Abstract: An orientation detection device obtains a detection information of a sensor that detects a displacement in the vertical direction occurring in the vehicle, computes a pitch angle of the vehicle on the basis of the detection information, obtains a gradient information indicating a gradient of a road on which the vehicle travels, and corrects a correlation between the detection information used in computation and the pitch angle on the basis of the gradient information.

Abstract: When the display is controlled by the head-up display used in the vehicle, prior to the display of the superimposed contents to be superimposed and displayed on the specific superimposed object existing in the foreground of the vehicle, the non-superimposed content which has substantially the same meaning as the superposed content to be superimposed and displayed on the foreground in a non-superimposed state on the superimposed object is superimposed and displayed on the foreground.

Abstract: 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.

Abstract: A display system applied to a vehicle includes a navigation device guiding a route to a destination and a display control device displaying multiple route guidance contents in superimposed manner on a road surface using a head-up display. When the navigation device determines that a first route guidance and a second route guidance included in route guidance information are successive guidance, (i) the navigation device concurrently displays images of the first route guidance and the second route guidance, and (ii) the display control device activates display of a first guidance content that performs the first route guidance, and then activates display of a second guidance content that performs the second route guidance after deactivating the display of the first guidance content.

Abstract: A vehicle display control device controls display performed by a head-up display for a vehicle. The head-up display is configured to project an image on a projection member to cause a virtual image to be displayed in superimposed relation on a front view of the vehicle. The vehicle display control device determines a host vehicle situation as a road structure of a road on which a host vehicle is running, and controls to limit or not to limit a superimposed display of the virtual image with respect to a target object on which the virtual image is to be displayed in superimposed relation according to the host vehicle situation determined.

Abstract: A display control device controls display of a virtual image which is superimposed on foreground of a vehicle by projection of a display light image from an optical unit to a projection area. The display control device sets a projection position of the display light image which is projected in the projection area on the basis of a relative position of a superimposition object on which the virtual image is superimposed, obtains a measurement information from one vehicle height sensor measuring a displacement in a vertical direction occurring in the vehicle, obtains a gradient information indicating a gradient of a road on which the vehicle travels on the basis of three-dimensional map data, and corrects the projection position of the display light image on the basis of the measurement information and the gradient information.

Abstract: A virtual image display device that displays a virtual image by projecting a display light image to a projection area of a vehicle, includes: a low-frequency information acquisition portion that acquires attitude change information of the vehicle at a low-frequency band; a high-frequency information acquisition portion that acquires attitude change information of the vehicle at a high-frequency band; an image renderer that renders image data of the display light image corrected to reduce misalignment attributed to the attitude change at the low-frequency band; a projection optical unit that includes a display surface to display an original image based on the image data, and projects light of the original image as the display light image; and a display controller that displaces the original image to reduce the misalignment of the virtual image attributed to the attitude change at the high-frequency band.
