Abstract
Description
Die Erfindung betrifft ein Verfahren zur Steuerung einer Heiz- und Belüftungsvorrichtung mit den Merkmalen des Patentanspruchs 1.The invention relates to a method for controlling a heating and ventilation device having the features of patent claim 1.
In Kraftfahrzeugen mit herkömmlichen Verbrennungsmotoren werden in der Regel nur bei sommerlichen Lastfällen der Belüftung hohe Umluftanteile angesteuert. Dabei kann aufgrund der Ansaugung bereits gekühlter Innenraumluft, der Energieverbrauch, der zur Bereitstellung dieser Kälteenergie notwendig gewesen wäre, eingespart und die notwendige Kompressorlast reduziert werden. Da bei konventionellen Antrieben genügend Motorabwärme vorhanden ist, um kalte Frischluft zu erwärmen, bestand bisher keine Notwendigkeit den energieeffizienten Umluftbetrieb auf winterliche Lastfälle zu erweitern. Zudem besteht dabei ein erhebliches Risiko der Beschlagsbildung an kalten Scheibenflächen. Für Elektrofahrzeug ohne nennenswerte Motorabwärme besitzt ein Umluftbetrieb oder Teilumluftbetrieb bei winterlichen Lastfällen ein hohes Energieeinsparpotential und damit eine erhebliche Reichweitenverbesserung. Sogar bei konventionellen Antrieben ist ein Umluftbetrieb für winterliche Lastfälle ebenfalls wünschenswert, da dadurch eine schnellere Aufheizung der Kabine erfolgen kann und Zuheizsysteme speziell bei wirkungsgradoptimierten Motoren entfallen könnten.In motor vehicles with conventional internal combustion engines high ventilation rates are usually controlled only in summer load cases of ventilation. In this case, due to the intake of already cooled indoor air, the energy consumption that would have been necessary to provide this cooling energy, saved and the necessary compressor load can be reduced. Since there is sufficient engine waste heat in conventional drives to heat cold fresh air, there was no need to expand the energy-efficient recirculation mode for winter load cases. In addition, there is a considerable risk of fogging on cold disc surfaces. For electric vehicles without significant engine waste heat has a recirculation mode or partial recirculation mode in winter load cases, a high energy saving potential and thus a considerable range improvement. Even in conventional drives recirculation mode for winter load cases is also desirable because this can be done faster heating of the cabin and Zuheizsysteme could be omitted especially in efficiency-optimized engines.
Somit beschäftigt sich die Erfindung mit der Aufgabe, eine Steuerung einer Heiz- und Belüftungsvorrichtung zu schaffen, die zur Steigerung der Effizienz weitergehende Umluftbetriebsfälle vorsieht.Thus, the invention has the object to provide a control of a heating and ventilation device, which provides for increasing the efficiency of further Umluftbetriebsfälle.
Die Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst. Bei einem solchen Verfahren wird der beschlagfrei betreibbare Umluftanteil dadurch erhöht, dass Scheiben des Fahrzeugs elektrisch beheizt werden, wobei ein Steuergerät den Umluftanteil einerseits und die elektrische Leistung für die Scheibenheizung andererseits so einregelt, dass eine maximale Energieeffizienz bei gleichzeitig beschlagfreien Scheiben erreicht wird.The object is achieved by a method having the features of patent claim 1. In such a method, the fog-free operable recirculated air is increased by the fact that the windows of the vehicle are heated electrically, with a control unit on the one hand and the electric power for the window heating on the other hand so adjusted that maximum energy efficiency is achieved at the same time fog-free discs.
Bei einer vorteilhaften Ausgestaltung des Verfahrens wird beim Start des Verfahrens mindestens ein Fahrzeug- und/oder Umgebungsparameter gemessen und abhängig von diesem Parameter eine Starteinstellung des Umluftanteils und der Heizleistung der Scheibenheizung eingestellt. Dadurch kann eine besonders schnelle Einregelung der einzustellenden Größen auf Energieeffizienz und Klimakomfort erreicht werden.In an advantageous embodiment of the method, at least one vehicle and / or environmental parameter is measured at the start of the method and, depending on this parameter, a start setting of the recirculated-air portion and the heating power of the window heater is set. As a result, particularly rapid adjustment of the parameters to be set to energy efficiency and climate comfort can be achieved.
Um eine mindeste Luftgüte beizubehalten, wird bei einer vorteilhaften Ausführung des Verfahrens der Umluftanteil auf einen Maximalwert mit minimalem Frischluftanteil, beispielsweise einem minimalen Frischluftanteil von 15% beschränkt, so dass die Zufuhr eines geringen Anteils an Frischluft gesichert ist.In order to maintain a minimum air quality, in an advantageous embodiment of the method, the circulated air fraction is limited to a maximum value with a minimum fresh air fraction, for example a minimum fresh air content of 15%, so that the supply of a small proportion of fresh air is ensured.
Eine Ausführung des Verfahrens weist eine Begrenzung der Heizleistung der Scheibenheizung auf einen maximalen Leistungswert auf, so dass vorteilhafterweise Komfortkriterien, wie beispielsweise ein kühler Kopfraum, eingehalten werden können. Dabei kann die Begrenzung in Abhängigkeit von gemessenen Parametern, wie beispielsweise der Außentemperatur oder einer Belüftungstemperatur erfolgen.An embodiment of the method has a limitation of the heating power of the window heating to a maximum power value, so that advantageously comfort criteria, such as a cool headspace, can be maintained. In this case, the limitation can be carried out as a function of measured parameters, such as, for example, the outside temperature or an aeration temperature.
Um vorteilhafterweise ein noch effizienteres und stärker Komfort orientiertes Verfahren zu ermöglichen, wird bei einer Ausgestaltung neben der Einstellung der Leistung der Scheibenheizung und des Umluftanteils eine Einstellung eines Luftstromes vorgenommen. Dabei kann es sich um den Gesamtluftstrom oder auch einen Teilluftstrom handeln. Wird beispielsweise der Luftstrom über die Entfrosterdüse eingestellt, kann dieser bei höherer Leistung der Scheibenheizung reduziert werden, so dass mehr aufgewärmte Luft dem restlichen Innenraum zugeführt und die Kabine somit schneller aufgeheizt werden kann.In order to advantageously enable an even more efficient and more comfort-oriented method, an adjustment of an air flow is made in one embodiment in addition to the adjustment of the power of the window heater and the recirculating air. This may be the total air flow or a partial air flow. For example, if the air flow through the defroster, it can be reduced with higher performance of the window heating, so that more heated air supplied to the rest of the interior and the cabin can thus be heated faster.
Bei einer Ausführung des Verfahrens wird neben der Einstellung der Leistung der Scheibenheizung und des Umluftanteils eine Einstellung einer Heizleistung zum Aufheizen des Zuluftstromes eingestellt. Dadurch ist der Vorteil zu erreichen, dass das Verfahren noch effizienter durchgeführt und der Energieaufwand weiter reduziert werden kann.In one embodiment of the method, an adjustment of a heating power for heating the supply air flow is set in addition to the adjustment of the power of the window heater and the recirculating air. This has the advantage that the process can be carried out even more efficiently and the energy consumption can be further reduced.
Um eine weitere vorteilhafte Ausgestaltung des Verfahrens bereitzustellen, wird ein Kennfeld, das bei Systemstart parameterabhängig Startwerte für die einzustellenden Größen vorgibt, verändert. So können diese Startwerte durch ein selbstlernendes System ständig verbessert werden.In order to provide a further advantageous embodiment of the method, a characteristic field which, when the system is started, sets parameter values for starting values for the variables to be set, is changed. Thus, these starting values can be constantly improved by a self-learning system.
Weitere vorteilhafte Ausgestaltungen des Verfahrens ergeben sich aus der Zeichnung und ihrer Beschreibung. Dabei zeigen:Further advantageous embodiments of the method will become apparent from the drawing and its description. Showing:
