Abstract

A vehicle display control device includes a memory and a processor coupled to the memory. The processor is configured to: recognize a traffic regulation mark provided on a traveling path of a car, the traffic regulation mark indicating traffic regulation; specify a valid regulation range used as a valid range of regulation indicated by the traffic regulation mark based on the recognized traffic regulation mark; and control a display device mounted on the car to display regulations information on a display area, the regulations information including contents of regulation indicated by the recognized traffic regulation mark. The processor is configured to switch displaying the regulations information into another upon satisfying a predetermined condition in a case where the valid regulation range is not specified.

First claim

What is claimed is:

1 . A vehicle display control device, comprising:
a memory; and a processor coupled to the memory and configured to:
recognize a traffic regulation mark provided on a traveling path of a car, the traffic regulation mark indicating traffic regulation;
specify a valid regulation range used as a valid range of regulation indicated by the traffic regulation mark based on the recognized traffic regulation mark; and
control a display device mounted on the car to display regulations information on a display area, the regulations information including contents of regulation indicated by the recognized traffic regulation mark,
wherein the processor is configured to switch displaying the regulations information into another upon satisfying a predetermined condition in a case where the valid regulation range is not specified.

2 . The vehicle display control device according to claim 1 , wherein
the display area includes a plurality of display areas having different positions, and the processor is configured to switch one of the plurality of display areas used to display the regulations information into another upon satisfying the predetermined condition in the case where the valid regulation range is not specified.

3 . The vehicle display control device according to claim 1 , wherein the processor is configured to:
specify a residual amount of at least one of a remaining travel distance or a remaining travel time taken from a vehicle position of the car to an end position of the valid regulation range; control the display device to display the regulations information and residual amount information indicating the specified residual amount on the display area; and switch displaying the residual amount information into another upon satisfying the predetermined condition in the case where the valid regulation range is not specified.

4 . The vehicle display control device according to claim 2 , wherein the processor is configured to:
specify a residual amount of at least one of a remaining travel distance or a remaining travel time taken from a vehicle position of the car to an end position of the valid regulation range; control the display device to display the regulations information and residual amount information indicating the specified residual amount on the display area; and switch displaying the residual amount information into another upon satisfying the predetermined condition in the case where the valid regulation range is not specified.

5 . The vehicle display control device according to claim 1 , wherein
the processor is configured to specify the valid regulation range based on an image captured by an image sensor having an imaging range covering at least a predetermined range in front of the car, and the case where the valid regulation range is not specified is a case where the valid regulation range is not specified based on the image captured by the image sensor.

6 . The vehicle display control device according to claim 2 , wherein
the processor is configured to specify the valid regulation range based on an image captured by an image sensor having an imaging range covering at least a predetermined range in front of the car, and the case where the valid regulation range is not specified is a case where the valid regulation range is not specified based on the image captured by the image sensor.

7 . The vehicle display control device according to claim 3 , wherein
the processor is configured to specify the valid regulation range based on an image captured by an image sensor having an imaging range covering at least a predetermined range in front of the car, and the case where the valid regulation range is not specified is a case where the valid regulation range is not specified based on the image captured by the image sensor.

8 . The vehicle display control device according to claim 1 ,
wherein the predetermined condition means that a travel distance from a start position of the valid regulation range to a vehicle position of the car is equal to or more than a set value.

9 . The vehicle display control device according to claim 2 ,
wherein the predetermined condition means that a travel distance from a start position of the valid regulation range to a vehicle position of the car is equal to or more than a set value.

10 . The vehicle display control device according to claim 1 ,
wherein the predetermined condition means that a time taken from a start position of the valid regulation range to a vehicle position of the car is equal to or more than a set value.

11 . The vehicle display control device according to claim 2 ,
wherein the predetermined condition means that a time taken from a start position of the valid regulation range to a vehicle position of the car is equal to or more than a set value.

12 . The vehicle display control device according to claim 1 ,
wherein the predetermined condition means that a number of intersections or traffic signals existing between a start position of the valid regulation range and a vehicle position of the car is equal to or more than a set value.

13 . The vehicle display control device according to claim 2 ,
wherein the predetermined condition means that a number of intersections or traffic signals existing between a start position of the valid regulation range and a vehicle position of the car is equal to or more than a set value.

14 . The vehicle display control device according to claim 1 ,
wherein the predetermined condition means that the car passes a boundary between prefectures or municipalities.

15 . The vehicle display control device according to claim 2 ,
wherein the predetermined condition means that the car passes a boundary between prefectures or municipalities.

16 . The vehicle display control device according to claim 1 ,
wherein the predetermined condition means that selection from a user is accepted.

17 . The vehicle display control device according to claim 2 ,
wherein the predetermined condition means that selection from a user is accepted.

18 . The vehicle display control device according to claim 1 ,
wherein the predetermined condition means that a determination on a user recognition of the regulations information is performed based on a detection result by a line-of-sight sensor configured to detect a direction of a user's line of sight.

19 . The vehicle display control device according to claim 2 ,
wherein the predetermined condition means that a determination on a user recognition of the regulations information is performed based on a detection result by a line-of-sight sensor configured to detect a direction of a user's line of sight.

20 . A vehicle display control method, comprising:
recognizing a traffic regulation mark provided on a traveling path of a car, the traffic regulation mark indicating traffic regulation; specifying a valid regulation range used as a valid range of regulation indicated by the traffic regulation mark based on the traffic regulation mark recognized in the recognizing; and controlling a display device mounted on the car to display regulations information on a display area, the regulations information including contents of regulation indicated by the traffic regulation mark recognized in the recognizing, wherein the controlling includes switching displaying the regulations information into another upon satisfying a predetermined condition in a case where the valid regulation range is not specified in the speci
