Patent number: 10414405Abstract: A method for determining a limit speed for driving, for a driver at a vehicle's steering wheel, includes a step of estimating a grip potential available at a given instant between a tire of the vehicle and a roadway on which a tire of the vehicle is running. The grip potential is estimated as a function of at least one of: a known influencing parameter, and a measured influencing parameter. The method also includes a step of determining a need for grip as a function of a driving situation of the vehicle and driving characteristics of the driver. The method further includes a step of determining a limit speed for driving as a function of the need for grip and the estimated grip potential. By virtue of the limit speed for driving, it is possible to prevent exceeding an estimate grip potential available.Type: GrantFiled: May 20, 2016Date of Patent: September 17, 2019Assignee: Compagnie Generale des Etablissements MichelinInventors: Marc Duvernier, Antoine Paturle, Benjamin Levrard, Jean-Louis Linda

Patent number: 10365248Abstract: In a method for determining conditions of a road and a tire, a measurement of a sound signal produced by the tire running on the road during a timeframe is recorded, and a spectral density of a power of the sound signal over a frequency interval is determined. The frequency interval is segmented into frequency bands, and each frequency band is associated with a representative data element representing a mean acoustic power measured in the frequency band. The representative data elements obtained from the measurement form variables of a vector associated with the measurement. A road condition and a tire condition are determined via a discriminant analysis of the representative data elements using a learning base. Each representative data element is obtained by finding a ratio between a mean acoustic power measured in a corresponding frequency band and a total acoustic power measured over an entirety of the frequency interval.Type: GrantFiled: December 15, 2014Date of Patent: July 30, 2019Assignee: Compagnie Generale des Establissements MichelinInventors: Antoine Paturle, Jérôme Antoni
