Title
(EN) METHOD AND DEVICE FOR CONTROLLING DECELERATION IN A HYBRID PHASE, FOR A SELF-DRIVING VEHICLE AND NON-COMBUSTION POWER UNIT
(FR) PROCÉDÉ ET DISPOSITIF DE CONTRÔLE DE DÉCÉLÉRATION À PHASE MIXTE, POUR UN VÉHICULE À CONDUITE AUTOMATISÉE ET MACHINE MOTRICE NON-THERMIQUE
Abstract
(EN)
A method for controlling the deceleration of a partially self-driving vehicle comprising a non-combustion power unit supplying torque to an axle assembly or decelerating same by recovering energy from the axle assembly according to a torque setpoint, and a braking system decelerating same according to a deceleration setpoint. This method comprises a step (10-50) in which, in the event of a need to decelerate during a self-driving phase, the torque setpoint is determined as a function of a minimum authorised torque and of constraints until this torque is reached, and the deceleration setpoint is determined as a function of the constraints and from a chosen first instant preceding a second instant at which the minimum authorised torque is reached, so that, between the first and second instants, the deceleration is the result of the recovery of energy and of the braking system.
(FR)
Un procédé contrôle la décélération d'un véhicule à conduite partiellement automatisée et comprenant une machine motrice non-thermique fournissant du couple pour un train ou induisant sa décélération par récupération d'énergie sur le train en fonction d'une consigne de couple, et un système de freinage le décélérant en fonction d'une consigne de décélération. Ce procédé comprend une étape (10-50) dans laquelle, en cas de besoin d'une décélération pendant une phase de conduite automatisée, on détermine la consigne de couple en fonction d'un couple minimal autorisé et de contraintes jusqu'à ce que ce dernier soit atteint, et on détermine la consigne de décélération en fonction des contraintes et à partir d'un premier instant choisi précédant un second instant où le couple minimal autorisé est atteint, afin que la décélération résulte de la récupération d'énergie et du système de freinage entre les premier et second instants.
