Abstract
Description
ausfallen. Dies hat insbesondere Komforteinbußen zur Folge. Diese Nachteile treten nicht zu Tage, wenn die Nebenaggregate über eigenständige Antriebsquellen verfügen – die Klimaanlage beispielsweise über einen zusätzlichen elektrisch betriebenen Klimakompressor verfügt und die Lenkhilfe beispielsweise über eine separate elektrisch betriebene Pumpe verfügt. Derartige Ausgestaltungen bedingen allerdings neben zusätzlichen Kosten auch Mehrgewicht für das Kraftfahrzeug.fail. This in particular results in loss of comfort. These disadvantages Do not appear if the ancillaries have independent power sources - the air conditioning for example about An additional electrically powered air conditioning compressor and the power steering, for example, via a separate electrically operated pump has. Such embodiments condition, however, in addition to additional Cost also extra weight for the car.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betreiben einer Antriebseinheit mit Brennkraftmaschine und elektrischer Maschine zu schaffen, welches auch bei abgeschalteter Brennkraftmaschine, bei geringem konstruktiven und finanziellen Aufwand, ein Mindestmaß an Komfort gewährleistet.Of the Invention is based on the object, a method for operating a drive unit with internal combustion engine and electric machine create, which also when the internal combustion engine, at low constructive and financial effort, a minimum of comfort guaranteed.
Erfindungsgemäß wird die Aufgabe durch die Gesamtheit der Merkmale des Anspruchs 1 gelöst. Durch den über die elektrische Maschine gewährleisteten Schleppbetrieb der Brennkraftmaschine (während eines sogenannten stand-by-Modus) wird gewährleistet, dass die durch die Brennkraftmaschine angetriebenen Nebenaggregate zumindest in einem Teilbetrieb (ggf. mit verminderter Drehzahl der Brennkraftmaschine) weiter betrieben werden. Gemäß der Erfindung wird während des Schleppbetriebs der bzw. jeder Ventilantrieb der Brennkraftmaschine derart angesteuert, dass die Brennkraftmaschine mit reduzierter Kompression mitgeschleppt wird. Dies wird insbesondere dadurch erreicht, dass während des gesamten stand-by-Betriebs mindestens ein Einlass- oder Auslassventil pro Zylinder geöffnet ist. Mit Vorteil bleiben die Einlassventile im Schleppmodus geschlossen und mehrere oder alle Auslassventile aller Zylinder während des gesamten stand-by-Betriebs geöffnet. Falls eine Überhitzung und damit eine Beschädigung von Bauteilen im Ansaugtrakt (durch das Verschieben des erhitzten Gasgemisches) nicht möglich ist bzw. sicher vermieden werden kann, können auch die Einlassventile zur Schleppmomentreduzierung geöffnet werden. Denkbar ist auch, dass zum Zwecke der Kompressionsminderung nicht bei jedem Zylinder mindestens ein Ventil geöffnet ist. Wesentlich ist lediglich, dass die Kompression während des Schleppbetriebs reduziert wird. In einer weiteren Ausgestaltung ist ebenfalls denkbar zur Kompressionsminderung sämtliche Ventile eines bzw. aller Zylinder geschlossen zu halten. Hierdurch wird im Saugtakt (Kolben bewegt sich von OT nach UT) der Brennkraftmaschine ein Vakuum erzeugt und im Ausstoß- bzw. Kompressionstakt (Kolben bewegt sich von UT nach OT) das erzeugte Vakuum wieder abgebaut. Um bevorzugt auch während des Schleppbetriebs eine möglichst konstante Drehzahl zu gewährleisten, arbeitet die elektrische Maschine bei geschlossenen Ventilen der Brennkraftmaschine zur Erzeugung des Vakuums im motorischen Betrieb und während des Abbaus des Vakuums im generatorischen Betrieb. Im generatorischen Betrieb stellt die elektrische Maschine somit eine entsprechende Last für die Brennkraftmaschine dar, die beim Abbau des Vakuums durch die saugende Wirkung ansonsten eine kurzzeitige Kolbenbeschleunigung (Drehzahlveränderung) zur Folge hätte.According to the invention Problem solved by the entirety of the features of claim 1. By the over ensured the electric machine Towing the internal combustion engine (during a so-called stand-by mode) is guaranteed that driven by the engine ancillaries at least in a partial operation (possibly with a reduced speed of the internal combustion engine) continue to operate. According to the invention is during the towing operation of the or each valve drive of the internal combustion engine so controlled that the internal combustion engine with reduced Compression is dragged along. This is achieved in particular by that while the entire stand-by operation at least one inlet or outlet valve open per cylinder is. Advantageously, the intake valves remain closed in towing mode and several or all exhaust valves of all cylinders during the entire stand-by operation open. If overheating and with it a damage of components in the intake tract (by moving the heated Gas mixture) not possible is or can be safely avoided, can also intake valves opened for drag torque reduction become. It is also conceivable that for the purpose of compression reduction not every cylinder has at least one valve open. It is only essential that the compression during towing is reduced. In a further embodiment is also conceivable for compression reduction all Keep valves of one or all cylinders closed. hereby is in the suction cycle (piston moves from OT to UT) of the internal combustion engine generates a vacuum and in the ejection or compression stroke (piston moves from UT to OT) the generated vacuum is degraded again. To prefer also during the Towing one as possible to ensure constant speed the electric machine works with the valves closed Internal combustion engine for generating the vacuum in engine operation and while the removal of the vacuum in regenerative operation. In generator mode Thus, the electric machine provides a corresponding load for the internal combustion engine Otherwise, when the vacuum is removed by the sucking effect a short-time piston acceleration (speed change) would result.
In einer bevorzugten Ausführung der Erfindung treibt die elektrische Maschine die Brennkraftmaschine in Abhängigkeit von der durch die mitgeschleppte Brennkraftmaschine generierten Verlustleistung an. Hierfür wird die durch die mitgeschleppte Brennkraftmaschine generierte Verlustleistung auf einen vordefinierten Grenzwert überwacht und die elektrische Maschine auf diese Sollgröße geregelt. Dabei ist der vordefinierte Grenzwert der Verlustleistung vorzugsweise veränderbar (z.B. in Abhängigkeit von dem Ladezustand der die elektrische Maschine versorgenden Energieeinheit).In a preferred embodiment According to the invention, the electric machine drives the internal combustion engine dependent on from the generated by the entrained internal combustion engine Power loss. Therefor is generated by the entrained internal combustion engine Power loss monitored to a predefined limit and the electric machine regulated to this target size. It is the predefined limit value of the power loss preferably changeable (e.g., depending on the state of charge of the power unit supplying the electric machine).
In einer weiteren Ausführung werden von der Brennkraftmaschine angetriebene Nebenaggregate vereinzelt in zeitlichen Abständen nach und nach oder gemeinsam nach Ablauf einer vordefinierten Zeitdauer oder bei Erreichen eines definierten Ladungszustandes (Ladezustandsschwelle) des elektrischen Energiespeichers von der mitgeschleppten Brennkraftmaschine abgekoppelt. Hierdurch wird – im Hinblick auf den oder die Energiespeicher zum Bereiben der elektrischen Maschine – ein optimiertes Energiemanagement erreicht.In another embodiment be driven by the internal combustion engine ancillaries singled at intervals gradually or together after expiration of a predefined period of time or upon reaching a defined state of charge (state of charge threshold) the electrical energy storage of the entrained internal combustion engine decoupled. This will - in With regard to the energy store (s) for rubbing the electrical power Machine on optimized energy management achieved.
Vorzugsweise werden die Nebenaggregate gemäß einer hinterlegten Tabelle abgeschaltet. Diese Tabelle kann dabei hierarchisch nach einer Fahrzyklen-Wahrscheinlichkeitsverteilung aufgebaut sein. Es können also Fahrzyklen überwacht und ausgewertet werden und in Abhängigkeit von über eine Vielzahl von Fahrzyklen gemittelten Parameterwerten (Fahrzeugbetriebsbedingungswerten) die Fahrzyklen-Wahrscheinlichkeitsverteilung verändert bzw. eine andere bereits hinterlegte Fahrzyklen-Wahrscheinlichkeitsverteilung ausgewählt werden.Preferably are the ancillaries according to a stored table switched off. This table can be hierarchical after a driving cycle probability distribution be constructed. It can thus monitoring driving cycles and evaluated and depending on a variety averaged parameter values of driving cycles (vehicle operating condition values) the driving cycle probability distribution changed or another already stored driving-cycle probability distribution selected become.
Im
Folgenden wird die Erfindung anhand einer Figur näher erläutert. Die
einzige Figur zeigt die schematische Darstellung eines Antriebsstranges
eines Kraftfahrzeugs, umfassend eine Brennkraftmaschine
Fahrzeugbetriebsbedingungen im Sinne der Erfindung sind Informationen über Zustände des Fahrzeugs selbst, wie beispielsweise: Motordrehzahl, erzeugtes Drehmoment (z.B. an der Motorabtriebswelle), Geschwindigkeit, Standzeit, Schmiermitteltemperatur, Kühlmitteltemperatur, Ladezustand der Batterie, Erkennung ob und wie lange eine Bremse aktiviert wurde, usw.). Fahrzeugumgebungsbedingungen im Sinne der Erfindung sind Informationen über Zustände der Fahrzeugumgebung, wie beispielsweise: Sichtverhältnisse – Nebel vorhanden?, Anzeigezustand einer Signalanlage, Abstand zum vorausfahrenden Fahrzeug, usw..Vehicle operating conditions Within the meaning of the invention, information about states of the vehicle itself, such as For example: engine speed, generated torque (e.g., at the Engine output shaft), speed, service life, lubricant temperature, Coolant temperature, State of charge of the battery, detection of whether and how long a brake has been activated, etc.). Vehicle environment conditions in the sense of Invention are information about conditions the vehicle environment, such as: visibility - fog available ?, display status of a signal system, distance to the preceding vehicle Vehicle, etc ..
Nach welchen Regeln (d.h. in Abhängigkeit von welchen Fahrzeugbetriebsbedingungen und/oder Fahrzeugumgebungsbedingungen) die Brennkraftmaschine eines Kraftfahrzeugs innerhalb eines Fahrzyklus sinnvollerweise vorübergehend abgeschaltet wird, ist bereits vielfach bekannt (sogenannte Motor-Stop-Start-Automatik) und nicht Gegenstand dieser Erfindung. Für das erfindungsgemäße Verfahren werden Bedingungen ausgewählt und ausgewertet, aufgrund deren Vorliegen auf einen Zustand geschlossen werden kann, in dem ein aktiver Betrieb der Brennkraftmaschine zum Zwecke des Fahrbetriebs nicht erforderlich ist. Für die Realisierung des erfindungsgemäßen Verfahrens wird bevorzugt auf herkömmliche Auswerteverfahren, wie sie bei bekannten Motor-Stop-Start-Automatiken Verwendung finden zurückgegriffen – es kann das bei diesen Verfahren erzeugte Motor-Stop-Signal als übergeordnete Fahrzeugbetriebsbedingung als Initiierung für eine Überführung vom Normalbetrieb der Brennkraftmaschine in den Schleppbetrieb derselben benutzt werden.To which rules (i.e., depending on which vehicle operating conditions and / or vehicle environment conditions) the internal combustion engine of a motor vehicle within a driving cycle reasonably temporary is switched off, is already widely known (so-called engine stop-start automatic) and not the subject of this invention. For the inventive method conditions are selected and evaluated, due to their presence closed on a condition can be, in which an active operation of the internal combustion engine for Purpose of driving is not required. For the realization the method according to the invention is preferred to conventional Evaluation methods, as used in known engine stop-start automatic systems find recourse - it can the motor stop signal generated in these methods as a higher-level Vehicle operating condition as initiation for a transfer from normal operation of the internal combustion engine be used in the towing of the same.

Das erfindungsgemäße Verfahren ist für Brennkraftmaschinen geeignet, bei denen eine gesteuerte Veränderung von Ventilsteuerzeiten (variabel steuerbare Ventilantriebe) realisierbar ist.The inventive method is for internal combustion engines suitable in which a controlled change of valve timing (variably controllable valve actuators) can be realized.
Bevorzugt findet die Erfindung Anwendung bei hydraulisch oder elektromagnetisch (EVT: elektromagnetischer Ventilantrieb) betriebenen voll variabel steuerbaren Ventilantrieben (d.h.: Einzel- oder Gruppen-Ventilantriebe ohne eine gemeinsame Nockenwelle für alle Einlassventile und eine gemeinsame Nockenwelle für alle Auslassventile).Prefers finds the invention application in hydraulic or electromagnetic (EVT: electromagnetic valve actuator) operated fully variable controllable valve actuators (ie: single or group valve actuators without a common camshaft for all intake valves and one common camshaft for all exhaust valves).
Geeignet für das erfindungsgemäße Verfahren sind allerdings auch alle anderen Brennkraftmaschinen mit variabel steuerbarem Ventilantrieb über eine Nockenwelle, bei denen die Nockenwelle zumindest im Hub verstellbar ausgebildet ist. Bei Brennkraftmaschinen mit im Hub verstellbaren Nockenwellen wird zur Erreichung der Schleppmomentreduzierung im Schleppbetrieb vorzugsweise die Nockenwelle in eine Position überführt in der alle Ventile jedes Zylinders ständig geschlossen sind und die jeweilige Nockenwelle somit quasi lastfrei betrieben wird. Hierdurch wird zum Einen, wie bereits zuvor beschrieben, eine Verringerung der Kompression der Brennkraftmaschine erreicht und zum Anderen das Schleppmoment dadurch reduziert, dass die Nockenwellen lastfrei arbeiten (mit den Ventilen nicht mehr in Eingriff stehen).However, all other internal combustion engines are also suitable for the process according to the invention Machines with variably controllable valve drive via a camshaft, in which the camshaft is designed to be adjustable at least in the stroke. In internal combustion engines with camshafts which are adjustable in stroke, the camshaft is preferably transferred to a position in which all valves of each cylinder are constantly closed in order to achieve the reduction in drag torque during towing, and the respective camshaft is thus operated virtually without load. As a result, on the one hand, as already described above, a reduction of the compression of the internal combustion engine is achieved and on the other hand the drag torque is reduced by the fact that the camshafts work without load (are no longer in engagement with the valves).
