Abstract

Selon la présente invention, une unité de commande BLE (61) reçoit à la fois un premier signal, qui est émis sans fil par diffusion par un dispositif embarqué lorsque le dispositif embarqué détermine que quelqu'un est présent dans le véhicule, et un deuxième signal, qui est émis sans fil par diffusion par le dispositif embarqué lorsque le dispositif embarqué détermine que personne n'est présent dans le véhicule. Une unité de traitement de signal (62) mesure les intensités de signal du premier signal reçu et du deuxième signal reçu. D'après les intensités de signal du premier signal reçu et du deuxième signal reçu, une unité de détermination de notification (64) détermine si un dispositif terminal mobile (20) se trouve ou non dans le véhicule. De plus, l'unité de détermination de notification (64) émet un avertissement indiquant que le dispositif terminal mobile (20) a été oublié, si l'unité de détermination de notification (64) détermine que le dispositif terminal mobile (20) se trouve dans le véhicule.
