Abstract

La présente invention se rapporte à un système de suspension de véhicule comprenant un actionneur (10) connecté entre la carrosserie (11) d'un véhicule et une roue et un ensemble roue et moyeu (18) de celui-ci. Une source de fluide sous pression (20) et une évacuation (24) destinée au fluide sont ménagées, ainsi qu'une soupape (22) pour commander l'écoulement du fluide vers l'actionneur (10) à partir de la source de fluide sous pression (20) et/ou de l'actionneur (10) vers l'évacuation du fluide (24). On utilise des éléments de détection (27, 28, 30, 31, 32, 33, 34, 35, 41) pour générer des signaux de paramètres variables, détectés, du véhicule. On utilise un système de commande pour le système de suspension du véhicule, qui possède des processeurs (25, 20) traitant les signaux générés par les éléments de détection (27, 28, 30, 31, 32, 33, 34, 35, 41). Les processeurs (25, 26) émettent un signal de commande à la soupape (22) et commandent ainsi l'actionneur (10). Les processeurs, dans des conditions normales de fonctionnement, utilisent un premier ensemble de constantes préprogrammées (par ex. gains de boucles d'asservissement, facteurs d'intégration, hauteurs réglables désirées) dans des algorithmes utilisés par les processeurs pour calculer le signal de commande ainsi émis. Les processeurs utilisent un ensemble différent de constantes préprogrammées dans les algorithmes pour une durée choisie suite à l'activation du système et/ou à des vitesses du véhicule faibles, et/ou à une basse pression du fluide alimenté par la source de fluide sous pression (20).
