Abstract

Procédé de contrôle automatique de freins d'un véhicule lors d’un démarrage sur une pente avec une vitesse de déplacement suivant une direction prévue présentant un signe demandé (SgnDem), ce procédé recevant une information sur la valeur de la pente, et sur la vitesse de déplacement mesurée du véhicule présentant un signe de vitesse véhicule (SgnVit), pour établir un gradient prédéterminé de desserrage des freins en fonction d’une consigne de couple de traction, lors d’un démarrage du véhicule en pente, si le procédé obtient un signe de vitesse véhicule (SgnVit) inverse au signe demandé (SgnDem), pendant une durée de temps définie il arrête le desserrage des freins pour maintenir le serrage à un niveau constant, puis à la fin de cette durée définie il compare le signe de vitesse véhicule (SgnVit) avec le signe demandé (SgnDem) pour maintenir le serrage des freins, ou appliquer un gradient de desserrage. Figure 3Method for automatically controlling the brakes of a vehicle when starting off on a slope with a speed of movement in a planned direction presenting a requested sign (SgnDem), this method receiving information on the value of the slope, and on the measured displacement speed of the vehicle exhibiting a vehicle speed sign (SgnVit), to establish a predetermined brake release gradient as a function of a traction torque setpoint, when starting the vehicle on a slope, if the method obtains a vehicle speed sign (SgnVit) inverse to the requested sign (SgnDem), for a defined period of time it stops the release of the brakes to maintain the application at a constant level, then at the end of this defined period it compares the sign of vehicle speed (SgnVit) with the sign requested (SgnDem) to maintain brake application, or apply a release gradient.
