Abstract

A vehicle display device includes a digital display configured to display together a first integer value representing travel speed in kilometers per unit time and a second integer value representing travel speed in miles per unit time, and a controller configured to perform, at a time the second integer value is zero and the first integer value is positive, one of a correction to set the first integer value to zero and a correction to set the second integer value to a positive value, and display the first integer value and the second integer value on the digital display.

Claims

1. A vehicle display device for use with a vehicle that includes a vehicle speed detector, the display device comprising:

a digital display configured to display together a first integer value representing travel speed in kilometers per unit time and a second integer value representing travel speed in miles per unit time; and

a controller configured to perform, at a time the second integer value is zero and the first integer value is positive, one of a correction to set the first integer value to zero and a correction to set the second integer value to a positive value, and display the first integer value and the second integer value on the digital display.

2. The vehicle display device according to claim 1, wherein

the controller is configured to correct the first integer value to zero at the time the second integer value is zero and the first integer value is positive.

3. The vehicle display device according to claim 1, wherein

the controller is configured to correct the second integer value to a value identical to the first integer value at the time the second integer value is zero and the first integer value is positive.

4. The vehicle display device according to claim 1, wherein

the controller is configured to cause the digital display to display one of the first integer value and the second integer value in a character size larger than a character size of an other of the first integer value and the second integer value.

5. The vehicle display device according to claim 4, wherein

the controller is configured to correct an integer value out of the first integer value and the second integer value, which is displayed in a smaller character size, to a value identical with an integer value displayed in a larger character size at the time the second integer value is zero and the first integer value is positive.

6. A vehicle display device for use with a vehicle that includes a vehicle speed detector, the display device comprising:

a digital display configured to display together a first speed value in kilometers per unit time and a second speed value in miles per unit time; and

a controller configured to display, at a time when one of the first speed value and the second speed value is equal to or larger than a maximum value of a speed range, the one of the first speed value and the second speed value in a display mode different from a display mode when the one of the first speed value and the second speed value is smaller than the maximum value.

7. The vehicle display device according to claim 6, wherein

the controller is configured to cause the digital display to display one of the first speed value and the second speed value in a character size larger than a character size of an other of the first speed value and the second speed value.

8. A vehicle display device for use with a vehicle that includes a vehicle speed detector, the display device comprising:

a digital display configured to display together a first speed value in kilometers per unit time and a second speed value in miles per unit time, the digital display configured to switch a main display target between the first speed value and the second speed value; and

a controller configured to switch the main display target on the digital display between the first speed value and the second speed value while maintaining a relative positional relation between a display position of the first speed value and a display position of the second speed value.

9. The vehicle display device according to claim 8, wherein

the controller is configured to cause the display to display one of the first speed value and the second speed value as a main display target and in a character size larger than a character size of an other of the first speed value and the second speed value.

10. The vehicle display device according to claim 8, wherein

the relative positional relation between the display position of the first speed value and the display position of the second speed value is the display position of the first speed value always being located above the display position of the second speed value.
