AXIAL RELATIVE SPEED INDICATOR
First Claim
1. A method of indicating a speed of a vehicle relative to a speed limit, the method comprising:
- displaying a representation of the speed of the vehicle; and
displaying an indicator above the representation when the speed of the vehicle is greater than the speed limit to visually indicate a positive speed differential between the speed of the vehicle and the speed limit, or below the representation when the speed of the vehicle is less than the speed limit to visually indicate a negative speed differential between the speed of the vehicle and the speed limit.

Abstract
A speedometer displays a numeric representation of the speed of a vehicle, and further displays an indicator above the numeric representation to indicate the speed of the vehicle is above an established speed limit, or displays the indicator below the numeric representation to indicate the speed of the vehicle is below the established speed limit. The chromaticity of the indicator may be varied in relation to a magnitude of a speed differential between the speed of the vehicle and the speed limit to visually and intuitively indicate to an operator of the vehicle the magnitude of the speed differential.

12. A method of displaying a speed of a vehicle, the method comprising:
-
measuring the speed of the vehicle; determining the speed limit; calculating a speed differential between the speed of the vehicle and the speed limit, wherein the speed differential is a positive speed differential when the speed of the vehicle is greater than the speed limit and the speed differential is a negative speed differential when the speed of the vehicle is less than the speed limit; displaying a representation of the speed of the vehicle; and displaying an indicator above the representation when the speed differential is calculated to be a positive speed differential to visually indicate the speed of the vehicle is greater than the speed limit, or below the representation when the speed differential is calculated to be a negative speed differential to visually indicate the speed of the vehicle is less than the speed limit. - View Dependent Claims (13, 14)

15. A vehicle comprising:
a speedometer comprising; a vehicle speed display area configured for displaying a numerical representation of a speed; a positive speed differential display area vertically offset above said vehicle speed display area and configured for indicating a magnitude of a speed differential between the speed and a speed limit when the speed is greater than the speed limit; a negative speed differential display area vertically offset below said vehicle speed display area and configured for indicating a magnitude of the speed differential when the speed is less than the speed limit; and an equilibrium speed display area laterally offset from said vehicle speed display area and configured for indicating that the speed is equal to the speed limit. - View Dependent Claims (16, 17, 18, 19, 20)
