Abstract
A vehicle state determination unit for determining a state of a vehicle, a display data output unit for outputting display data for displaying information indicating the state of the vehicle determined by the vehicle state determination unit, and an information displaying unit for displaying information to the outside of the vehicle in accordance with the display data output from the display data output unit are provided, in which the information displaying unit is configured to switch a display method of the information in accordance with an environment of the vehicle. By this, a degree of information transmission may be increased.
Claims11
An information display device, comprising:
- a processor;
- and
- a memory storing instructions which, when executed by the processor, causes the processor to perform processes of:
- determining a state of a vehicle;
- outputting display data for displaying information indicating the determined state of the vehicle;
- detecting a speed limit of a road on which the vehicle travels as an environment of the vehicle;
- and
- an information display to display information to an outside of the vehicle in accordance with the output display data,
- wherein the information display includes a light irradiation unit to display the information indicating the state of the vehicle on a projection surface by irradiating the projection surface outside the vehicle with light in accordance with the output display data and
- the light irradiation unit switches an angle of the light irradiated to the projection surface in accordance with the detected speed limit, wherein when the speed limit is high, the light irradiation unit changes the angle of light so that the projection surface is irradiated with light at a position farther from the vehicle than when the speed limit is low.
