Description

Display device for vehicle Technical Field The present invention relates to a vehicle display device for displaying a desired display to a rider of a vehicle. Background Conventionally, for example, an in-vehicle display system described in patent document 1 is known. In this in-vehicle display system, control is performed such that when the vehicle is switched from the manual driving mode to the automatic driving mode, various information on the occupant (driver) is switched from the virtual image display to the real image display, and when the vehicle is switched from the automatic driving mode to the manual driving mode, various information on the occupant (driver) is switched from the real image display to the virtual image display. In addition, for example, a field control device described in patent document 2 is known. In this visual field control device, when the vehicle is switched to automatic driving, control is performed to move the seat upward or tilt forward. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2019-18804 Patent document 2 Japanese patent application laid-open No. 2019-48519 Disclosure of Invention Technical problem to be solved by the invention In recent years, in order to further improve the driver assistance function of the rider, a method of combining the display switching process of the real image and the virtual image described in patent document 1 and the seat switching process of the position or posture of the seat described in patent document 2 has been considered. However, if the time at which the position or posture of the seat is switched does not coincide with the time at which the display is switched, the display may be switched after a while after the switching of the seat is completed, or the switching of the seat may be completed after a while after the switching of the display is completed. In these cases, the time when the rider can feel that the driving mode is switched is dispersed in two, so there is a problem that the rider cannot be made to enhance the impression of the switching of the driving mode. The present invention has been made in view of the above-described problems, and an object thereof is to provide a display device for a vehicle that can enhance the impression of switching of driving modes for a rider.
