Pit road display
First Claim
1. A pit road display for inclusion in a vehicle, comprising:
- a plurality of lights arranged to be successively illuminated, each of said lights having multiple colors;
setpoint establishing means for establishing lower and upper setpoints, and an intermediate setpoint indicative of an optimal engine speed; and
controller means for causing said plurality of lights to be successively illuminated at a first color when an engine speed is between the lower and intermediate setpoints, and to be successively illuminated at a second color when said engine speed is between the intermediate and upper setpoints, said illumination being carried out in a progressive manner, as follows;
said plurality of lights are dark when the engine speed is below the lower setpoint;
above the lower setpoint, a first of the plurality of lights is illuminated at a first color;
as the engine speed increases above the lower set point, neighboring ones of the plurality of lights are illuminated at the first color in a progressive sequence until the intermediate set point is reached, all of the lights are illuminated at the first color;
upon exceeding the intermediate set point, all of the lights are again dark, followed by illumination of the first of the plurality of lights at the second color and illumination of the neighboring ones of the plurality of lights in a progressive sequence until the upper set point is reached,wherein said upper setpoint represents a pit road speed limit and said intermediate set point represents an optimal pit road speed for a particular raceway.

Abstract
Instruments or gauges arranged to provide feedback detectable by the peripheral vision of a driver when vehicle operating parameters, such as engine speed, temperature, pressure, and voltage, are in a critical range, include one or more of the following types of instruments or gauges and/or features: (a) a tachometer that not only includes a primary numeric display, but also a secondary display made up of a plurality of discrete lights of different colors, the colors indicating whether the engine speed of a vehicle is within a relatively narrow range of engine speeds acceptable for the roadway leading from a race track to service areas, known as “pit road,” the high and low limits of the range being adjustable to meet pit road requirements at different tracks; (b) an instrument or gauge having a background that illuminates to indicate critical sensor readings; (c) an instrument or gauge having improved handling of sensor abnormalities to prevent false readings; (d) a non-linear analog gauge for a motor vehicle having a higher resolution in a particular range of interest, and a lower resolution outside that range; and (e) a boost pressure gauge that facilitates entry of gear information for use in traction control. The instruments or gauges of the invention are suitable for use in racing vehicles that meet standards established by NASCAR.
