Abstract

Procédé de nettoyage à air pulsé pour dispositif de détection La présente invention concerne un procédé de nettoyage (100) à air pulsé pour dispositif de détection d’un véhicule, au cours duquel : - à une première étape (101), on met en fonctionnement un compresseur d’air de manière à atteindre un seuil de pression (71) dans une réserve d’air, - à une deuxième étape (102), à l’atteinte de ce seuil de pression (71), on projette de manière répétitive un flux d’air vers le dispositif de détection par l’intermédiaire d’une buse de projection. L’invention couvre également un dispositif de nettoyage mettant en œuvre ledit procédé de nettoyage (100) ainsi qu’un système de détection comprenant un dispositif de détection et un tel dispositif de nettoyage. (figure 3)The present invention relates to a pulsed air cleaning method (100) for the detection device of a vehicle, during which: - in a first step (101), operation is started an air compressor so as to reach a pressure threshold (71) in an air supply, - in a second step (102), on reaching this pressure threshold (71), the a flow of air towards the detection device via a projection nozzle. The invention also covers a cleaning device implementing said cleaning method (100) as well as a detection system comprising a detection device and such a cleaning device. (figure 3)
