Title (EN) METHOD AND DEVICE FOR CONTROLLING THE BRAKING ENERGY RECOVERY FUNCTION OF A HYBRID VEHICLE ON A DOWNWARD SLOPE
(FR) PROCÉDÉ ET DISPOSITIF DE CONTRÔLE DE LA FONCTION DE RÉCUPÉRATION D'ÉNERGIE DE FREINAGE D'UN VÉHICULE HYBRIDE DANS UNE PENTE DESCENDANTE
Abstract:
(EN) The invention relates to a method for controlling a braking energy recovery function of a vehicle (V) comprising a driver-controlled accelerator pedal and a hybrid drive chain including a non-thermal prime mover (MM) with reversible operation. The method comprises a step (10-70) in which the vehicle (V) determines the vehicle acceleration at a time t0 and, when the vehicle (V) is travelling, or preparing to travel, on a downward slope and the driver is no longer pressing on the accelerator pedal, the vehicle (V) determines a braking energy recovery torque suitable for at least partially cancelling the determined acceleration, and controls the prime mover (MM) such that it recovers the braking energy according to the determined torque.
(FR) Un procédé permet de contrôler une fonction de récupération d'énergie de freinage d'un véhicule (V) comportant une pédale d'accélérateur contrôlée par un conducteur et une chaîne de transmission hybride comportant une machine motrice (MM) non thermique et à fonctionnement réversible. Ce procédé comprend une étape (10-70) dans laquelle le véhicule (V) détermine son accélération à un instant t0, et, lorsque le véhicule (V) circule, ou s'apprête à circuler, sur une voie de circulation en pente descendante et que le conducteur n'appuie plus sur la pédale d'accélérateur, le véhicule (V) détermine un couple de récupération d'énergie de freinage propre à annuler au moins partiellement cette accélération déterminée, puis contrôle la machine motrice (MM) de sorte qu'elle récupère l'énergie de freinage selon ce couple déterminé.
