Title
(EN) OCCUPANT SENSOR
(FR) DETECTEUR D'OCCUPANT
Abstract
(EN)
An electric field sensor comprises (100) at least one electrode (103) mountable in a vehicle seat (3) and a sensing circuit (106) operatively coupled to the electrode (103), wherein the at least one electrode (103) at least partially bounds at least one region (112) that is proximate to an object such as an infant seat (600), a child seat, or a booster seat, for which the sensitivity of the sensor is preferably reduced. The at least one region (112) without a conductive electrode may comprise a plurality of regions (112), and at least one of the regions (112) may extend laterally across the seat (3). Furthermore, a plurality of electrodes (103) may be incorporated, each having a different sensitivity to particular objects to be sensed, wherein an overall capacitance measurement that is dominated by the capacitance of the particular electrode (103) that is most sensitive to the particular object can be used to indicate the presence of that object.

Selon cette invention, un détecteur de champ électrique comprend (100) au moins une électrode (103) se fixant dans un siège (3) de véhicule et un circuit (106) de détection couplé de manière fonctionnelle à l'électrode (103). Cette électrode (103) se fixe au moins partiellement à une région (112) proche d'un objet tel qu'un siège (600) de bébé, un siège d'enfant ou un siège d'appoint pour lesquels la sensibilité du détecteur est de préférence réduite. La région (112) sans électrode conductrice peut comprendre une pluralité de régions (112), et au moins une de ces régions (112) peut s'étendre latéralement dans le siège (3). Il est également possible d'incorporer une pluralité d'électrodes (103) de sensibilité différente à des objets particuliers devant être détectés. On peut utiliser une mesure de la capacitance globale dominée par la capacitance de l'électrode (103) spécifique plus sensible à l'objet spécifique pour indiquer la présence d'un objet.
