Method and apparatus for monitoring tire performance including slippage
First Claim
1. A method for controlling slippage of a vehicle, comprising:
- generating tire slippage information for at least one tire on the vehicle; and
processing the generated tire slippage information to determine a measure of vehicle slippage;
wherein the tire slippage information for the at least one tire is based upon a comparison of a generated reference frame of a surface opposite a tire contact area with a subsequently generated sample frame of the surface opposite the tire contact area to determine an amount and a direction of slippage between the tire contact area and the surface.

Abstract
A method and apparatus for assessing tire performance by generating accurate, timely tire-to-surface slippage information under any operational/environmental conditions and on any road and/or off-road surface without requiring instrumentation of the roadway. The approach is capable of storing generated tire-to-surface slippage information for later retrieval and analysis and/or capable of supporting dynamic, real-time collection and dissemination of generated data. One exemplary embodiment generates and disseminates tire-to-surface slippage information in real-time that is compatible with and may be formatted for use by any consumer vehicle control system as well as external test and analysis equipment.

5. A vehicle slippage control system, comprising:
-
at least one tire slippage monitoring module that generates tire slippage information; and a slippage monitoring control system that communicates with the at least one tire slippage monitoring module to receive the generated tire slippage information and that processes the received tire slippage information to determine a measure of vehicle slippage; wherein the at least one tire slippage monitoring module generates tire slippage information based upon a comparison of a generated reference frame of a surface opposite a tire contact area with a subsequently generated sample frame of the surface opposite the tire contact area to determine an amount and a direction of slippage between the tire contact area and the surface. - View Dependent Claims (6, 7, 8, 9, 10)
