A display system that is configured for integration into a vehicle comprises a light source and an optical subsystem optically coupled to the light source. The optical subsystem includes a reflector and at least one semi-reflective optic, wherein the optical subsystem is configured to direct light rays to provide a plurality of virtual images that appear to a viewer concurrently at a respective plurality of different optical depths, by causing light of each of the virtual images to travel a different distance within the optical subsystem before exiting the optical subsystem on a path toward eyes of the viewer.

A position in a left-right direction of a display position of a facility figure representing a facility is set to a position overlapping with a virtual line parallel to a traveling lane as viewed from a driver (c). A position in an up-down direction of the display position is determined to be a position overlapping with a road surface on the front side, the position separated upward by H1 from a lower end of a display area of a heads-up display when a distance L from a current position CP to a position TP of a facility is a distance ThL (b1), to be a position separated by H4 (H4<h1) when the distance L is zero, and such that distances H2 and H3 separated upward from the lower end of the display area gradually change from the distance H1 to the distance H4 as the distance L decreases from the distance ThL to zero (b2 and b3). The distance H1 is set such that the facility figure is displayed below a point facing the facility on the road surface on the front side when the distance L is the distance ThL.

A virtual touch recognition apparatus and a method of correcting a recognition error of the virtual touch recognition apparatus utilize a user's eye position and an image display position or projection position of a head-up display (HUD). The virtual touch recognition apparatus includes a gesture recognizer detecting the eye position of a user, the head-up display projecting an image on the image display position in front of the user, and a controller correcting a recognition error of a virtual touch based on the eye position of the user and the image display position. The apparatus and method can minimize a virtual touch recognition error occurring depending on the user's eye position and the image display position of the HUD when gesture control technology using the virtual touch is applied to a vehicle.

A head-up display apparatus displays a virtual image suitably overlapped with actual scenery in accordance with a running condition of a vehicle. The head-up display apparatus acquires various kinds of vehicle information which can be detected by a vehicle and the display of the video image is based on the vehicle information. A mirror is configured to reflect the video image formed by the video image display to project onto the windshield. A mirror driver is configured to change an angle of the mirror and a display distance adjusting mechanism is configured to adjust a display distance of the virtual image with respect to the driver. The angle of the mirror is adjusted via the mirror driver based on the vehicle information such that the virtual image can be displayed with respect to the driver to be overlapped with the scenery.

A display control device configured to control a head-up display that projects an image onto an area ahead of a driver to display the image such that the image that is a virtual image is superimposed on an actual view. The display control device includes a controller. The controller is configured to execute control such that a highlighting image that highlights a specific object present ahead of a vehicle is displayed when a warning against the specific object is given to the driver. The specific object is detected based on traveling situation information regarding a traveling situation of the vehicle. The traveling situation information based on an output from a vehicular sensor including an on-board camera.

An object of the present invention is to provide a virtual image display optical system that is capable of substantially simultaneously displaying virtual images at a plurality of distances even with a simple configuration, and an image display device using the virtual image display optical system. A virtual image display optical system (30) according to the present invention is provided with: a display element (11); a projection optical system (15) that enlarges an image formed on the display element (11); a diffusing screen (16) that has a diffusing function, and is positioned on the light emission side of the projection optical system (15); and a virtual image forming optical system (17) that converts an image on the diffusing screen (16) into a virtual image, wherein the virtual image display optical system (30) is further provided with a positioning changing device (62) that changes a position of the diffusing screen (16).

A method for pairing a key fob with a control unit is provided. The key fob executes an ID authenticated key agreement protocol with a pairing device based on a key fob identification to authenticate one another and to generate a first encryption key. The pairing device encrypts a control unit identification using the first encryption key. The key fob receives the encrypted control unit identification transmitted from the pairing device. The key fob then executes an ID authenticated key agreement protocol with the control unit based on the control unit identification to authenticate one another and to generate a second encryption key. The key fob then receives an operational key transmitted from the control unit that is encrypted with the second encryption key.

A head-up display device is configured to project a display image in a vehicle onto a projection member that transmits an external real image to display the display image superimposed on the external real image for virtual image display visible to an occupant in the vehicle. A projection unit is configured to project a notification image as the display image for notifying the occupant of specific information onto the projection member. A display control unit is configured to control the projection unit to adjust a virtual image display state of the display image and to cut a virtual image display of specific pixels forming an inner portion inside an outer edge portion of the notification image.

A combiner is fastened to a base in a mobile object with a fastening member having a planar seat surface. The combiner displays a display light image as a virtual image visible to an occupant in the mobile object when the display light image is projected from a projection unit. The combiner includes a projection main body and a fastening protrusion. The projection main body is set with a projection region and has reflection surfaces displaying a virtual image by reflecting the display light image projected onto the projection region in a shape of a curved surface. The fastening protrusion has a planar fastening surface in surface contact with the seat surface. The fastening protrusion protrudes from the projection main body and is fastened to the base with the fastening member inserted into the fastening protrusion.
