L'invention concerne un serveur de gestion de pression interne de pneu (20) qui est pourvu : d'une unité de transmission qui, à un moment prédéterminé avant un temps d'initiation de réservation, transmet un signal qui amène un dispositif embarqué (61) monté sur un véhicule (60) à mesurer la pression interne d'un pneu ; une première unité de comparaison qui compare la pression interne reçue en provenance du dispositif embarqué (61) et une première valeur de seuil ; une première unité de notification qui, lorsque la pression interne reçue en provenance du dispositif embarqué (61) est inférieure ou égale à la première valeur de seuil, remplace le véhicule réservé (60) par un autre véhicule (70), et fournit une notification du changement à un dispositif terminal (40) (dispositif terminal portable 41), qui est actionné par un utilisateur et peut utiliser un partage de voiture ; une seconde unité de comparaison qui, lorsque la pression interne est supérieure à la première valeur de seuil, compare la pression interne et une seconde valeur de seuil ; et une seconde unité de notification qui, lorsque la pression interne est inférieure ou égale à la seconde valeur de seuil, fournit une notification selon laquelle la pression interne est inférieure à une valeur prescrite.
