Abstract

Système de détection de présence d’une personne (1) occupant un siège arrière (2) d’un véhicule (3), comportant : - un dispositif de démarrage du véhicule (3), de type mains libres, destiné à être activé par un premier signal Bluetooth ; - des antennes de réception (4a, 4b, 4c), agencées autour des sièges arrière (2) pour recevoir le premier signal Bluetooth, et comprenant chacune un équipement (40) configuré pour transmettre la puissance mesurée du premier signal Bluetooth reçu par l’antenne de réception (4a, 4b, 4c) correspondante ; les équipements (40) étant configurés pour communiquer entre eux via un deuxième signal (S2) Bluetooth ; - une unité de traitement (5) de données, configurée pour : mesurer les bilans de liaison du deuxième signal (S2) Bluetooth entre les antennes de réception (4a, 4b, 4c), comparer les bilans de liaison mesurés à une situation de référence où les sièges arrière (2) sont libres. Figure 1System for detecting the presence of a person (1) occupying a rear seat (2) of a vehicle (3), comprising: - a vehicle starting device (3), of the hands-free type, intended to be activated by a first Bluetooth signal; - reception antennas (4a, 4b, 4c), arranged around the rear seats (2) to receive the first Bluetooth signal, and each comprising a device (40) configured to transmit the measured power of the first Bluetooth signal received by the corresponding receiving antenna (4a, 4b, 4c); the devices (40) being configured to communicate with each other via a second Bluetooth signal (S2); - a data processing unit (5), configured to: measure the link budgets of the second Bluetooth signal (S2) between the reception antennas (4a, 4b, 4c), compare the measured link budgets with a reference situation where the rear seats (2) are free.
