Test system for a tyre using an algorithm which compares the average slope of the variation of a parameter depending on another one

摘要

The system has a controller for determining two coefficients from slip (G) and adherence coefficient (mu ) of a tire, to model respective variation curves. The controller determines indicators of average gradients of the respective variation curves. The controller determines a target slip of the tire when a difference between the average gradients of the curves exceeds a predetermined gradient threshold.
