Abstract

Procédé d'alerte de risques de perte d'adhérence en virage sur route mouillée. On mesure l'adhérence instantanée des roues du véhicule et l'on compare la valeur mesurée à une valeur théorique maximale. On émet un signal d'avertissement du conducteur (8) si la valeur mesurée (10) se rapproche de la valeur théorique maximale.
