Title
(EN) METHOD OF AND APPARATUS FOR MONITORING THE PERFORMANCE OF A VEHICLE BRAKING SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF DE SURVEILLANCE DE L’EFFICACITÉ DU SYSTÈME DE FREINAGE D’UN VÉHICULE
Abstract
(EN) A method of providing an indication of the performance of the braking system of a vehicle comprising a tractor and a trailer in which, during a braking event, a braking control pressure signal is generated in response to driver demand for braking, the braking control pressure signal indicating a braking control pressure which is representative of the degree of braking required by the driver, and is transmitted to braking systems provided on the tractor and trailer, the method including the steps of determining an average value of the braking control pressure during the braking event, determining an average value of the vehicle deceleration during the braking event, and using both the average braking control pressure and average vehicle deceleration to assign the braking event to one of a plurality of categories.
(FR) L’invention concerne un procédé permettant d’indiquer l’efficacité du système de freinage d’un véhicule comprenant un véhicule tracteur et une remorque. Le procédé comprend la production, pendant un événement de freinage, d’un signal de pression de commande de freinage en réponse à une demande de freinage provenant du conducteur, ledit signal indiquant une pression de commande de freinage représentant le degré de freinage requis par le conducteur ; et la transmission de ce signal à des systèmes de freinage prévus sur le véhicule tracteur et la remorque. Le procédé comprend les étapes consistant à : déterminer une valeur moyenne de la pression de commande de freinage pendant l’événement de freinage, déterminer une valeur moyenne de la décélération du véhicule pendant l’événement de freinage et utiliser la pression moyenne de commande de freinage et la décélération moyenne du véhicule pour classer l’événement de freinage dans une d’une pluralité de catégories.
