Abstract

L'invention concerne un procédé de surveillance d'une température de freinage (TBR) d'une remorque (11) d'un ensemble camion/véhicule (27), dans lequel la remorque (11) est freinée par un dispositif de freinage (9) agissant uniquement sur la remorque (11), une température (TBR) d'un frein de roue (23) de la remorque (11) étant contrôlée. Dans un procédé, une température de frein de roue (TBRS) de la remorque (11) est estimée à partir d'une surveillance d'une pression de frein de remorque (pBAnh), qui est contrôlée par un véhicule tracteur (3) de l'ensemble camion/véhicule (27), et lorsqu'une valeur de seuil de température (TSW) est dépassée par la température estimée des freins de roue (TBRS), le dispositif de freinage (9) agissant uniquement sur la remorque (11) est désactivé.
