Abstract

L'invention concerne un procédé pour activer une soupape hydraulique à commande électrique, selon lequel un courant d'activation de la soupape hydraulique est modulé afin de réduire une hystérèse indésirable pendant le fonctionnement de ladite soupape hydraulique. L'invention se caractérise en ce qu'une courbe caractéristique courant-pression escomptée est comparée à une courbe caractéristique courant-pression mesurée afin d'identifier une hystérèse indésirable.
