Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Steuern einer Klimaanlage für einen Fahrgastinnenraum eines Kraftfahrzeugs.The The invention relates to an apparatus and a method for controlling an air conditioner for a passenger compartment of a motor vehicle.
Die
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung sowie ein Verfahren zum Steuern einer Klimaanlage für einen Fahrgastinnenraum eines Kraftfahrzeugs zu schaffen, welche eine weitere Reduzierung des Kraftstoffverbrauchs des Verbrennungsmotors ermöglicht.task The present invention is an apparatus and a method for controlling an air conditioner for a passenger compartment of a motor vehicle to create a further reduction the fuel consumption of the internal combustion engine allows.
Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung sowie ein Verfahren zum Steuern einer Klimaanlage für einen Fahrgastinnenraum eines Kraftfahrzeugs gemäß Patentanspruch 1 bzw. Patentanspruch 8 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den jeweiligen Unteransprüchen angegeben, wobei vorteilhafte Ausgestaltungen der Vorrichtung – soweit anwendbar – als vorteilhafte Ausgestaltungen des Verfahrens und umgekehrt anzusehen sind.The The object is achieved by a device and a method for controlling an air conditioner for a Passenger compartment of a motor vehicle according to claim 1 or claim 8 solved. Advantageous embodiments with appropriate and non-trivial further education of the Invention are specified in the respective subclaims, wherein advantageous embodiments of the device - so far applicable - as advantageous embodiments of the method and vice versa.
Eine Vorrichtung zum Steuern einer Klimaanlage für einen Fahrgastinnenraum eines Kraftfahrzeugs, welche eine weitere Reduzierung des Kraftstoffverbrauchs des Verbrennungsmotors ermöglicht, umfasst erfindungsgemäß eine Klimaanlagensteuereinrichtung (KLA) und eine Motorsteuereinrichtung (MSG), insbesondere eine Start-Stop-Automatik, mittels welcher ein Betriebszustand des Verbrennungsmotors des Kraftfahrzeugs zu steuern ist, wobei die KLA und die MSG zum Austauschen eines den Betriebszustand charakterisierenden Parameterwerts miteinander gekoppelt sind und wobei die KLA ausgelegt ist, einen in den Fahrgastinnenraum zu transportierenden Luftmassenstrom in Abhängigkeit des den Betriebszustand charakterisierenden Parameterwerts zu steuern. Auf diese Weise kann der Luftmassenstrom im Gegensatz zum Stand der Technik in Abhängigkeit des Betriebszustands des Verbrennungsmotors gesteuert werden, wodurch entsprechende Verbrauchsvorteile erzielt werden. Dabei ist es unerheblich, ob das Kraftfahrzeug nur über einen Verbrennungsmotor verfügt und die MSG des Kraftfahrzeugs als einfache Start-Stopp-Automatik ausgebildet ist, oder ob es sich bei dem Kraftfahrzeug um ein Micro-, Mild- oder Full-Hybridfahrzeug mit zusätzlichem Elektromotor handelt.A Device for controlling an air conditioning system for a passenger compartment a motor vehicle, which further reduces fuel consumption of the internal combustion engine, according to the invention comprises a Air conditioning control device (KLA) and a motor control device (MSG), in particular a start-stop system, by means of which an operating state is to control the internal combustion engine of the motor vehicle, wherein the KLA and the MSG for exchanging a state of operation characterizing Parameter value are coupled together and where the KLA designed is, to be transported in the passenger compartment air mass flow depending on the operating condition characterizing Control parameter value. In this way, the air mass flow in contrast to the prior art depending on Operating state of the internal combustion engine are controlled, thereby appropriate consumption benefits can be achieved. It is irrelevant whether the motor vehicle only has an internal combustion engine and the MSG of the motor vehicle as a simple start-stop system is formed, or whether the motor vehicle is a micro, Mild or full hybrid vehicle with additional electric motor is.
In einer vorteilhaften Ausgestaltung der Erfindung hat es sich als vorteilhaft gezeigt, dass die MSG ausgelegt ist, einen einen Stopp-Zustand und/oder einen prognostizierten Stopp-Zustand und/oder einen Betriebs-Zustand des Verbrennungsmotors charakterisierenden Parameterwert an die KLA zu übermitteln. Dadurch kann beispielsweise bei laufendem Verbrennungsmotor ein größerer Luftmassenstrom, bei gestopptem Verbrennungsmotor hingegen ein verringerter Luftmassenstrom in den Fahrgastinnenraum geleitet werden, wodurch eine entsprechend langsamere Veränderung der Temperatur des Fahrgastinnenraums sichergestellt wird. Dies ermöglicht in der Folge einen verlängerten Stopp-Zustand des Verbrennungsmotors und damit eine weitere Senkung seines Kraftstoffverbrauchs. Besondere Vorteile werden dabei insbesondere dann erzielt, wenn die MSG einen prognostizierten Stopp-Zustand an die KLA übermittelt, da der Luftmassenstrom auf diese Weise bereits vor dem Stopp des Verbrennungsmotors reduziert werden kann, wodurch eine weitere Reduzierung des Kraftstoffverbrauchs gegeben ist.In an advantageous embodiment of the invention, it has as Advantageously shown that the MSG is designed to have a stop state and / or a predicted stop state and / or an operating state of the internal combustion engine characterizing parameter value to the KLA to convey. This can, for example, while running Internal combustion engine a larger mass air flow, When the internal combustion engine is stopped, however, a reduced air mass flow be directed into the passenger compartment, creating a corresponding slower change in the temperature of the passenger compartment is ensured. This allows one in the sequence extended stop state of the internal combustion engine and thus a further reduction of its fuel consumption. Special advantages This is achieved in particular when the MSG has a predicted stop state transmitted to the KLA, as the air mass flow on this Way already be reduced before the stop of the engine can, thereby further reducing fuel consumption given is.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass mittels der KLA eine Umluftklappe der Klimaanlage in Abhängigkeit des Parameterwerts in eine mit diesem korrespondierende Stellung zu bewegen ist. Somit kann die Umluftklappe beispielsweise bei einem Stopp bzw. einem prognostizierten Stopp des Verbrennungsmotors in eine vollständige Umluftstellung bewegt werden, wodurch kein Luftmassenstrom mehr in den Fahrgastinnenraum transportiert wird und der Stopp-Zustand des Verbrennungsmotors entsprechend länger aufrecht erhalten werden kann. Umgekehrt kann die Umluftklappe während des Betriebs-Zustands des Verbrennungsmotor beispielsweise in eine manuell oder automatisch vorgebbare Position bewegt werden.In a further advantageous embodiment of the invention is provided that by means of the KLA a recirculation door of the air conditioner depending on Parameter value in a corresponding with this position is moving. Thus, the recirculation damper, for example, at a Stop or a predicted stop of the internal combustion engine in a full recirculation position to be moved, thereby no air mass flow transported more into the passenger compartment and the stop state of the internal combustion engine correspondingly longer can be maintained. Conversely, the recirculation damper during the operating state of the internal combustion engine, for example, in a be moved manually or automatically predetermined position.
Weiterhin hat es sich als vorteilhaft gezeigt, dass mittels der KLA eine Gebläseeinrichtung der Klimaanlage in Abhängigkeit des Parameterwerts zu steuern ist, wobei die Gebläseeinrichtung zum Transportieren des Luftmassenstroms in den Fahrgastinnenraum ausgebildet ist. Durch Steuerung einer derartigen Gebläseeinrichtung kann vorteilhaft Einfluss auf den von Außen in den Fahrgastinnenraum zu transportierenden Luftmassenstrom und damit auf die Temperatur innerhalb des Fahrgastinnenraums genommen werden. So kann beispielsweise bei einem Stopp bzw. einem prognostizierten Stopp des Verbrennungsmotors die Leistung der Gebläseeinrichtung reduziert und der transportierte Luftmassenstrom entsprechend verringert werden. Dadurch kann auch die Dauer des Stopp-Zustands des Verbrennungsmotors länger aufrecht erhalten werden, wodurch eine weitere Verringerung des Kraftstoffverbrauchs gegeben ist.Furthermore, it has been found to be advantageous that by means of the KLA a blower of the Kli maanlage depending on the parameter value is to be controlled, wherein the blower device is designed for transporting the air mass flow in the passenger compartment. By controlling such a blower device can be advantageously taken advantage of the air mass flow to be transported from the outside into the passenger compartment and thus to the temperature inside the passenger compartment. Thus, for example, in the case of a stop or a predicted stop of the internal combustion engine, the power of the fan device can be reduced and the transported air mass flow can be correspondingly reduced. Thereby, the duration of the stop state of the internal combustion engine can be maintained longer, whereby a further reduction in fuel consumption is given.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die KLA mit einem Temperatursensor koppelbar ist und ausgelegt ist, den Luftmassenstrom unter zusätzlicher Berücksichtigung eines eine Temperatur, insbesondere eine Außentemperatur des Kraftfahrzeugs, charakterisierenden Parameterwerts zu steuern. Dies erlaubt eine besonders exakte Berücksichtigung der momentanen Temperaturwerte, welche im Bereich der Klimaanlage bzw. des Kraftfahrzeugs vorherrschen. Somit kann die Temperatur des Luftmassenstroms bei der Steuerung der Klimaanlage zusätzlich berücksichtigt werden.In a further advantageous embodiment of the invention is provided that the KLA can be coupled to a temperature sensor and is designed to the air mass flow with additional consideration one is a temperature, in particular an outside temperature of the motor vehicle, characterizing parameter value. This allows a particularly accurate consideration of current temperature values, which in the area of the air conditioner or of the motor vehicle prevail. Thus, the temperature of the air mass flow be considered additionally in the control of the air conditioning.
Eine Steigerung des Klimatisierungskomforts für Insassen des Kraftfahrzeugs ist dadurch ermöglicht, dass die KLA mit einem Luftgütesensor koppelbar ist und ausgelegt ist, den Luftmassenstrom unter zusätzlicher Berücksichtigung eines eine Luftgüte des Fahrgastinnenraums charakterisierenden Parameterwerts zu steuern.A Increase of the air conditioning comfort for inmates of the Motor vehicle is thereby enabled that the KLA with an air quality sensor is coupled and is designed to the Air mass flow with additional consideration of an air quality of the passenger compartment characterizing Control parameter value.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die MSG mit einem Zeitgeber koppelbar ist und ausgelegt ist, den Verbrennungsmotor in Abhängigkeit eines Zeitwerts zu steuern. Durch Einbeziehen eines derartigen Zeitwerts kann beispielsweise eine Änderung des Betriebszustands des Verbrennungsmotors nur dann erlaubt werden, wenn eine vorgegebene Sperrzeit überschritten wurde. Dadurch wird ein permanentes An- und Abschalten des Verbrennungsmotors unterbunden, wodurch neben einer Komfortsteigerung für die Fahrzeuginsassen auch eine erhebliche Verschleißminderung des Verbrennungsmotors sichergestellt ist.In a further advantageous embodiment of the invention is provided that the MSG is couplable with a timer and is designed to the internal combustion engine in dependence of a time value Taxes. By including such a time value, for example a change in the operating state of the internal combustion engine only be allowed if a given blocking time has been exceeded has been. This will be a permanent on and off of the engine prevented, which in addition to an increase in comfort for the Vehicle occupants also a significant reduction in wear of the internal combustion engine is ensured.
Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zum Steuern einer Klimaanlage für einen Fahrgastinnenraum eines Kraftfahrzeugs, mit einer Klimaanlagensteuereinrichtung (KLA) und einer Motorsteuereinrichtung (MSG), insbesondere einer Start-Stop-Automatik, mittels welcher ein Betriebszustand eines Verbrennungsmotors des Kraftfahrzeugs zu steuern ist, wobei die KLA und die MSG zum Austauschen eines den Betriebszustand charakterisierenden Parameterwerts miteinander gekoppelt sind, mit den Schritten a) Ermitteln des den Betriebszustand des Verbrennungsmotors charakterisierenden Parameterwerts mittels der MSG, b) Übermitteln des Parameterwerts an die KLA und c) Steuern eines in den Fahrgastinnenraum zu transportierenden Luftmassenstroms in Abhängigkeit des Parameterwerts mittels der KLA. Durch Berücksichtigung des den Betriebszustand des Verbrennungsmotors charakterisierenden Parameterwerts wird eine verbesserte Steuerung des in den Fahrgastinnenraum zu transportierenden Luftmassenstroms ermöglicht. Damit kann die Dauer eines Stopp-Zustands des Verbrennungsmotors verlängert und der Kraftstoffverbrauch des Verbrennungsmotors entsprechend reduziert werden. Weitere erzielbare Vorteile sind aus den vorhergehenden Beschreibungen zu entnehmen.One Another aspect of the invention relates to a method for controlling an air conditioning system for a passenger compartment of a motor vehicle, with an air conditioning control device (KLA) and a motor control device (MSG), in particular a start-stop system, by means of which an operating condition of an internal combustion engine of the motor vehicle control, with the KLA and the MSG exchanging a Operating state characterizing parameter value coupled together are, with the steps a) determining the operating condition of the Internal combustion engine characterizing parameter value by means of MSG, b) transmitting the parameter value to the KLA and c) Controlling an air mass flow to be transported into the passenger compartment depending on the parameter value by means of the KLA. By Consideration of the operating condition of the internal combustion engine characterizing parameter value becomes improved control of the air mass flow to be transported in the passenger compartment allows. Thus, the duration of a stop state of the Extended combustion engine and fuel economy of the Internal combustion engine can be reduced accordingly. More achievable Advantages can be taken from the previous descriptions.
In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass in Schritt c) eine Umluftklappe der Klimaanlage in eine vorgegebene Stellung bewegt wird, wenn in Schritt a) ein einen Betriebs-Zustand des Verbrennungsmotors charakterisierender Parameterwert ermittelt wird. Dies ermöglicht eine einfache und situationsabhängige Steuerung des in den Fahrgastinnenraum zu transportierenden Luftmassenstroms. Dabei hat es sich insbesondere als vorteilhaft gezeigt, dass in Schritt c) die Umluftklappe der Klimaanlage geschlossen wird, wenn in Schritt a) ein einen Stopp-Zustand und/oder einen prognostizierten Stopp-Zustand des Verbrennungsmotors charakterisierender Parameterwert ermittelt wird. Auf diese Weise kann das Transportieren zu warmer Luft in den Fahrgastinnenraum zuverlässig unterbunden und der Stopp-Zustand des Verbrennungsmotors entsprechend verlängert werden. Ein Schließen der Umluftklappe bereits bei einem prognostizierten Stopp-Zustand des Verbrennungsmotors ermöglicht zudem eine deutliche Erhöhung des Komforts der Fahrzeuginsassen, da die mit dem Schließen verbundene Geräuschänderung bei noch bewegtem Kraftfahrzeug weniger auffällt.In an advantageous embodiment of the invention is provided that in step c) a recirculation damper of the air conditioning in a predetermined Position is moved when in step a) an operating state of the internal combustion engine characterizing parameter value determined becomes. This allows a simple and situation-dependent Control of the air mass flow to be transported in the passenger compartment. It has been shown to be particularly advantageous that in Step c) the recirculation damper of the air conditioner is closed when in step a) a stop state and / or a predicted one Stop state of the internal combustion engine characterizing parameter value is determined. In this way, the transport can be too warm Air in the passenger compartment reliably prevented and the stop state of the engine extended accordingly become. A closing of the recirculation damper already at a predicted Stop state of the internal combustion engine also allows a significant increase in the comfort of the vehicle occupants, since the noise change associated with closing less noticeable when the vehicle is still moving.
Um ein permanentes Stoppen und Starten des Verbrennungsmotors in bestimmten Fahrsituationen und damit unerwünschte Komforteinbussen für die Fahrzeuginsassen sowie einen entsprechend erhöhten Verschleiß zu verhindern, ist vorgesehen dass in Schritt c) die Umluftklappe der Klimaanlage nur dann geschlossen wird, wenn zusätzlich eine vorbestimmte Motor-Stopp-Sperrzeit überschritten wird.Around a permanent stopping and starting of the internal combustion engine in certain Driving situations and thus undesirable comfort losses for the vehicle occupants and a correspondingly increased To prevent wear, it is provided that in step c) the recirculation damper of the air conditioner is only closed when additionally exceeded a predetermined motor stop blocking time becomes.
Wird das Kraftfahrzeug bei einer Außentemperaturen bewegt, welche unterhalb eines vorgegebenen Grenzwerts liegt, hat es sich als vorteilhaft gezeigt, dass in Schritt c) die Umluftklappe der Klimaanlage nicht geschlossen wird, da ein Schließen der Umluftklappe in diesem Fall eine unnötige Erwärmung des Fahrgastinnenraums und somit eine unerwünschte Verkürzung des Stopp-Zustands des Verbrennungsmotors verursachen würde.If the motor vehicle is moved at an outside temperature which is below a predetermined limit value, it has proved to be advantageous that in step c) the recirculation damper of the air conditioning system Position is not closed, since closing the recirculation damper in this case would cause unnecessary heating of the passenger compartment and thus an undesirable shortening of the stop state of the engine.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass in Schritt c) eine Förderleistung einer den Luftmassenstrom in den Fahrgastinnenraum transportierenden Gebläseeinrichtung der Klimaanlage um einen vorbestimmten Faktor reduziert wird, wenn in Schritt a) ein einen Stopp-Zustand und/oder einen prognostizierten Stopp-Zustand des Verbrennungsmotors charakterisierender Parameterwert ermittelt wird. Eine Reduzierung der Förderleistung der Gebläseeinrichtung stellt dabei eine konstruktiv einfache Möglichkeit dar, die Temperatur im Fahrgastinnenraum über eine möglichst lange Zeitdauer zumindest annähernd konstant zu halten und den Stopp-Zustand des Verbrennungsmotors entsprechend zu verlängern.In a further advantageous embodiment of the invention is provided that in step c) a delivery rate of the air mass flow in the passenger compartment transporting blower device the air conditioner is reduced by a predetermined factor, if in step a), a stop state and / or a predicted stop state of the internal combustion engine characterizing parameter value determined becomes. A reduction in the delivery rate of the blower device provides This is a structurally simple way, the temperature in the passenger compartment over as long as possible To keep duration at least approximately constant and the Extend stop state of the internal combustion engine accordingly.
Dabei wir ein möglichst hoher Insassenkomfort dadurch sichergestellt, dass in Schritt c) die Förderleistung der Gebläseeinrichtung auf einen vorgebbaren Wert eingestellt wird, wenn in Schritt a) ein einen Betriebs-Zustand des Verbrennungsmotors charakterisierender Parameterwert ermittelt wird. Der Wert kann dabei beispielsweise manuell oder über eine automatische Klimaanlagensteuerung als Soll-Wert vorgegeben werden. In diesem Zusammenhang hat es sich weiterhin als vorteilhaft gezeigt, dass in Schritt c) die Förderleistung der Gebläseeinrichtung schrittweise auf den vorgebbaren Wert eingestellt wird, wenn die Leistung zuvor um den vorbestimmten Faktor reduziert war. Mit anderen Worten wird die Förderleistung der Gebläseeinrichtung nach einem Starten des Verbrennungsmotors vom reduzierten Ist-Wert schrittweise über eine Rampe auf den manuell oder automatisch vorgegebenen Soll-Wert erhöht, wodurch ein erhöhter Insassenkomfort sichergestellt wird.there we ensure the highest possible occupant comfort, that in step c) the delivery rate of the blower device is set to a predefinable value, if in step a) an operating condition of the internal combustion engine characterizing Parameter value is determined. The value can be, for example manually or via an automatic air conditioning control be specified as a target value. In this context, it has furthermore shown to be advantageous that in step c) the delivery rate the blower device gradually to the predetermined Value is set if the power previously by the predetermined Factor was reduced. In other words, the delivery rate the blower device after starting the internal combustion engine from the reduced actual value gradually over a ramp on the increased manually or automatically preset target value, whereby an increased occupant comfort is ensured.
