Abstract

La présente invention permet de supprimer les inconvénients dus à une faible expiration dans un dispositif générant un aérosol.　Une unité (152) d'acquisition de données de pression reçoit des données concernant la pression à l'intérieur du dispositif générant un aérosol, et une première unité (252) de détermination d'aspiration détermine si la différence entre la pression acquise et une pression de référence est inférieure ou égale à une première valeur seuil d'évaluation de l'aspiration, afin d'évaluer la présence ou l'absence d'aspiration d'un utilisateur. Une unité (254) de détermination d'expiration détermine, dans le cas où l'évaluation de la première unité (252) de détermination d'aspiration est telle que la différence entre la pression acquise et la pression de référence est inférieure ou égale à la première valeur seuil d'évaluation de l'aspiration, si la différence entre la pression de référence la plus récente et une pression de référence à un moment donné dans le passé est inférieure ou égale à une valeur seuil d'évaluation d'expiration pour évaluer la présence ou de l'absence d'expiration de l'utilisateur. Dans le cas où l'évaluation de l'unité (254) de détermination d'expiration est telle que la différence entre la pression de référence la plus récente et une pression de référence à un moment donné dans le passé est inférieure ou égale à une valeur seuil d'évaluation d'expiration, le dispositif générant un aérosol est mis en état de mise en oeuvre et génère un aérosol dans l'unité (258) de génération d'aérosol.
