Patent attributes
A vehicle display device includes a display unit that displays at least an image relating to a driving state of a vehicle, a controller that generates image data of an image to be displayed on the display unit, and a temperature sensor that measures a temperature of the controller. The controller has a function of performing a first processing other than generating image data relating to the driving state. When the temperature of the controller is equal to or higher than a predetermined first value, the controller generates the image data relating to the driving state while reducing an amount of first processing performed by the controller.
