PIT ROAD DISPLAY
First Claim
1. A method of providing additional warnings to a driver of a vehicle when a parameter measured by a gauge becomes critical, said gauge having a faceplate, comprising the step of varying a background illumination of the entire faceplate to indicate that the parameter has become critical, whereby variation in background illumination provides notifications and alerts to the driver concerning said parameter through a peripheral vision of the driver.

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.
