Abstract

A display system equipped to a vehicle includes a display screen, a notification section, a determination section, and a display control section. The display screen displays information for a vehicle occupant. The notification section preliminarily notifies the vehicle occupant of an information update to be performed on the display screen. The determination section determines whether the vehicle occupant pays attention to the display screen after the notification section notifies of the information update. The display control section performs the information update in order to display new information on the display screen when the determination section determines that the vehicle occupant pays attention to the display screen.

Claims

1. A display system equipped to a vehicle comprising:

a display screen displaying an information for a vehicle occupant;

a notification section preliminarily notifying the vehicle occupant of an information update to be performed on the display screen;

a determination section determining whether the vehicle occupant pays attention to the display screen after the notification section notifies of the information update; and

a display control section performing the information update in order to display a new information on the display screen when the determination section determines that the vehicle occupant pays attention to the display screen.

2. The display system according to claim 1,

wherein the determination section determines whether the vehicle occupant pays attention to the display screen by monitoring at least one of a line of sight or a face orientation of the vehicle occupant.

3. The display system according to claim 1,

wherein the determination section determines that the vehicle occupant pays attention to the display screen when a predetermined operation is performed by the vehicle occupant.

4. The display system according to claim 1,

wherein the notification section continues to notify the vehicle occupant of the information update to be performed on the display screen until the determination section determines that the vehicle occupant pays attention to the display screen.

9. The display system according to claim 1, further comprising:

at least one of a light emitting unit that emits light, a speaker that outputs a sound, or a vibration apparatus that generates a vibration,

wherein the notification section notifies the vehicle occupant of the information update by at least one of the light emitted by the light emitting unit, the sound output by the speaker, or the vibration generated by the vibration apparatus.

5. A display system equipped to a vehicle comprising:

a display screen displaying an information for a vehicle occupant;

a display control section performing an information update in order to display a new information on the display screen;

a notification section preliminarily notifying the vehicle occupant of the information update to be performed on the display screen by the display control section; and

a setting section setting a standby time for the new information, the standby time varying according to a type of the new information,

wherein, when the standby time set for the new information elapses after the notification section starts notifying of the information update, the display control section performs the information update and displays the new information on the display screen.

6. The display system according to claim 5,

wherein the notification section notifies the vehicle occupant of the information update to be performed on the display screen in a notification mode, which varies according to the type of the new information.

7. The display system according to claim 5,

wherein, when the new information has an urgency degree equal to or higher than predetermined criteria, the setting section sets a first standby time for the new information,

wherein, when the new information has an urgency degree lower than the predetermined criteria, the setting section sets a second standby time for the new information, and

wherein the first standby time is shorter than the second standby time.

8. The display system according to claim 5,

wherein, when the new information is a requested information that is requested by the vehicle occupant, the setting section sets a first standby time for the new information,

wherein, when the new information is an information other than the requested information, the setting section sets a second standby time for the new information, and

wherein the first standby time is shorter than the second standby time.
