Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Regelung eines Kühlsystems für eine Brennkraftmaschine in einem Fahrzeug gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a device for controlling a cooling system for one Internal combustion engine in a vehicle according to the preamble of the claim 1.
Beim Betrieb von modernen Brennkraftmaschinen werden Kennfeldthermostate zur Regelung der Kühlwassertemperatur in einem Kühlsystem einer Brennkraftmaschine eingesetzt, um beispielsweise in Abhängigkeit von einem Last- und Drehzahlsignal unterschiedliche Kühlwassertemperaturen einzustellen. Dabei erfolgt die Regelung der Thermostatventile durch die Steuereinheit der Brennkraftmaschine. In einer solchen Steuereinheit werden unterschiedliche Wassertemperaturen betriebspunktabhängig in einem Kennfeld abgelegt. Demnach wird die Kühlwassertemperatur nach bestimmten Vorgabewerten durch eine elektrische Ansteuerung des Kennfeldthermostaten geregelt. Wird die Brennkraftmaschine in einem Teillastbereich betrieben, können beispielsweise in einem stationären Betrieb Kühlwassertemperaturen zwischen 105°C und 110°C eingestellt werden, wobei in einem Volllastbetrieb der Brennkraftmaschine niedrigere Kühlwassertemperaturen, ca. um 90°C, eingestellt werden. Hierdurch wird im Teillastbereich durch die höher eingestellten Kühlwassertemperaturen der Kraftstoffverbrauch der Brennkraftmaschine reduziert, wobei beim Volllastbetrieb der Brennkraftmaschine die Erzielung einer höheren Leistung ermöglicht wird.At the Operation of modern internal combustion engines become map thermostats for controlling the cooling water temperature in a cooling system an internal combustion engine used, for example, depending on different cooling water temperatures from a load and speed signal adjust. The regulation of the thermostatic valves takes place the control unit of the internal combustion engine. In such a control unit different water temperatures are operating point dependent in filed a map. Accordingly, the cooling water temperature after certain Default values by an electrical control of the map thermostat regulated. If the internal combustion engine is operated in a partial load range, for example in a stationary Operation of cooling water temperatures between 105 ° C and 110 ° C be adjusted, wherein in a full load operation of the internal combustion engine lower cooling water temperatures, about 90 ° C, be set. As a result, in the partial load range by the higher set cooling water temperatures the fuel consumption of the internal combustion engine is reduced, at full load operation of the internal combustion engine to achieve a higher performance allows becomes.
Dennoch wird bei den bisher bekannten Verfahren bei einem plötzlichen Lastsprung der Brennkraftmaschine ein Leistungsverlust festgestellt, da z.B. die Kühlwassertemperatur nicht schnell genug auf die gewünschten niedrigeren Kühlwassertemperaturen eingeregelt wird.Yet is in the previously known methods in a sudden Load jump of the engine detected a power loss since e.g. the cooling water temperature not fast enough to the desired ones lower cooling water temperatures is adjusted.
Aufgabe der Erfindung ist es daher, eine Vorrichtung zur Regelung der Kühlmitteltemperatur in einer Brennkraftmaschine derart zu gestalten, dass ein verbessertes Betriebsverhalten der Brennkraftmaschine erzielt wird.task The invention is therefore an apparatus for controlling the coolant temperature to make in an internal combustion engine such that an improved Operating behavior of the internal combustion engine is achieved.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a Device solved with the features of claim 1.
Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, dass die Schalteinrichtung, mit der eine Kühlmitteltemperatur eingestellt wird, mittels eines manuell betätigbaren Schalters in mehreren Betriebsstellungen bringbar ist, so dass die Einstellung einer bestimmten Kühlmitteltemperatur gegebenenfalls unabhängig von einem Lastpunkt der Brennkraftmaschine erzielt wird.The inventive device is characterized by the fact that the switching device, with a Coolant temperature is set by means of a manually operable switch in several Operating positions can be brought, so that the setting of a particular Coolant temperature optionally independent is achieved by a load point of the internal combustion engine.
Entsprechend einer bestimmten und wählbaren Stellung des Schalters kann z.B. die Brennkraftmaschine im gesamten Kennfeldbereich mit einer konstanten niedrigen Kühlmitteltemperatur betrieben werden, so dass auf eine Temperaturanpassung bei einem Lastsprung verzichtet werden kann und die Abrufung der vollen Leistung der Brennkraftmaschine rasch ermöglicht wird. Dagegen kann gemäß einer weiteren Stellung des Schalters ein verbrauchsgünstiger Betrieb der Brennkraftmaschine durch die Einstellung einer höheren Kühlmitteltemperatur im gesamten Kennfeldbereich der Brennkraftmaschine erzielt werden. Vorzugsweise ist die die Schalteinrichtung als eine Kennfeldthermostateinrichtung ausgebildet. Somit kann z. B. eine vom Fahrerwunsch abhängige Regelung des Kennfeldthermostaten vorgenommen werden.Corresponding a specific and selectable Position of the switch can e.g. the internal combustion engine throughout Map area are operated at a constant low coolant temperature, so that waived a temperature adjustment in a load jump can be and the retrieval of the full power of the internal combustion engine made possible quickly becomes. In contrast, according to a further position of the switch a fuel-efficient operation of the internal combustion engine by hiring a higher one Coolant temperature be achieved throughout the map range of the engine. Preferably, the switching device is a map thermostat device educated. Thus, z. B. a driver-dependent regulation of the map thermostat.
Die der vorliegenden Erfindung zugrunde liegende Idee besteht darin, dass die Regelung bzw. die Ansteuerung des Kennfeldthermostaten nicht mehr durch die Steuereinheit der Brennkraftmaschine erfolgt, sondern durch eine unmittelbar manuell ausgeführte Schalteinrichtungsstellung erzielt wird. Das führt zu einer Vereinfachung der Ansteuerung des Thermostaten.The The idea underlying the present invention is that that the control or the control of the map thermostat no longer takes place through the control unit of the internal combustion engine, but by a directly manually running Schalteinrichtungsstellung is achieved. Leading to simplify the control of the thermostat.
In einer Ausgestaltung der Erfindung ist in einer ersten Betriebsstellung der Kennfeldthermostateinrichtung die Kühlmitteltemperatur unabhängig vom Betriebspunkt der Brennkraftmaschine in einem Temperaturbereich um 90°C einstellbar. Die erste Betriebsstellung ermöglicht eine sportliche Fahrweise, da die Brennkraftmaschine im gesamten Kennfeldbereich verhältnismäßig kalt betrieben und somit eine erhöhte Klopfempfindlichkeit vermieden wird.In An embodiment of the invention is in a first operating position the map thermostat device, the coolant temperature regardless of Operating point of the internal combustion engine in a temperature range around 90 ° C adjustable. The first operating position allows a sporty driving style, because the internal combustion engine in the entire map area relatively cold operated and thus an increased Knock sensitivity is avoided.
Gemäß einer weiteren Ausgestaltung der Erfindung ist in einer zweiten Betriebsstellung der Kennfeldthermostateinrichtung die Kühlmitteltemperatur unabhängig vom Betriebspunkt der Brennkraftmaschine in einem Temperaturbereich um 105°C einstellbar. Die zweite Betriebsstellung ermöglicht einen verbrauchsgünstigen Betrieb der Brennkraftmaschine, da die Brennkraftmaschine im gesamten Kennfeldbereich mit einer höheren Kühlmitteltemperatur betrieben wird. Hierdurch wird eine Reduzierung des Kraftstoffverbrauches auch im Volllastbereich durch die geringere Motorreibung erzielt.According to one Another embodiment of the invention is in a second operating position the map thermostat device, the coolant temperature regardless of Operating point of the internal combustion engine in a temperature range around 105 ° C adjustable. The second operating position allows a fuel-efficient Operation of the internal combustion engine, since the internal combustion engine throughout Map area with a higher Coolant temperature operated becomes. This will reduce fuel consumption also achieved in the full load range due to the lower engine friction.
In einer weiteren Ausgestaltung der Brennkraftmaschine ist in einer dritten Betriebsstellung der Kennfeldthermostateinrichtung die Kühlmitteltemperatur mittels einer adaptiven Steuerung in Abhängigkeit vom Betriebspunkt der Brennkraftmaschine einstellbar. Mit einer adaptiven Steuerung der Kühlmitteltemperatur wird anhand von Betriebsparametern, die in einer Steuereinheit der Brennkraftmaschine vorgegeben sind, eine betriebspunktabhängige Steuerung der Kühlmitteltemperatur ermöglicht.In a further embodiment of the internal combustion engine is in one third operating position of the map thermostat device, the coolant temperature by means of an adaptive control as a function of the operating point the internal combustion engine adjustable. With an adaptive control the coolant temperature is determined by operating parameters, which in a control unit of the Internal combustion engine are given, an operating point-dependent control the coolant temperature allows.
