Abstract

Un procédé contrôle le fonctionnement de moyens de recharge d'un accumulateur hydraulique d'un actionneur hydraulique d'une boîte de vitesses pilotée d'un véhicule comprenant un moteur thermique et propre à fonctionner dans des premier et second modes dans lesquels ledit moteur thermique est respectivement en fonctionnement et arrêté. Ce procédé comprend une étape (20-50) dans laquelle, en présence d'un besoin de recharge de l'accumulateur hydraulique résultant d'une détection dans ce dernier d'une pression inférieure à un premier seuil prédéfini, on attend que la pression devienne inférieure à un deuxième seuil prédéfini, strictement inférieur au premier seuil, lorsque le véhicule est dans le second mode, puis on actionne les moyens de recharge pour que la pression de l'accumulateur hydraulique devienne supérieure à un troisième seuil prédéfini, strictement supérieur au premier seuil.A method controls the operation of means for recharging a hydraulic accumulator of a hydraulic actuator of a controlled gearbox of a vehicle comprising a heat engine and able to operate in first and second modes in which said heat engine is respectively in operation and stopped. This method comprises a step (20-50) in which, in the presence of a need for recharging the hydraulic accumulator resulting from detection in the latter of a pressure below a first predefined threshold, the pressure is waited for becomes lower than a second predefined threshold, strictly lower than the first threshold, when the vehicle is in the second mode, then the recharging means are actuated so that the pressure of the hydraulic accumulator becomes higher than a third predefined threshold, strictly higher than the first threshold.
