Abstract

L'invention concerne un procédé de commande d'une transmission (20) hydrostatique de véhicule (10) automobile roulant, le véhicule (10) automobile comportant : - une pompe (22) hydraulique pour mettre sous pression un fluide hydraulique et un moteur (24) hydraulique ; - un premier embrayage (28) à commande hydraulique pour accoupler la pompe (22) hydraulique avec des roues (12) ; - un deuxième embrayage (30) à commande hydraulique pour accoupler le moteur (24) hydraulique avec des roues (14) ; - une pompe (42) électrique qui commande simultanément les deux embrayages (28, 30) ; caractérisé en ce que la transmission (20) hydrostatique est susceptible d'être commandée dans un mode veille (Mv) dans lequel l'unité (46) électronique de commande alimente la pompe (42) électrique avec une puissance électrique intermédiaire (E2) comprise entre une puissance électrique d'ouverture (E0) des embrayages et une puissance électrique de fermeture (E1) des embrayages.The invention relates to a method for controlling a hydrostatic transmission (20) of a rolling motor vehicle (10), the motor vehicle (10) comprising: - a hydraulic pump (22) for pressurizing a hydraulic fluid and a motor ( 24) hydraulic; - a first clutch (28) with hydraulic control for coupling the hydraulic pump (22) with wheels (12); - a second clutch (30) with hydraulic control for coupling the hydraulic motor (24) with wheels (14); - an electric pump (42) which simultaneously controls the two clutches (28, 30); characterized in that the hydrostatic transmission (20) can be controlled in a standby mode (Mv) in which the electronic control unit (46) supplies the electric pump (42) with an intermediate electric power (E2) included between an electric opening power (E0) of the clutches and an electric closing power (E1) of the clutches.
