| 摘要 |
The present invention provides an apparatus adapted to engage a surface, such as a road or racetrack. The apparatus provides an output to an operator that is representative of the current tractive condition of the surface. The indication from the measuring device may be adapted to provide a quantifiable indication to a driver or crew related to recent changes in the tractive condition of the surface. The driver or crew may in turn configure aspects of a racing vehicle, driving methodology and performance expectations based on current and measurable surface conditions.
