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 predefined 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 a route taken successively in an actual course direction and belonging to a first segment portion including an initial point of said route 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 route segment, and connecting the first and second segment portions at a point of the route segment where a speed of the modeled vehicle on the first portion of said route segment does not exceed the speed of the modeled vehicle on the second portion of said route segment;
storing in memory a course time taken by the vehicle to cover the predefined route at least once;
comparing the course time to at least one reference time and producing a comparison result; and
optionally selecting a first 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 and including bends. The method includes the steps of 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 the 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.
