A vehicle wheel speed is calculated based on a vehicle wheel speed signal outputted from a vehicle wheel speed sensor and a change width w which is an amplitude of a time change component of the calculated vehicle wheel speed. When the calculated change width w is equal to or more than a reference value w0 it is judged that a quick tire deformation is currently generated and a driver of the vehicle is informed of the quick deformation by actuating a warning device.
La vitesse des roues d'un véhicule est calculée en fonction d'un signal de vitesse de ces roues émis par un capteur de vitesse des roues du véhicule et d'une largeur de changement w qui correspond à l'amplitude du composant de changement de temps de la vitesse calculée des roues du véhicule. Lorsque la largeur w est supérieure ou égale à une valeur de référence w¿0?, on estime qu'une déformation rapide des pneus est générée, et le conducteur du véhicule est informé de la déformation rapide par un dispositif d'avertissement.
