Assignee: CONTINENTAL AUTOMOTIVE GMBH
Field: Transport (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 3:
4. The method as claimed in claim 1, wherein the friction profile is selected from a set of frictional profiles, with the set of frictional profiles being determined according to the following:
collecting, for a plurality of collection instants, training vehicle data, with a training vehicle data item comprising at least, for a given instant:
a road surface characteristic;
a surface weather characteristic; and
a coefficient of friction estimated by the vehicle;

determining a plurality of frictional categories of vehicles by unsupervised classification of the collected data, so that a particular frictional category comprises vehicles with a coefficient of friction within the same range of values for a given surface characteristic and weather characteristic; and
determining at least one vehicle friction profile, with a friction profile being defined by a set of frictional categories to which a particular vehicle is assigned.
