Title (DE) VERFAHREN ZUR REDUKTION EINER ANTRIEBSLEISTUNG EINES FAHRZEUGANTRIEBS
(EN) METHOD FOR REDUCING THE DRIVE POWER OF A VEHICLE DRIVE
(FR) PROCÉDÉ DE RÉDUCTION DE LA PUISSANCE DU MÉCANISME D'ENTRAÎNEMENT D'UN VÉHICULE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Reduktion einer Antriebsleistung eines Fahrzeugantriebs mit Erfassen (101) eines Temperaturunterschieds zwischen einer Temperatur zumindest einer Komponente des Fahrzeugsantriebs und einem Temparaturschwellwert, Erfassen (103) eines gegenwärtigen Fahrzustandes des Fahrzeugantriebs, Feststellen (105), ob der gegenwärtige Fahrzustand eine Reduktion der Antriebsleistung zulässt oder nicht zulässt, und Reduzieren (107) der Antriebsleistung des Fahrzeugantriebs zur Senkung der Temperatur der zumindest einen Komponente, um den Temperaturunterschied zu erhöhen, falls der gegenwärtige Fahrzustand die reduzierte Antriebsleistung zulässt.
(EN) The invention relates to a method for reducing the drive power of a vehicle drive, comprising the steps of detecting (101) a temperature difference between a temperature of at least one component of the vehicle drive and a temperature threshold value, detecting (103) a current driving state of the vehicle drive, determining (105) whether the current driving state permits or does not permit a reduction of the drive power, and reducing (107) the drive power of the vehicle drive in order to lower the temperature of the at least one component in order to increase the temperature difference, if the current driving state permits the reduced drive power.
(FR) L'invention concerne un procédé de réduction de la puissance du mécanisme d'entraînement d'un véhicule, comprenant les étapes consistant à déterminer (101) une différence de température entre une température d'au moins un composant du mécanisme d'entraînement du véhicule et un seuil de température, à déterminer (103) un état courant de fonctionnement du mécanisme d'entraînement du véhicule, à établir (105) si l'état courant de fonctionnement autorise ou non une réduction de la puissance d'entraînement, et à réduire (107) la puissance du mécanisme d'entraînement du véhicule afin de réduire la température dudit au moins un composant afin d'augmenter la différence de température si l'état courant de fonctionnement autorise la puissance d'entraînement réduite.
