A head-up display device that is configured to allow a driver to intuitively recognize a plurality of objects sequentially along a travel route of a vehicle while projecting a video onto an image forming plane that has a length in the vertical direction shorter than a length in the horizontal direction. An optical processor of the head-up display device obtains from a controller a first image signal based on the nearest road sign information and a second image signal based on the following road sign information along the travel route. The optical processor causes line segment objects as well as information objects generated from the first image signal and the second image signal, respectively, to be displayed on an image forming plane.

A display device includes: an acquisition unit configured to acquire information on a use status of a battery that stores electric power for traveling of a vehicle; a display unit configured to display an image; and a display control unit configured to cause the display unit to display an image in which a state of the battery is represented by an anthropomorphic character based on an acquisition result of the acquisition unit.

A display device is mounted on a vehicle. The display device comprises a display unit and a control unit A virtual screen is a two-dimensional plane at a predetermined distance away from an origin of a XYZ coordinate system along a Y coordinate axis, and is approximately parallel to an XZ plane defined by an X coordinate axis and a Z coordinate axis. The control unit is configured to calculate coordinates of a second point obtained as a result of projecting a first point in the XYZ coordinate system onto the virtual screen, convert the calculated coordinates of the second point into coordinates according to a display mode of the display unit, and cause the display unit to display an image corresponding to the second point at the converted coordinates.

Methods and systems are provided for adjusting parameters using a vehicle touch screen. In one embodiment, a method includes determining an initial touch position of an external touch operation when the external touch operation is detected. A movement trajectory and final disengagement position of the external touch operation may then be detected. The movement trajectory need not be limited to an area covered by a parameter adjustment control. The parameter adjustment control may then be adjusted to a final parameter value according to the initial touch position, the final disengagement position, and the movement trajectory.

Provided is an operating state display method in an electric vehicle in which the drive electric power is supplied from a battery to a travel motor. The operating state display method includes an eco-level setting step of setting an eco-level with respect to an operating state of the electric vehicle based on a vehicle speed of the electric vehicle and an output of the travel motor, and a display step of displaying in a vehicle cabin an eco-level gauge configured to expand or contract according to the eco-level.

A display device includes a display configured to display a video, a concave mirror configured to reflect a video display light of the video displayed on the display toward a reflection part that is formed in a curved shape and that faces a viewer, and a housing in which the display and the concave mirror are assembled, wherein an angle of the concave mirror with respect to the housing is adjustable by rotating the concave mirror on a reference plane of the housing in accordance with a relative positional relationship among the housing, the reflection part, and the viewer.

Content on a display of a vehicle is controlled based on a degree of automation of a driving state of the vehicle and at least one further state variable of the vehicle or of a passenger.

A seat control device includes a memory and a processor coupled to the memory. The processor is configured to, based on a selection by an occupant of a vehicle, select a video display area for displaying a video from among a plurality of video display areas provided at the vehicle, determine an adjustment amount corresponding to the determined video display area for a vehicle seat provided in the vehicle, and, via a modulation section, modulate a position and posture of the vehicle seat based on the determined adjustment amount of the vehicle seat.

A vehicle includes an image capturing device configured to capture an image in a vehicle traveling direction, a display device, and a controller configured to carry out an analysis of the image captured by the image capturing device and display an indicator based on the analysis on the display device. The controller is configured to display a first object that approaches a host vehicle on the display device in a mode different from a mode for a second object that does not approach the host vehicle within the image captured by the image capturing device.

A vehicular display control device that is configured to: display, at a display, an image of a switch that causes a transition from a first state to a second state in response to being pressed a first time and does not cause a return from the second state to the first state in response to being pressed a second time or more than a second time; and display, at the display, a text string indicating that the transition to the second state is complete in response to the switch having been pressed once in a state in which the image is displayed.
