Title
(EN) DEVICE FOR DETECTING A USER'S INTENTION TO LOCK OR UNLOCK A MOTOR VEHICLE DOOR AND ASSOCIATED DOOR HANDLE
(FR) DISPOSITIF DE DÉTECTION D'INTENTION DE VERROUILLAGE OU DE DÉVERROUILLAGE D'UNE PORTIÈRE DE VÉHICULE AUTOMOBILE PAR UN UTILISATEUR ET POIGNÉE DE PORTIÈRE ASSOCIÉE
Abstract
(EN)
The present invention concerns a device (D') for detecting a user's intention to lock or unlock a motor vehicle door (10'), said device (D') being included in a sealed housing (B'), incorporated into a handle (10') that is not sealed and the lower part of which comprises discharge holes (t1, t2), part of the housing (B') being submerged in water (e), said device (D') comprising: • a capacitive sensor (100) for detecting approach and/or contact, comprising at least one detection electrode (E2'), having a variable-value detection capacitor (Ce), the capacitance of which is representative of the approach of the hand (M) of a user, • a charge/discharge capacitor (Cs), the invention proposing the addition of a protection electrode Ep situated in the part of the housing that is submerged in water, coupled electrically to the detection electrode and connected to a terminal of the charge/discharge capacitor Cs such that the protection electrode Ep is simultaneously at the same potential as the terminal of the charge/discharge capacitor during the different stages of charging/discharging the detection capacitor and the charge/discharge capacitor that are necessary in order to estimate the value of the detection capacitor.
(FR)
La présente invention a pour objet un dispositif de détection (D') d'intention de verrouillage ou de déverrouillage d'une portière (10') de véhicule automobile par un utilisateur, ledit dispositif (D') étant compris dans un boîtier étanche (B'), intégré dans une poignée (10') non étanche et dont la partie inférieure comprend des trous d'évacuation (t1, t2), une partie du boîtier (B') se trouvant immergée dans l'eau (e), ledit dispositif (D') comprenant: • un capteur capacitif de détection d'approche et/ou de contact (100), comprenant au moins une électrode de détection (E2'), présentant une capacité de détection (Ce) variable représentative de l'approche de la main (M) d'un utilisateur, • une capacité de charge/décharge (Cs), l'invention proposant l'ajout d'une électrode de protection Ep située dans la partie du boîtier qui est immergée dans l'eau, couplée électriquement à l'électrode de détection et connectée à une borne de la capacité de charge/décharge Cs de telle manière que l'électrode de protection Ep soit simultanément au même potentiel que la borne de la capacité de charge/décharge durant les différentes étapes de charge/décharge de la capacité de détection et de la capacité de charge /décharge qui sont nécessaires à l'estimation de la valeur de la capacité de détection.
