Title (EN) METHOD FOR OPERATING A HYBRID VEHICLE
(FR) PROCÉDÉ PERMETTANT DE FAIRE FONCTIONNER UN VÉHICULE HYBRIDE
(DE) VERFAHREN ZUM BETREIBEN EINES HYBRIDFAHRZEUGS
Abstract:
(EN) The invention relates to a method for operating a hybrid drive, wherein at least two power units (10, 12) work together in a driving manner and one energy accumulator is at least intermittently charged by one of the power units (12) one of the power units (12) is at least intermittently supplied with drive energy by the energy accumulator. The power unit (12) produces a desired power (Pelsoll). According to the invention, required desired-drive torque (Msoll) of the drive is produced and, simultaneously, the desired power (Pelsoll) of the engine (12) is maintained at the temporal mean. Deviations of the desired power (Pelsoll) are permitted in accordance with current operating points of the power unit (10, 12). This enables fuel consumption to be optimised.
(FR) Procédé permettant de faire fonctionner un entraînement hybride, selon lequel au moins deux unités (10, 12) coopèrent en matière d'entraînement, un accumulateur d'énergie est chargé au moins temporairement par l'une des unités (12) et l'une des unités (12) est alimentée au moins temporairement en énergie d'entraînement par l'accumulateur d'énergie, l'unité (12) produisant une puissance idéale (Pel soll). Selon la présente invention, un couple idéal désiré (Msoll) de l'entraînement est produit et simultanément, la puissance idéale (Pel soll) de l'unité (12) est maintenue dans la moyenne temporelle, des écarts par rapport à la puissance idéale (Pel soll) étant autorisés en fonction des points de fonctionnement effectifs des unités (10, 12). Cela permet une optimisation de la consommation de carburant .
(DE) Die Erfindung geht aus von einem Verfahren zum Betreiben eines Hybridantriebs, bei dem wenigstens zwei Aggregate (10, 12) antriebsmäßig zusammenwirken und wenigstens zeitweise ein Energiespeicher von einem der Aggregate (12) geladen und wenigstens zeitweise eines der Aggregate (12) vom Energiespeicher mit Antriebsenergie versorgt wird, wobei das Aggregat (12) eine Soll-Leistung (Pelsoll) erzeugt. Es wird vorgeschlagen, dass ein angefordertes Soll-Antriebsmoment (Msoll) des Antriebs erzeugt und gleichzeitig die Soll-Leistung (Pelsoll) des Aggregats (12) im zeitlichen Mittel eingehalten wird, wobei Abweichungen von der Soll-Leistung (Pelsoll) in Abhängigkeit von aktuellen Betriebspunkten der Aggregate (10, 12) zugelassen werden. Dies dient der Optimierung des Kraftstoffverbrauchs .
