Abstract

A display control method for controlling displays of a first display device and a second display device included in a vehicle is provided. The display control method includes displaying, on the first display device, a transparent screen at a position where a driver is capable of viewing an outside of the vehicle through a windshield; locating a screen of the second display device at a position different from the screen of the first display device; and in a case that a line-of-sight position of the driver detected by a line-of-sight detection device included in the vehicle does not match the position of the screen of the second display device, controlling the display of the screen of the second display device more than the display of the screen of the first display device.

Claims (51)

1 . A display control method for controlling display devices in a vehicle, the display control method comprising:

displaying first information on a first screen of a first display device of the display devices while the vehicle is traveling, the first screen being transparent and located at a first position in the vehicle, a driver of the vehicle being capable of viewing an outside of the vehicle through the first screen and a windshield;

displaying second information on a second screen of a second display device of the display devices when a line-of-sight position of the driver detected by a line-of-sight detection device is on the second screen of the second display device while the vehicle is travelling, the second screen being located at a second position in the vehicle, the second position being different from the first position of the first screen of the first display device;

controlling the second display device to not display the second information when the line-of-sight position of the driver detected by the line-of-sight detection device is not on the second screen of the second display device while the vehicle is travelling; and

displaying the second information on the second screen of the second display device regardless of whether the line-of-sight position of the driver detected by the line-of-sight detection device is on the second screen while the vehicle is stopped.

2 . The display control method according to claim 1 , wherein

the second position of the second screen of the second display device is located below the first position of the first screen of the first display device in the vehicle.

3 . The display control method according to claim 1 , wherein

the controlling of the second display device to not display the second information includes not displaying the second screen of the second display device.

4 . The display control method according to claim 1 , wherein

the controlling of the second display device to not display the second information includes not displaying the second information on the second screen of the second display device.

5 . The display control method according to claim 1 , wherein

speed information of the vehicle is configured to be displayed on the first screen of the first display device as the first information, and

the speed information is not configured to be displayed on the second screen of the second display device as the second information.

6 . The display control method according to claim 1 , further comprising:

displaying third information on a third screen of a third display device of the display devices when the line-of-sight position of the driver detected by the line-of-sight detection device is on the third screen of the third display device while the vehicle is travelling, the third screen being located at a third position farther than the second position of the second screen with respect to a seat of the driver in the vehicle, the third position being different from the first position of the first screen of the first display device; and

controlling the third display device to not display the third information when the line-of-sight position of the driver detected by the line-of-sight detection device is not on the third screen of the third display device while the vehicle is travelling.

7 . The display control method according to claim 6 , wherein

avoiding danger information for avoiding danger of driving is configured to be displayed on the first screen of the first display device as the first information,

safety traveling information related to safe traveling of the vehicle is configured to be displayed on the second screen of the second display device as the second information, and

assisting traveling information for assisting traveling of the vehicle is configured to be displayed on the third screen of the third display device as the third information.

8 . A vehicle configured to travel in a direction, the vehicle comprising:

a body;

a first wheel coupled with the body and aligned in the direction;

a second wheel coupled with the body and aligned in the direction;

a third wheel coupled with the body and aligned in the direction;

a fourth wheel coupled with the body and aligned in the direction;

a first display device including a first screen, the first screen being transparent and located at a first position in the vehicle, a driver of the vehicle being capable of viewing an outside of the vehicle through the first screen and a windshield;

a second display device including a second screen, the second screen being located at a second position in the vehicle, the second position being different from the first position of the first screen of the first display device; and

a line-of-sight detection device configured to detect a line-of-sight position of the driver of the vehicle, wherein

the vehicle displays first information on the first screen of the first display device while the vehicle is traveling,

the vehicle displays second information on the second screen of the second display device when the line-of-sight position of the driver detected by the line-of-sight detection device is on the second screen of the second display device while the vehicle is travelling,

the vehicle controls the second display device to not display the second information when the line-of-sight position of the driver detected by the line-of-sight detection device is not on the second screen of the second display device while the vehicle is travelling, and

the vehicle displays the second information on the second screen of the second display device regardless of whether the line-of-sight position of the driver detected by the line-of-sight detection device is on the second screen while the vehicle is stopped.

9 . The vehicle according to claim 8 , wherein

the second position of the second screen of the second display device is located below the first position of the first screen of the first display device in the vehicle.

10 . The vehicle according to claim 8 , wherein

the vehicle controls the second display device to not display the second screen of the second display device when the line-of-sight position of the driver is not on the second screen while the vehicle is travelling.

11 . The vehicle according to claim 8 , wherein
