Abstract
Description
Die Erfindung betrifft ein Verfahren zur Regelung einer Kraftfahrzeug-Klimaanlage der im Oberbegriff des Patentanspruch 1 angegebenen Art sowie eine Kraftfahrzeug-Klimaanlage zum Betrieb mit einem solchen Verfahren.The The invention relates to a method for controlling a motor vehicle air conditioning system specified in the preamble of claim 1 and a kind Automotive air conditioning system for operation with such a method.

Als nachteilig bei diesem Verfahren ist anzusehen, dass durch das Regelungsverfahren der Kraftfahrzeug-Klimaanlage die bei Stillstand des Kältemittelkreislaufs erzielbare Kühlwirkung des Kältespeichers zeitlich stark begrenzt ist.When A disadvantage of this method is to be considered that by the regulatory procedure the motor vehicle air conditioning at standstill of the refrigerant circuit achievable cooling effect of the cold storage time is very limited.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zur Regelung einer Kraftfahrzeug-Klimaanlage sowie eine solche Anlage der eingangs genannten Art anzugeben, durch welches die Kühlwirkung eines Kältespeichers verbessert wird.task The present invention is a method for controlling a Motor vehicle air conditioning and such a system of the beginning specify the type mentioned by which the cooling effect a cold storage is improved.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 und durch eine Kraftfahrzeug-Klimaanlage mit den Merkmalen des Patentanspruchs 3 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den jeweils abhängigen Patentansprüchen angegeben.These The object is achieved by a method with the features of claim 1 and by a motor vehicle air conditioning with the features of claim 3 solved. advantageous Embodiments with expedient developments The invention are in the respective dependent claims specified.
Bei dem erfindungsgemäßen Verfahren zur Regelung einer Kraftfahrzeug-Klimaanlage ist vorgesehen, dass die Verdampfungstemperatur eines Kältemittels im Verdampfer in einem Zeitabstand vor einem Stopp eines Kältemittelkreislaufs abgesenkt wird. Dadurch ist es möglich, ein Kältespeichermedium sehr stark abzukühlen und so die Dauer der Kühlwirkung eines Kältespeichers bei Stopp des Kraftfahrzeugmotors und des Kältemittelkreislaufs zu verlängern. Dies führt zu einer deutlichen Steigerung des Klimakomforts für die Fahrzeuginsassen, während gleichzeitig das Kraftstoff-Einsparpotenzial der Motorstopp-Funktion genutzt wird.at the inventive method for controlling a Automotive air conditioning is provided that the evaporation temperature a refrigerant in the evaporator at a time interval before is lowered to a stop of a refrigerant circuit. This makes it possible to use a cold storage medium very cool and so the duration of the cooling effect a cold storage at stop of the vehicle engine and the refrigerant circuit to extend. This leads to a significant increase in climate comfort for the vehicle occupants while at the same time used the fuel-saving potential of the engine stop function becomes.
Das Verfahren eignet sich insbesondere für Klimaanlagen in Fahrzeugen, die über eine Start-Stopp-Funktion bzw. einen Leerlauf-Stopp Betriebsmodus verfügen, wie beispielsweise Hybrid-Fahrzeuge. Hierbei wird der Fahrzeugmotor bei kurzzeitigem Fahrzeugstillstand, zum Beispiel beim Halten an einer Ampel, im Stau oder im Leerlauf, automatisch abgeschaltet um den Kraftstoffverbrauch und Emissionen zu reduzieren. Mit dem Stopp des Fahrzeugmotors wird auch der Kompressor der Klimaanlage außer Betrieb genommen und der Kältemittelkreislauf kommt zum Stillstand.The Method is particularly suitable for air conditioners in Vehicles that have a start-stop function or a Idle stop operating mode, such as Hybrid vehicles. Here, the vehicle engine is short-term Vehicle standstill, for example when stopping at a traffic light, in Congestion or idle, automatically shut off for fuel consumption and Reduce emissions. With the stop of the vehicle engine is also the compressor of the air conditioning system taken out of service and the refrigerant circuit comes to a standstill.
In einer besonders vorteilhaften Ausgestaltung der Erfindung wird der Zeitabstand vor dem Stopp des Kältemittelkreislaufs mit Hilfe eines Navigationssystems ermittelt. Hierdurch können auf besonders geeignete Weise Motor-Leerlauf-Situationen wie beispielsweise durch Staus und/oder Ampeln bedingte Fahrzeugstopps vorhergesehen und bei der Regelung der Klimaanlage berücksichtigt werden.In a particularly advantageous embodiment of the invention is the Time interval before the refrigerant circuit stops with Help of a navigation system determined. This allows in a particularly suitable manner engine idling situations such as foreseen vehicle stops due to traffic jams and / or traffic lights and be taken into account in the regulation of the air conditioning.
Die im Zusammenhang mit dem erfindungsgemäßen Verfahren beschriebenen bevorzugten Ausführungsformen und Vorteile gelten, soweit anwendbar, auch für eine erfindungsgemäß betriebene Kraftfahrzeug-Klimaanlage.The in connection with the method according to the invention described preferred embodiments and advantages apply, as applicable, also for a motor vehicle air conditioning system operated according to the invention.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnungen.Further Advantages, features and details of the invention will become apparent the following description of a preferred embodiment as well as from the drawings.
