1. A method for predicting, for a motor vehicle having at least one vehicle safety system and traveling on a first road segment, a future coefficient of friction of the vehicle on a second road segment, the method comprising:
obtaining operating parameters of the vehicle and at least one characteristic of the first road segment;
computing an indicator on the basis of the obtained operating parameters of the vehicle;
determining a frictional category of the vehicle according to the value of the computed indicator and of the at least one obtained characteristic of the road segment;
selecting a friction profile of the vehicle on the basis of the determined frictional category;
determining a coefficient of friction of the vehicle by applying the selected friction profile to at least one characteristic of the second road segment; and
using the coefficient of friction of the vehicle for configuration of the at least one vehicle safety system,
wherein at least one characteristic of the first and second road segments comprises, for a considered segment:
a surface characteristic of the roadway; and
a surface weather characteristic.
