Method for Selecting an Optimized Tire Configuration for a Road Vehicle Such as a Racing Car or Motorcycle
First Claim
1. A method for selecting, from a set of possible configurations, an optimized tire configuration for fitting a vehicle intended to run on a circuit following a predefined route, oriented in a single course direction and including bends, said method comprising the steps of:
- developing a physical model of the vehicle fitted with a first tire configuration;
dividing a digital image of the route into successive segments by connecting at points with associated vehicle speed limit values;
simulating, in iterations, the course by the modeled vehicle, of each route segment, firstly at maximum acceleration on portions of route taken successively in the actual course direction and belonging to a first segment portion including an initial point of said segment, and at maximum deceleration on route portions taken successively upstream from each other and belonging to a second segment portion including an end point of said segment, and connecting the first and second segment portions at a point of the segment where the speed of the modeled vehicle on the first portion of said segment does not exceed the speed of the modeled vehicle on the second portion of said segment;
storing in memory the course time taken by the vehicle to cover the route at least once;
comparing the course time to at least one reference time and producing a comparison result; and
optionally selecting the first configuration at the optimized configuration as a function of the comparison result.

Abstract
A method for selecting, from a set of possible configurations, an optimized tire configuration for fitting a vehicle intended to run on a circuit following a predefined route, oriented in a single course direction (SU) and including bends. This method comprises: developing a physical model of the vehicle fitted with a first tire configuration; simulating the route course by the modeled vehicle, optimizing the speed of said vehicle; storing in memory the course time taken by the vehicle to cover the route at least once; comparing the course time to at least one reference time and producing a comparison result; and optionally selecting the first configuration at the optimized configuration as a function of the comparison result.
