## Abstract

Provided is a display system for a vehicle. The display system includes a display device installed to be visually recognizable from the outside of a vehicle, and a control device configured to cause the display device to display state information of the vehicle. The control device receives a signal from a sensor that senses a distance from the vehicle to an object around the vehicle, and the control device changes display of the display device based on the distance.

## Claims

### Claim 1

A display system for a vehicle, comprising:
a display device installed to be visually recognizable from the outside of the vehicle; and
a control device configured to cause the display device to display state information of the vehicle,
wherein the vehicle is a vehicle that allows automatic driving or manual driving, and
the control device is connected to an automatic driving control device, the automatic driving control device providing information to the control device such that the control device causes the display device to display information indicating whether the vehicle is in a process of automatic driving or manual driving, and such information is represented to a pedestrian around the vehicle or the driver of another vehicle.

### Claim 2 (depends on 1)

The display system of claim 1, wherein the control device receives a signal from a sensor that senses a distance from the vehicle to an object around the vehicle, and
the control device changes display on the display device based on the distance.

### Claim 3 (depends on 1)

The display system of claim 1, wherein the display device is disposed to illuminate a road surface around the vehicle.

### Claim 4 (depends on 2)

The display system of claim 2, wherein the display device is disposed to illuminate a road surface around the vehicle.
