Title
(EN) METHOD FOR CONTROLLING AN ADAPTIVE CRUISE CONTROL
(FR) PROCEDE DE PILOTAGE D'UN REGULATEUR DE VITESSE ADAPTATIF
Abstract
(EN) The invention relates to a method for controlling an adaptive cruise control of a motor vehicle equipped with a braking system (3). A torque setpoint (CC) at the engine and a braking setpoint (CF) are delivered, with monitoring of the torque setpoint (CC) and/or of a torque (CR) at the wheel being carried out. At least one maximum threshold of torque setpoint (CC) and of engine torque (CR) at the wheel is determined. When a torque setpoint (CC) at the engine and a braking setpoint (CF) are launched in parallel and the maximum threshold is exceeded, a time count is initiated and, if a maximum predetermined duration of parallel launching of the setpoints with the maximum threshold being exceeded is reached, operation is carried out in a downgraded control mode of the control, with the torque setpoint (CC) being cancelled.
(FR) L'invention concerne un procédé de pilotage d'un régulateur de vitesse adaptatif d'un véhicule à moteur équipé d'un système de freinage (3). Il est délivré une consigne de couple (CC) au moteur et une consigne de freinage (CF) avec des suivis de la consigne de couple (CC) et/ou d'un couple à la roue (CR) effectivement réalisé. Il est déterminé au moins un seuil maximal de consigne de couple (CC) et de couple moteur à la roue (CR) avec, dès qu'une consigne du couple au moteur (CC) et une consigne de freinage (CF) sont lancées en parallèle et que le seuil maximal est dépassé, il est initié un comptage de temps et si une durée maximale prédéterminée de lancement en parallèle des consignes avec dépassement du seuil maximal est atteinte, il est procédé en un fonctionnement en mode dégradé de pilotage du régulateur avec annulation de la consigne de couple (CC).
