude change of the vehicle, based on the attitude change information; a rough road determination unit for determining whether a road is a rough road, the road on which the vehicle is traveling or scheduled to travel, based on the vibration information; and a correction suppression unit for suppressing a correction control of the display position executed by the position correction unit and continuing to display the virtual image, based on a rough road determination.

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.

Provided are a projection type display device, a control method of a projection type display device, and a control program of a projection type display device, capable of being continuously used even in a case where a vehicle vibrates, and performing optimal display depending on the vibration. An HUD 100 includes a projection display section 50 that projects image light obtained by spatially modulating light emitted from a light source onto a combiner 12 to display a virtual image, a first vibration detector 61 that detects a first vibration of the combiner 12, a second vibration detector 62 that detects a second vibration of the projection display section 50, a third vibration detector 63 that detects a third vibration of the projection display section 50 with respect to the combiner 12 on the basis of the first vibration and the second vibration, and a display controller 64 that controls the image to be displayed by the projection display section 50. The display controller 64 changes a display format of content to be displayed by the projection display section 50 on the basis of the third vibration.

Provided are a projection type display device, a control method of a projection type display device, and a control program of a projection type display device, capable of fixing a position of a combiner to a desired position to enhance usability without imposing a burden on an operator of a working machine.
