Method and apparatus for evaluating vehicle tire condition by comparing tire operating parameters with present limits overtime
First Claim
1. Method of evaluating a vehicle tire condition comprising the steps of:
- providing a predetermined desired range for an operating condition of said tire, said range comprising at least one tire operating condition parameter;
continuously detecting instantaneous values of said at least one tire operating condition parameter;
comparing detected instantaneous values with said predetermined desired range to determine whether an instantaneous operating condition of said tire falls within said desired range; and
determining at least one of a frequency with which, and a proportion of overall tire operation during which, said instantaneous operating condition of said tire is outside said desired range.

Abstract
The invention provides a method and an apparatus for monitoring vehicle tires, in which a desired range for the operating condition of a tire, (represented by at least one tire operating condition variable) is predetermined. Instantaneous values of the at least one tire operating condition variable are recorded continuously and compared with the desired range in order to establish whether the instantaneous tire operating condition lies within or outside the desired range specified. The frequency with which, and/or the proportion of the overall operation during which the operating phases in which the instantaneous tire operating condition lies outside the desired range is determined throughout the entire operation of the tire.
