A vehicle suspension control for a vehicle having each wheel (11) supported from the chassis of the vehicle trough a fluid operated extension element (13, 19), the control comprising a controller (27), a plurality of sensors (21, 23, 25, 27, 30, 32), a fluid flow controller (29), a first sensor (2 1) adapted to sense the relative position between the wheel (11) and the chassis and provide a first output to the controller, a second sensor (23) adapted to sense the pressure of the fluid in each extension element (13, 19) and provide a second output to the controller (27) adapted to receive the output from each of the sensors (21, 23) at each wheel, process the outputs and provide a wheel output to the fluid flow controller (29) for each wheel, the force applied by the extension elements (13, 19) between the chassis and wheels will maintain the attitude of the chassis substantially constant relative to a plane.

L'invention concerne une commande de suspension de véhicule. Chaque roue (11) est supportée par le châssis par l'intermédiaire d'un élément d'extension hydraulique (13, 19). Ladite commande comporte un contrôleur (27), une pluralité de capteurs (21, 23, 25, 27, 30, 32), un contrôleur de flux fluidique (29), un premier capteur (21) destiné à détecter la position relative de la roue (11) par rapport au châssis et émettre une première sortie vers le contrôleur, et un deuxième capteur (23) destiné à détecter la pression du fluide dans chaque élément d'extension (13, 19) et émettre une deuxième sortie vers le contrôleur (27) conçu pour recevoir la sortie de chaque capteur (21, 23) sur chaque roue, traiter les sorties et émettre une sortie de roue vers le contrôleur de flux fluidique (29) pour chaque roue. La force appliquée par les éléments d'extension (13, 19) entre le châssis et les roues maintient l'attitude du châssis essentiellement constante par rapport au plan.
