review text: On sait depuis 1976 qu'il existe un lien entre systèmes de champs de vecteurs réels et groupes nilpotents. On montre ici que ce phénomène s'étend aux systèmes d'opérateurs pseudo- différentiels à symboles principaux réels. Une équivalence de propriétés est conjecturée, mais seule l'une des implications est ici démontrée.
