Patent US 7,299,693

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.
