The invention concerns a method for determining the running condition of a member rotating on a surface. The method includes an initial process of performing a spatial frequency analysis of the rotational speed of the member to identify at least one frequency window not including a harmonic of the revolution of the member wherein a law determining the running condition is established, and thereafter, an iterative process for determining the running condition including measuring the rotational speed V of the member; spatially sampling the speed with a constant spatial sampling period &Dgr;d; and analyzing the sampled signal in the frequency window identified so as to determine the running condition on the basis of the established law.
