Description

Die Erfindung bezieht sich auf eine Sitzheizung für Fahrzeuge, insbesondere Kraftfahrzeuge, mit einem unterhalb der Sitzfläche angeordneten, über ein Steuergerät elektrisch bestromten Heizdraht, dessen elektrischer Widerstand mit Hilfe einer im Steuergerät hinterlegten Widerstands-/Temperaturkennlinie zur Ermittlung der Sitzflächentemperatur auswertbar ist.The The invention relates to a seat heater for vehicles, especially motor vehicles, with one below the seat arranged over a control unit electrically energized heating wire whose electrical resistance with the help of a in the control unit deposited resistance / temperature characteristic curve to determine the Seat surface temperature evaluable is.

Eine durch die DE 38 18 974 C2 bekannte regelbare Sitzheizung weist einen Heizwiderstandsdraht und zusätzlich, zur Erfassung der Sitzflächentemperatur, einen temperaturabhängigen Widerstand auf, mit dem punktuell die Sitztemperatur erfasst werden kann. Das bedeutet, dass pro Sitz bzw. pro Sitzheizungsfläche (mindestens) ein temperaturabhängiger Widerstand, inklusive Zubehör, wie Stecker, Leitungen, Kontakte und Auswerteelektronik im ansteuernden Steuergerät, z. B. Klimabedienteil, erforderlich ist. Zudem kann die Temperatur nur an einer Stelle erfasst werden. Es könnten auch lokale Überhitzungen auftreten, wenn z. B. wärmeisolierende Materialien auf den Sitz gelegt sind und diese die Stelle, an welcher sich der Fühler befindet, nicht bedecken.One by the DE 38 18 974 C2 known adjustable seat heating has a Heizwiderstandsdraht and in addition, for detecting the seat temperature, a temperature-dependent resistance, with the punctually the seat temperature can be detected. This means that per seat or per seat heating surface (at least) a temperature-dependent resistance, including accessories, such as plugs, lines, contacts and transmitter in the controlling controller, z. B. Climate control unit, is required. In addition, the temperature can only be detected at one point. It could also local overheating occur when z. B. heat insulating materials are placed on the seat and they do not cover the place where the sensor is located.

Nachteile bei den bekannten Sitzheizungen mit Temperaturregelung bestehen darin, dass sie eine sehr exakte Ermittlung der Kennlinie, elektrischer Widerstand, aufgetragen über der Sitzflächentemperatur, voraussetzen, was ein entsprechend genaues Vermessen der Sitzheizungsleistungswiderstände erfordert. Die ermittelte Kennlinie muss dann dem ansteuernden Gerät, z. B. Sitzheizungssteuergerät, Klimabedienteil, mitgeteilt werden. Dieser Vorgang ist zeitaufwendig und – da er vom Kundendienst, Werkstatt etc. vorgenommen werden muss – schwierig zu realisieren.disadvantage exist in the known seat heaters with temperature control in that they make a very accurate determination of the characteristic, electrical Resistance, applied over the seat surface temperature, assume what a correspondingly accurate measurement of the seat heater power resistors requires. The determined characteristic must then be the driving device, z. B. Seat heating control unit, Climate control unit, to be communicated. This process is time consuming and since he must be made by customer service, workshop, etc. - difficult to realize.

Aufgabe der vorliegenden Erfindung ist es, eine Sitzheizung zu schaffen, deren Temperatur sich unter Vermeidung des bei bekannten Sitzheizungen erforderlichen Aufwands, exakt regeln lässt.task the present invention is to provide a seat heating, their temperature while avoiding the required in known seat heaters Expenditure, can be regulated exactly.

Gemäß der Erfindung wird die Aufgabe bei einer Sitzheizung der eingangs bezeichneten Gattung durch gelöst, dass zur Bestimmung einer Sitzheizungssteuerungs-Kennlinie die durch das Steuergerät zu ermittelnde Innentemperatur des Fahrgastraumes dient.According to the invention The object is in a seat heating of the initially described Genus solved by that for determining a seat heating control characteristic by the the control unit to be determined inside temperature of the passenger compartment is used.

Zur Ermittlung der Innentemperatur kann im Fahrgastraum ein Temperaturfühler angeordnet sein, z. B. in einem Klimabedienteil. Über den Fahrzeugbus kann diese Temperatur an verschiedene Steuergeräte verteilt werden. Das Verteilen kann z. B. in dem Moment geschehen, wenn die Tür geöffnet wird. Ein Messen der Innentemperatur und der Sitzheizungstemperatur (z. B. über die Strom-Spannungsmessmethode) im Augenblick der Türöffnung stellt sicher, dass auf dem Sitz noch keine Person sitzt und den Sitz erwärmt.to Determining the internal temperature can be arranged in the passenger compartment a temperature sensor be, z. B. in a climate control panel. About the vehicle bus can this Temperature to be distributed to various control devices. Distributing can z. B. happen in the moment when the door is opened. A measurement of the Internal temperature and seat heating temperature (eg via the Current-voltage measurement method) at the moment of the door opening ensures that No one sits on the seat and warms the seat.

In weiterer Ausgestaltung der Erfindung wird für eine Sitzheizung, bei der der elektrische Heizdraht in Abhängigkeit von der aktuellen Sitzflächentemperatur bestromt wird, vorgeschlagen, zur Ermittlung der aktuellen Sitzflächentemperatur nicht nur die jeweilige Innentemperatur des Fahrgastraumes, sondern auch die Standzeit des Fahrzeugs zu verwenden. Hierfür sollte eine Standzeitdauer zugrundegelegt werden, nach der die Sitzflächentemperatur der Innentemperatur des Fahrgastraumes entspricht. Denn die Sitzoberflächentemperatur gleicht sich unter bestimmten Bedingungen der Innentemperatur im Fahrzeug an, z. B. wenn das Fahrzeug eine bestimmte Zeitdauer (etwa 3 Stunden) gestanden hat und hierbei keiner Sonnenbestrahlung ausgesetzt war (z. B. Überprüfung durch einen Sonnensensor).In Another embodiment of the invention is for a seat heating, in the the electric heating wire in dependence from the current seat temperature is energized, proposed to determine the current seat temperature not only the respective interior temperature of the passenger compartment, but also to use the service life of the vehicle. For this should a service life is taken as the seating temperature the internal temperature of the passenger compartment corresponds. Because the seat surface temperature resembles the internal temperature in the vehicle under certain conditions on, for. For example, if the vehicle has a certain amount of time (about 3 hours) has stood and in this case was exposed to sunlight (eg check by a sun sensor).

Für den Fall, dass das Fahrzeug eine Außentemperaturmessung besitzt, kann zur Ermittlung der erforderlichen Standzeitdauer ein Vergleich der Innentemperatur mit der Außentemperatur dienen. Denn wenn die Innentemperatur annähernd gleich der Außentemperatur ist, was eine gewisse Zeitdauer voraussetzt, in der der erforderliche thermische Ausgleich stattfinden kann, entspricht die Sitzflächentemperatur folgerichtig der Innen- wie der Außentemperatur.In the case, that the vehicle is an outside temperature measurement possesses, may be used to determine the required service life Comparison of the internal temperature with the outside temperature serve. Because when the inside temperature is approximate equal to the outside temperature is what presupposes a certain amount of time in which the required thermal compensation can take place, corresponds to the seat surface temperature consistent with the indoor and outdoor temperature.

In vorteilhafter Weiterbildung der Erfindung kann zur Ermittlung einer Sitzheizungswiderstands-/Sitzheizungstemperatur-Kennlinie der elektrische Widerstand des Heizdrahts und die ermittelte jeweilige Sitzflächentemperatur verwendet werden. Damit macht sich die Erfindung die bekannten Messverfahren nach dem Stand der Technik zur Ermittlung des Sitzheizungswiderstands zunutze und bringt als zweiten Wert zur Findung der Sitzheizungswiderstands-/Sitzheizungstemperatur-Kennlinie die erfindungsgemäße Sitztemperaturerfassung ein.In Advantageous development of the invention can be used to determine a Seat heating resistance / seat heating temperature characteristic of the electric Resistance of the heating wire and the determined respective seat temperature be used. Thus, the invention makes the known measuring methods according to the prior art for determining the seat heater resistance takes advantage and brings as a second value for finding the Sitzheizungswiderstands- / Sitzheizungstemperatur characteristic the seat temperature detection according to the invention one.

Dieses Vorgehen kann vorteilhafterweise auch allmählich zur Erhöhung der Kennliniengenauigkeit, z. B. über verschiedene erfasste Temperaturen, führen.This Procedure can also be used gradually to increase the Characteristic accuracy, z. B. over different recorded temperatures, lead.

Insgesamt gesehen ermöglicht die Erfindung Kosteneinsparungen, indem sie den bei bekannten Sitzheizungen der in Rede stehenden Art getriebenen Aufwand verringert.All in all seen possible The invention provides cost savings by having the known seat heaters reduced the effort in question type.

Zur praktischen Realisierung der Erfindung wird in weiterer Ausgestaltung derselben vorgeschlagen, dass ein nach kurzzeitiger Bestromung des Heizdrahts ermittelter Sitzheizungswiderstand und die ermittelte Fahrgastraum-Innentemperatur als erster Näherungswert einer Sitzheizungs-Kennlinie dienen. Hierbei ist eine im Steuergerät als „Grundkennlinie" abgelegte Widerstands-/Temperaturkennlinie jeweils durch die aktuell ermittelte Sitzheizungs-Kennlinie angleichbar. Damit kann die im Steuergerät als „Grundkennlinie" abgelegte Widerstands-/Temperaturkennlinie durch jede erfolgreiche Bedienung der Sitzheizung um 10% oder einen ähnlichen Wert an die aktuell ermittelte Sitzheizungs-Kennlinie angeglichen werden.For the practical realization of the invention, the same is proposed in a further embodiment thereof gene that a short-term energization of the heating wire determined seat heating resistor and the determined passenger compartment interior temperature serve as a first approximation of a seat heating characteristic. In this case, a resistance / temperature characteristic stored in the control unit as a "basic characteristic" can be adjusted by the currently determined seat heating characteristic, so that the resistance / temperature characteristic stored in the control unit as "basic characteristic" can be reduced by 10% or a similar one by each successful operation of the seat heating Value to be matched to the currently determined seat heating characteristic curve.

Zusätzlich denkbar ist darüber hinaus eine sukzessive Angleichung an die Benutzereigenheiten: Nimmt man einmal an, dass ein Benutzer immer Sitzheizungsstufe 6 fährt, so könnte man die Sitzheizung umkalibrieren und sukzessive auf untere Stufen gehen, d. h. der Benutzer kann dann nach einiger Zeit auf Stufe 5 oder 4 wechseln und verspürt ähnliche Wärme wie früher in Stufe 6. Es wäre auch möglich, dieses benutzerspezifische Verhalten, z. B. mittels Fingerprintsensor oder schlüsselspezifisch im Steuergerät abzulegen.Additionally conceivable is about it in addition, a successive approximation to the user's properties: Takes suppose that a user always drives seat heating level 6, so could recalibrate the seat heating and gradually to lower levels go, d. H. the user can then go to stage after some time 5 or 4 switch and feel similar heat as earlier in stage 6. It would be also possible, this user-specific behavior, eg. B. by means of fingerprint sensor or each key individually in the control unit store.
