Title
(EN) OCCUPANT CLASSIFICATION SYSTEM
(FR) SYSTÈME DE CLASSIFICATION DE PERSONNES TRANSPORTÉES
Abstract
(EN)
An occupant classification system classifies occupants on a vehicle seat and is capable of separating child seats from adults during wet seat cases. In the system, the seat structure is grounded. The classification system includes a measurement circuit, an identifying circuit, and a controller. The measurement circuit is configured to measure in-phase and quadrature components of a current sent out to the sensing element. The identifying circuit is configured to identify if a seat pan and a seat back frame of the vehicle seat are grounded to a circuit ground. The controller is configured to use measurements of the measurement circuit to classify the occupant. The sensing element can be located in a sensing mat that further includes a heating element.

L'invention concerne un système de classification de personnes transportées destiné à classer des personnes transportées assises sur un siège de véhicule. Ce système permet d'effectuer une distinction entre des enfants et des adultes assis sur des sièges mouillés. Dans ce système, la structure de siège est mise à la terre. Ce système de classification comprend un circuit de mesure, un circuit d'identification et un contrôleur. Le circuit de mesure est conçu pour mesurer des composants en phase et en quadrature d'un courant envoyé à l'élément de détection. Le circuit d'identification de l'invention est conçu pour identifier si la partie d'assise du siège et si l'ossature du dossier du siège sont mises à la terre à l'aide d'une masse de circuit. Le contrôleur est conçu pour classifier les types d'occupant à l'aide des mesures du circuit de mesure. L'élément de détection peut être monté dans une nappe de détection qui comprend également un élément chauffant.
