Abstract

L'invention concerne une méthode de communication de données numériques entre plusieurs organes électriques d’un véhicule automobile électrifié (1), via un bus de communication, la méthode de communication comportant une transformation de la capacité du nombre représentatif de la donnée numérique à transmettre via le bus de communication afin de réduire ladite capacité d’au moins un chiffre et de pouvoir transmettre ainsi de plus grands nombres sans modifier la structure du bus de communication ou son protocole de communication. Cette transformation est réalisée en amont du bus de communication, et une transformation inverse est appliquée en aval du bus de communication afin de retrouver le nombre initial représentatif de la donnée numérique transmise.
