Abstract

On-board display control methods and systems are provided. In one implementation for displaying speedometer information and miscellaneous information on an instrument panel display, a nonuse region determination unit of an on-board display control device determines a nonuse speed region in a speedometer in accordance with a traveling status of a vehicle. A display control unit of the on-board display control device then exercises control such that an enlarged view of the miscellaneous information is displayed over the nonuse speed region when the nonuse region determination unit determines that there is the nonuse speech region.

Claims

1. An on-board display control device configured to display speedometer information and miscellaneous information on an instrument panel display (“

IP display”

) of a vehicle, the control device comprising;

a nonuse region determination unit configured to determine a nonuse speed region in a speedometer in accordance with a traveling status of a vehicle; and

a display control unit configured to exercise control such that an enlarged view of the miscellaneous information is displayed over the nonuse speed region when the nonuse region determination unit determines that there is the nonuse speed region in the speedometer.

2. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that a travel speed of the vehicle is equal to or less than a first predetermined speed V1 for a predetermined time period, that a region extending from a second predetermined speed V2 toward a higher speed in the speedometer is the nonuse speed region, where the first predetermined speed V1 is less than the second predetermined speed V2.

3. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the travel speed of the vehicle is equal to or greater than a first predetermined speed V1 for a predetermined time period, that a region extending from a second predetermined speed V2 toward a lower speed in the speedometer is the nonuse speed region, where the first predetermined speech V1 is greater than or equal to the second predetermined speed V2.

4. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the vehicle is traveling on a road with a speed limit equal to or lower than a predetermined speed V1, that a region extending from a second predetermined speed V2 toward a higher speed in the speedometer is the nonuse speed region, where the first predetermined speed V1 is less than or equal to the second predetermined speech V2.

5. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the vehicle is traveling on a road with a speed limit equal to or higher than a predetermined speed V1, that a region extending from a second predetermined speed V2 toward a lower speed in the speedometer is the nonuse speed region, where the first predetermined speed V1 is greater than or equal to the second predetermined speech V2.

6. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the vehicle is traveling on a road with a low speed limit, that a region extending from a predetermined speed toward a higher speed in the speedometer is the nonuse speed region.

7. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the vehicle is traveling on a freeway, that a region extending from a predetermined speed toward a lower speed in the speedometer is the nonuse speed region.

8. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the vehicle is traveling through traffic congestion, that a region extending from a predetermined speed toward a higher speed in the speedometer is the nonuse speed region.

9. The on-board display control device according to claim 1, wherein the nonuse region determination unit is configured to determine when a traveling status indicates that the vehicle is traveling backward, that a region extending from a predetermined speed toward a higher speed in the speedometer is the nonuse speed region.

10. The on-board display control device according to claim 1, wherein the display control unit is configured to exercise control such that, when the enlarged view of the miscellaneous information is displayed over the nonuse speed region, the speedometer information in the nonuse speed region is not displayed, and the speedometer information in a use speed region, which is outside the nonuse speed region, is displayed without a change to a prearranged state and a display mode.

11. The on-board display control device according to claim 1, wherein the display control unit is configured to exercise control such that, when the enlarged view of the miscellaneous information is displayed over the nonuse speed region, the speedometer information is displayed with changes to an upper limit value or a lower limit value, and is displayed with mutual intervals of a plurality of scales indicating speeds of the speedometer from prearranged states.

12. An on-board display control method for displaying speedometer information and miscellaneous information on an instrument panel display (“

IP display”

) of a vehicle, the method comprising, in sequence;

determining, by a nonuse region determination unit of an on-board display control device, a nonuse speed region in a speedometer in accordance with a traveling status of a vehicle; and

exercising control, by a display control unit of the on-board display control device, such that an enlarged view of the miscellaneous information is displayed over the nonuse speed region when the nonuse region determination unit determines that there is the nonuse speed region in the speedometer.
