  • Patent number: 11866053
    Abstract: A method for predicting, for a motor vehicle traveling on a first road segment, a future coefficient of friction of the vehicle on a second road segment. The method includes steps of obtaining operating parameters of the vehicle and at least one characteristic of the first road segment, of computing an indicator on the basis of the obtained operating parameters of the vehicle, of 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, of selecting a friction profile of the vehicle on the basis of the determined frictional category, and of determining a coefficient of friction of the vehicle by applying the selected profile to at least one characteristic of the second road segment. A device for implementing the prediction method is also disclosed.

  • Patent number: 11453400
    Abstract: A method for estimating a value representing the frictional behavior of a vehicle being driven on a road segment, including receiving operating parameters of a vehicle including at least, a driving wheel angular velocity, an angular velocity of a free wheel of the vehicle, and vehicle a dynamic characteristic; computing a first ratio between the driving wheel angular velocity and the angular velocity of a free wheel of the vehicle, which are acquired when the vehicle is moving substantially in a straight line at a velocity greater than or equal to a first preset threshold; determining, from the received operating parameters, a second ratio between the driving wheel radius and the free wheel radius; determining a slip rate from a product of the first and second determined ratios; and obtaining a value representing the vehicle's frictional behavior by normalizing the determined slip rate using at least the vehicle's dynamic characteristic.
