Abstract
A method for determining a road condition is carried out aboard a vehicle driving on the road and comprises the following steps: capturing the noise created by the friction between at least one tire and the road; analyzing the noise signal in the high frequency range to determine whether the road condition is dry or not; and, in case the road condition is not dry, analyzing the noise signal in the low frequency range to determine whether to road condition is wet or damp.
