Abstract[English]
A method and system for providing maximum trailer braking during a high pressure demand, such as during autonomous emergency braking (AEB), for tractor- trailers is provided. The system can include a brake controller of the trailer that uses only tractor anti-lock brake system (ABS) data from the tractor wheels, without using any trailer ABS information, to estimate the surface friction and generate a high or low pressure command to be sent to the trailer based on only the tractor ABS data. The estimation of surface friction may be accomplished using the ABS information from the tractor and the pressure being demanded to determine a percent reduction of pressure requested by the tractor that may be compared to a threshold percentage to differentiate between high and low mu surfaces in real time.[French]
L'invention concerne un procédé et un système pour fournir un freinage de remorque maximal pendant une demande de haute pression, telle que pendant un freinage d'urgence automatique (FUA), pour des camions à semi-remorque. Le système peut comprendre un dispositif de commande de frein de la remorque qui utilise uniquement des données de système de frein antiblocage (ABS) de tracteur routier provenant des roues de tracteur routier, sans utiliser d'informations ABS de remorque, pour estimer le frottement de surface et générer une commande haute ou basse pression à envoyer à la remorque sur la base uniquement des données ABS de tracteur routier. L'estimation du frottement de surface peut être accomplie à l'aide des informations ABS provenant du tracteur routier et la pression étant demandée pour déterminer un pourcentage de réduction de la pression demandée par le tracteur routier qui peut être comparé à un pourcentage seuil pour différencier en temps réel des surfaces mu élevée et faible.
