Abstract
The invention provides a process for the advance recognition of the hydroplaning of a vehicle tire on a wet road, in which the rotational speed of the wheel carrying the tire is sensed by a rotational speed sensor and the frequency spectrum of the rotational wheel speed is evaluated. According to the invention, in the frequency range above 20 Hz, the natural resonance behavior of the rotational tire vibrations is evaluated continuously, and a conclusion on hydroplaning of the tire is drawn from detuning of the rotatory natural frequencies.
