Title (DE) BORDNETZ FÜR EIN FAHRZEUG UND VERFAHREN ZUM EINSPAREN VON ENERGIE
(EN) ONBOARD NETWORK FOR A VEHICLE AND METHOD FOR SAVING ENERGY
(FR) RÉSEAU DE BORD POUR UN VÉHICULE ET PROCÉDÉ PERMETTANT DE RÉALISER DES ÉCONOMIES D'ÉNERGIE
Abstract:
(DE) Die Erfindung betrifft ein Bordnetz (1) für ein Fahrzeug (32), insbesondere Kraftfahrzeug. Das Bordnetz (1) weist eine mindestens zum Generatorbetrieb ausgebildete elektrische Maschine (10) auf. Das Bordnetz (1) weist auch einen eingangsseitig mit der elektrischen Maschine (10) mindestens mittelbar verbundenen Spannungswandler (12) und einen ausgangsseitig mit dem Spannungswandler (12) verbundenen ersten Energiespeicher (14), insbesondere einen Akkumulator auf. Die elektrische Maschine (10) ist zum Rekuperationsbetrieb ausgebildet. Der Spannungswandler (12) ist ausgebildet, einen Ladezustand des ersten Energiespeichers (14) zu erfassen oder zu begrenzen und den Ladezustand des ersten Energiespeichers (14) derart zu regeln, dass der erste Energiespeicher (14) während eines Generatorbetriebs, bevorzugt beim energieverbrauchenden Fahren des Fahrzeugs, eine Reservekapazität (15) aufweist. Der Spannungswandler (12) ist weiter ausgebildet, in Abhängigkeit eines eingangsseitig empfangenen, einen Rekuperationsbetrieb des Fahrzeugs (32) repräsentierenden Rekuperationssignals (23) die Reservekapazität (15) des ersten Energiespeichers (14) zu laden.
(EN) The invention relates to an onboard network (1) for a vehicle (32), in particular a motor vehicle. The onboard network (1) comprises an electric machine (10) designed for operating in generator mode. The onboard network (1) further comprises a voltage transformer (12) that is at least indirectly connected to the electric machine (10) on the input side and a first energy accumulator (14) connected to the voltage transformer (12) on the output side, in particular an accumulator. The electric machine (10) is designed for the recuperation operation. The voltage transformer (12) is designed to detect or limit a charge state of the first energy accumulator (14) and to regulate the charge state of the first energy accumulator (14) such that the first energy accumulator (14) has a reserve capacity (15) during generator operation, preferably when driving the vehicle in an energy-consuming manner. The voltage transformer (12) is further designed to charge the reserve capacity (15) of the first energy accumulator (14) depending on a recuperation signal (23) received on the input side and representing a recuperation operation of the vehicle (32).
(FR) L'invention concerne un réseau de bord (1) pour un véhicule (32), en particulier un véhicule automobile. Le réseau de bord (1) présente une machine électrique (10) conçue au moins pour fonctionner en mode générateur. Le réseau de bord (1) présente également un transformateur de tension (12) relié au moins indirectement côté entrée à la machine électrique (10) et un premier réservoir d'énergie (14) relié côté sortie au transformateur de tension (12), ce premier réservoir étant en particulier un accumulateur. La machine électrique (10) est conçue pour fonctionner en mode récupération. Le transformateur de tension (12) est conçu pour détecter ou limiter un état de charge du premier réservoir d'énergie (14) et pour régler l'état de charge du premier réservoir d'énergie (14) de sorte que ce dernier présente une capacité de réserve (15) pendant un fonctionnement en mode générateur, de préférence lors d'une conduite du véhicule entraînant une consommation d'énergie. Le transformateur de tension (12) est en outre conçu pour charger la capacité de réserve (15) du premier réservoir d'énergie (14), en fonction d'un signal de récupération (23) reçu côté entrée, représentant un mode récupération du véhicule (32).
