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 one of a first correction and a second correction when the second integer value is zero and the first integer value is positive, when the controller performs the first correction, the controller changes the first integer value from a positive value to zero so that both of the first integer value and the second integer value have a value of zero, and when the controller performs the second correction, the controller changes the second integer value from zero to a positive value so that both of the first integer value and the second integer value are positive,

display the first integer value and the second integer value on the digital display subsequent to performing one of the first correction and the second correction.

2. The vehicle display device according to claim 1, wherein the controller is configured to perform the first corrected when 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 be a value identical to the first integer value when the controller performs the second correction.

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 perform the second correction when the first integer value has a character size that is larger than a character size of the second integer, and

the controller is configured to correct the second integer value to be a value identical with the first integer value when the controller performs the second correction.
