A head up display arrangement for a motor vehicle includes an image source providing images. Optics are then positioned to provide a reflection of the images such that the virtual images are perceived by a driver of the vehicle to be aligned with a road that is visible through a windshield of the vehicle. A force-detecting device detects a magnitude of a force exerted on the driver in a lateral direction from turning of the vehicle. An electronic processor adjusts, based on the magnitude of the force exerted on the driver, the virtual images and/or a position of the HUD Optics.

A vehicle display control device that controls to display a virtual image in a subject vehicle equipped with a head-up display that displays the virtual image in association with one front obstacle in outside scenery by projecting a display image on a projection member includes: an image storage device that stores, as the display image, a highlighting image for highlighting the front obstacle by a linear portion surrounding the front obstacle with a margin spaced apart from the front obstacle at a virtual image display position corresponding to an entire range less than an entire circumference other than a lower side of a periphery of the front obstacle; and a virtual image display control device that is provided by at least one processor and controls the virtual image display position and the virtual image display size.

A vehicle control device includes a traveling environment detection unit and an ECU as a controller. The ECU acquires traveling environment information indicating a traveling environment detected by the traveling environment detection unit. The ECU determines whether a vehicle is in an off-road traveling state where the vehicle travels on a bad road, based on the traveling environment information. When the vehicle is in the off-road traveling state, the ECU determines a traveling assist function that is capable of being applied when the vehicle travels on the bad road. Furthermore, the ECU alters a display manner such that the number of times of operation that is necessary to select the determined traveling assist function is smaller than when the vehicle is not in the off-road traveling state.

An information presentation method of presenting information to a driver of a first vehicle includes detecting an object located in front of the first vehicle. The method includes determining a risk of the objects, and outputting alert sound for alerting a first dangerous object when the first dangerous object is detected based on the risk. The first dangerous object corresponds to a first risk exceeding a predetermined level. The alert sound is presented to the driver as a sound image localized at a first position between the driver and the first dangerous object. The method includes changing a position of the sound image from the first position to a second position when the risk of the first dangerous object rises to a second risk. The second position is a position between the driver and the first dangerous object and closer to the driver than the first position.

Positional correction of an image occurring along with detection of a shift in vertical eye position unintended by the user is suppressed. First image correction corrects the position of an image displayed on a display device based on a vertical eye position and a lateral eye position. Second image correction corrects the position of the image displayed on the display device based on the vertical eye position and the lateral eye position. A second correction amount to the position of the image with respect to the amount of change in the vertical eye position is smaller than a first correction amount to the position of the image with respect to the amount of change in the vertical eye position during the first image correction. A processor switches between the first image correction and the second image correction in accordance with whether a prescribed condition is satisfied.

The present invention is to achieve a HUD display that is easy for an occupant to see while reducing a sense of discomfort by limiting obstruction of actual scene visibility. A display control device 700 includes a control unit 701 that controls a visibility level and a display state of a display object, wherein, in a case of performing a low-visibility process for setting the visibility level of the display object to a second visibility level lower than a first visibility level, the control unit performs a display object recognizability improvement process that includes at least one of the following: increasing the number of display elements 300, 302, 304 forming the display object compared to the case in which the first visibility level is set; and expanding the size of some or all of the display elements forming the display object compared to the case in which the first visibility level is set.
