Abstract

Selon la présente invention, une unité (101) d'acquisition de température d'air de soufflage acquiert la température de l'air de soufflage, en tant que température d'air de soufflage, au niveau de chaque orifice parmi une pluralité d'orifices de soufflage destinés à souffler de l'air en provenance d'un climatiseur. Une unité (103) de sélection représentative sélectionne un orifice de soufflage représentatif parmi la pluralité d'orifices de soufflage, en fonction de la température de l'air de soufflage acquise par l'unité (101) d'acquisition de température d'air de soufflage. Une unité (104) de commande de fonctionnement commande le fonctionnement du climatiseur en fonction de la température de l'air de soufflage au niveau de l'orifice de soufflage représentatif.
