Abstract
(EN) The invention relates to a method for checking the operation of a vehicle surface cleaning device (2) intended to be mounted on a motor vehicle, the method comprising, at least once, the following steps: a command to activate a pump (6) in order to inject cleaning liquid to at least one valve (12) during a determined period of time, the command to activate the pump (6) in order to inject liquid to an inlet orifice of the valve (12) being coupled with maintaining the valve or valves (12) in a closed state; at least one measurement of a parameter relating to the pressure of the cleaning liquid in one segment of the fluid distribution circuit (8) located upstream of the valve or valves (12) by at least one pressure sensor (16); comparison of the measured pressure-related parameter with a predetermined expected value; determination of an operating state of the cleaning device (2) according to the result of the comparison between the measured pressure-related parameter and the predetermined expected value; and generation of an alarm signal in the event of a malfunction of the cleaning device (2).
(FR) L'invention concerne un procédé de vérification du fonctionnement d'un dispositif de nettoyage (2) de surface de véhicule destiné à être monté sur un véhicule automobile, le procédé comprenant, au moins une fois, les étapes suivantes : - commande d'activation d'une pompe (6) pour injecter du liquide de nettoyage jusqu'à au moins une vanne (12) durant une période de temps déterminée, la commande d'activation de la pompe (6) pour injecter du liquide jusqu'à un orifice d'entrée de la vanne (12) étant couplée au maintien d'un état fermé de la ou des vanne(s) (12), - au moins une mesure d'un paramètre relatif à la pression du liquide de nettoyage dans un segment du circuit de distribution fluidique (8) localisé en amont de la ou des vanne(s) (12) par au moins un capteur de pression (16), - comparaison du paramètre relatif à la pression mesuré à une valeur attendue prédéterminée, et - détermination d'un état de fonctionnement du dispositif de nettoyage (2) en fonction du résultat de comparaison entre le paramètre relatif à la pression mesuré à la valeur attendue prédéterminée, et - génération d'un signal d'alerte en cas de dysfonctionnement du dispositif de nettoyage (2).
