Abstract
A slip angle estimation includes a tire having one or more first and second strain sensor(s) affixed to opposite respective first and second tire sidewalls. The sensors measure a tire strain in their respective sidewalls and generate a sidewall strain signal indicative of strain present within the tire sidewalls. A slip angle estimation is made by estimating the difference in the signal slope of the sensors in the opposite sidewalls. A load estimation is further made for the tire from the inner and outer sidewall strain signals and the load estimation is used in the slip angle estimation.
