Abstract

L'invention concerne un dispositif et un procédé pour distribuer de l'air et/ou un agent d'étanchéité à un pneu d'un véhicule. L'alimentation électrique du compresseur d'air s'effectue par l'intermédiaire d'un port USB alimenté au lieu d'une prise allume-cigare 12 V typique. La position du pneu gonflé peut également être déterminée par l'intermédiaire de l'interface de données du port USB. Par communication entre le compresseur et l'interface des systèmes du véhicule, le compresseur peut automatiquement s'éteindre lorsque la pression de pneu recommandée a été atteinte.
