Title (EN) CONTROL OF A HYDRAULIC TRANSMISSION AS A FUNCTION OF THE AGEING OF THE TRANSMISSION FLUID
(FR) PILOTAGE D'UNE TRANSMISSION HYDRAULIQUE EN FONCTION DU VIEILLISSEMENT DU FLUIDE DE TRANSMISSION
Abstract:
(EN) The invention relates to a system (2) for controlling a disengageable hydraulic transmission (1) for a vehicle, involving the circulation and the pressurisation of a transmission fluid, said system (2) comprising: - means (21) for collecting information relative to the operation of the hydraulic transmission (1) since the last time the transmission was serviced, - means (22) for estimating an ageing state of the transmission fluid based on the information collected, and - means (23) for controlling the disengageable hydraulic transmission (1) as a function of the estimated ageing state.
(FR) L'invention porte sur un système de pilotage (2) d'une transmission hydraulique (1) débrayable pour véhicule, impliquant la circulation et la mise sous pression d'un fluide de transmission, ledit système (2) comprenant: - des moyens (21) pour recueillir une information relative au fonctionnement de la transmission hydraulique (1) depuis une dernière maintenance de la transmission, - des moyens (22) pour estimer un état de vieillissement du fluide de transmission à partir de l'information recueillie, et - des moyens de pilotage (23) de la transmission hydraulique (1) débrayable en fonction de l'état de vieillissement estimé.
