Display device provided in vehicle and control method of display device
A display device included in a vehicle includes: a communication unit, a display; and a control unit. The communication unit can receive vehicle travel information. The processor can calculate a speed range based on the received vehicle driving information and control the display to display a graphic object representative of the calculated speed range on the display.
1. A display device included in a vehicle, the display device comprising:
a communication unit configured to receive vehicle driving information;
a display; and
a controller,
wherein the controller is configured to:
calculate a speed range based on the received vehicle driving information,
control the display to display a graphic object representative of the calculated speed range on the display, and
control the display to adjust at least one of a minimum value, a maximum value, or a unit interval of speeding corresponding to a graduation interval of a speedometer on the display, based on a difference between a first speed value and a second value, and a comparison of the calculated speed range against the first speed value and the second speed value.
2. The display device of claim 1 , wherein the controller is configured to calculate the speed range based on traffic signal information.
3. The display device of claim 2 , wherein the controller is configured to calculate, based on the traffic signal information and a predetermined area, a plurality of speed ranges, each of the plurality of speed ranges providing a speed range to keep the vehicle moving without stopping for entering the predetermined area or to stop the vehicle before entering the predetermined area.
4. The display device of claim 3 , wherein the controller is configured to control the display to display a plurality of graphic objects corresponding to the calculated plurality of speed ranges.
5. The display device of claim 4 , wherein the displayed plurality of graphic objects includes a graphic object with a predetermined color corresponding to a location of the vehicle.
6. The display device of claim 1 , wherein the controller is configured to control the display to decrease the maximum value of the speedometer to a predetermined value based on a comparison between the difference and the predetermined value.
7. The display device of claim 1 , wherein the controller is configured to control the display to reduce a unit interval of speed in the speedometer corresponding to the calculated speed range to a predetermined value based on a comparison between the difference and the predetermined value.
8. The display device of claim 1 , wherein the controller is configured to control the display to enlarge a part of the speedometer corresponding to the calculated speed range based on a comparison between the difference and a predetermined value.
9. The display device of claim 1 , wherein the controller is configured to control the communication unit to output a notification based a speed of the vehicle relative to the calculated speed range in a predetermined time.
10. The display device of claim 1 , wherein the controller is configured control the display terminate the displayed graphic object based on a speed of the vehicle relative to the calculated speed range in a predetermined time.
11. The display device of claim 1 , wherein the controller, based on a speed of the vehicle relative to the calculated speed range in a predetermined time, is configured to calculate a second speed range, and modify at least one of a size or a position of the graphic object according to the calculated second speed range.
12. The display device of claim 1 , wherein the controller is configured to calculate the speed range based on speed limit information on a driving road.
13. The display device of claim 1 , wherein the controller is configured to calculate the speed range based on driving mode information set in the vehicle.
14. The display device of claim 1 , wherein the controller is configured to calculate the speed range based on information associated with a predetermined safe distance from another vehicle.
15. The display device of claim 1 , wherein the controller is configured to calculate the speed range based on a vehicle's location relative to a predetermined area.
16. The display device of claim 1 , wherein the controller is configured to calculate the speed range based on status information of the vehicle.
17. A method for controlling a display device included in a vehicle, the method comprising:
receiving vehicle driving information from a communication unit;
calculating a speed range based on the received vehicle driving information;
displaying a graphic object representative of the calculated speed range on a display; and
controlling the display to adjust at least one of a minimum value, a maximum value, or a unit interval of speeding corresponding to a graduation interval of a speedometer on the display, based on a difference between a first speed value and a second value, and a comparison of the calculated speed range against the first speed value and the second speed value.
18. The method of claim 17 , wherein the calculating of the speed range includes calculating the speed range based on traffic signal information.
19. The method of claim 18 , further comprising calculating, based on the traffic signal information and a predetermined area, a plurality of speed ranges, each of the plurality of speed range providing a speed range to keep the vehicle moving without stopping for entering the predetermined area or to stop the vehicle before entering the predetermined area.
