Title: (DE) VERFAHREN ZUM BERWACHEN EINES GEWICHTSSENSIERENDEN SYSTEMS FÜR KRAFTFAHRZEUG
(EN) METHOD FOR MONITORING A WEIGHT-SENSING SYSTEM FOR VEHICLES
(FR) SYSTEME ET PROCEDE DE DETECTION DE POIDS POUR VEHICULES MUNIS DE RESSORTS NON FLUIDIQUES
Abstract: front page image
(EN) A system and method of sensing a load on a vehicle (VHC) that includes a plurality of wheel-engaging members (AXL) is disclosed. The vehicle body (BDY) is supported on the plurality of wheel-engaging members and receives a cargo having a cargo weight. The method (200) includes providing a non-fluid spring (102, 104) having an unloaded length and a spring rate, the non-fluid springs are supported between the vehicle body and one of the wheel-engaging members and being deflected to a loaded length under the cargo weight of the cargo. The method continues with determining the loaded length of said non-fluid springs. The method also includes determining an approximate value of the cargo weight based at least partially upon said spring rate and said loaded length of said non-fluid spring.
(FR) Un système et un procédé de détection d'une charge sur un véhicule (VHC) comprenant une pluralité d'éléments d'engagement de roue (AXL) sont décrits. Le corps de véhicule (BDY) est supporté sur la pluralité d'éléments d'engagement de roue et reçoit une cargaison ayant un poids de cargaison. Le procédé (200) comporte la fourniture d'un ressort non fluidique (102, 104) ayant une longueur non chargée et une constante de rappel; les ressorts non fluidiques sont supportés entre le corps de véhicule et l'un des éléments d'engagement de roue et sont déviés à une longueur chargée sous le poids de cargaison de la cargaison. Le procédé se poursuit par la détermination de la longueur chargée desdits ressorts non fluidiques. Le procédé comporte également la détermination d'une valeur approximative du poids de cargaison à partir, au moins partiellement, de ladite constante de rappel et de ladite longueur chargée dudit ressort non fluidique.
