Abstract

La présente invention concerne un procédé de détermination d’une consigne de vitesse (CSREG) pour un régulateur de vitesse de véhicule automobile pour assister le conducteur lors du franchissement d’une voie en montée, comprenant le calcul (21) en continu des valeurs instantanées de la vitesse (V) et de la pente (PI) de la voie, la détection (22) d’une situation de déplacement du véhicule sous l’action dudit régulateur de vitesse par une première valeur (CS1) de consigne de vitesse (CSREG), l’enregistrement (24) d’un paramètre de pente (PI0), la détermination (25-29) d’une deuxième valeur (CS2) prédéterminée de consigne de vitesse (CSREG) en fonction d’au moins ledit paramètre de pente (PI0), l’enregistrement (24) dudit paramètre de pente (PI0) étant exécuté lors de la détection (23) d’un instant durant lequel la valeur instantanée de la vitesse (V) est égale à 0 km/h simultanément à une valeur de la pente instantanée (PI) supérieure à 0. Figure 2The present invention relates to a method for determining a speed setpoint (CSREG) for a motor vehicle speed regulator to assist the driver when crossing an uphill lane, comprising the continuous calculation (21) of the instantaneous values the speed (V) and the slope (PI) of the track, the detection (22) of a situation of displacement of the vehicle under the action of the said speed regulator by a first value (CS1) of speed set point ( CSREG), the recording (24) of a slope parameter (PI0), the determination (25-29) of a second predetermined value (CS2) of the speed setpoint (CSREG) as a function of at least said parameter of slope (PI0), the recording (24) of said slope parameter (PI0) being performed upon detection (23) of an instant during which the instantaneous value of the speed (V) is equal to 0 km/h simultaneously with a value of the instantaneous slope (PI) greater than 0.
