Title
(EN) SYSTEM FOR CLEANING AT LEAST TWO SENSORS/TRANSMITTERS FOR A MOTOR VEHICLE
(FR) SYSTÈME DE NETTOYAGE D'AU MOINS DEUX CAPTEURS/ÉMETTEURS D'UN VÉHICULE AUTOMOBILE
Abstract
(EN)
The invention relates to a system for cleaning (100) sensors/transmitters (200, 300) for a motor vehicle, in which a control unit (140) is configured to receive a piece of information (210, 310) requesting activation of a first and/or a second projection device (150, 160) in order to determine a theoretical value of an operating parameter of a pump (120) as a function, on one hand, of a length of a portion of the distribution circuit (130) extending between a reservoir (110) and the first and/or second projection devices (150, 160) to be activated, and on the other hand, of a desired operating pressure of the first and/or second projection device(s) (150, 160) in order to compare the theoretical value (120) with an actual value (120) and in order to determine a status of the portion of the distribution circuit (130) as a function of the result of the comparison.
(FR)
L'invention a pour objet un système de nettoyage (100) de capteurs/émetteurs (200, 300) d'un véhicule automobile, dans lequel une unité de contrôle (140) est configurée pour recevoir une information (210, 310) de demande d'activation d'un premier et/ou d'un deuxième dispositifs de projection (150, 160), pour déterminer une valeur théorique d'un paramètre de fonctionnement d'une pompe (120) en fonction, d'une part, d'une longueur d'une portion du circuit de distribution (130) s'étendant entre un réservoir (110) et le premier et/ou le deuxième dispositifs de projection (150, 160) à activer, et d'autre part, d'une pression de fonctionnement souhaitée du premier et/ou du deuxième dispositif(s) de projection (150, 160), pour comparer ladite valeur théorique (120) avec une valeur réelle (120) et pour déterminer un état de ladite portion du circuit de distribution (130) en fonction du résultat de ladite comparaison.
