Abstract
Description
Die Erfindung betrifft ein Verfahren zur Bestimmung der Temperatur einer Windschutzscheibe gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a method for determining the temperature of a Windshield according to the preamble of claim 1.
Die ermittelte Temperatur wird z.B. zum Regeln einer Klimaanlage eines Kraftfahrzeugs genutzt. Hierbei ist es wichtig, besonders die Temperatur an der Innenseite der Windschutzscheibe zu kennen, um gezielt einen möglichen Beschlag entfernen zu können.The determined temperature is e.g. to control an air conditioner Used motor vehicle. Here it is important, especially the temperature to know the inside of the windshield to target one potential To be able to remove the fitting.

Ausgehend von dem beschriebenen Stand der Technik ist es die Aufgabe der Erfindung, ein Verfahren zu schaffen, das die Bestimmung der Temperatur an einer beliebigen Stelle des Querschnitts einer Windschutzscheibe mit einfachen Mitteln erlaubt.outgoing from the described prior art it is the object of the invention to create a method that determines the temperature anywhere on the cross section of a windshield allowed by simple means.
Die Aufgabe ist durch die Merkmale des Anspruchs 1 gelöst. Dadurch, dass aus den Messwerten ein Temperaturprofil im Querschnitt der Windschutzscheibe berechnet wird, können Temperaturen an beliebigen Stellen im Querschnitt der Windschutzscheibe bestimmt werden. Hierfür sind lediglich die Messdaten von bereits am und/oder im Fahrzeug vorhandenen Temperatursensoren in eine Auswerteeinheit zu speisen, in der ein entsprechendes Rechenmodell hinterlegt ist. Die berechneten Werte können vielseitig für verschiedene Regel- und/oder Steuerfunktionen genutzt werden. Es ist also lediglich zusätzliche Rechenkapazität vorzuhalten, während bislang erforderliche zusätzliche Temperatursensoren entfallen können. Es werden mit Hilfe der Erfindung also nennenswerte Kosten eingespart.The The object is solved by the features of claim 1. Thereby, that from the measured values a temperature profile in the cross section of Windscreen is calculated, temperatures can be at any Make in the cross section of the windscreen to be determined. For this are only the measurement data of existing on and / or in the vehicle temperature sensors to feed into an evaluation unit in which a corresponding calculation model is deposited. The calculated values can be versatile for different Control and / or control functions are used. So it's just additional computing capacity to hold on while previously required additional Temperature sensors can be omitted. Significant costs are thus saved with the aid of the invention.
Weiterhin kann die Scheibentemperatur genauer als bisher bestimmt werden, weil die bekannten berührungslosen Sensoren sehr stark durch Sonneneinstrahlung und/oder Einfärbungen und Beschichtungen der Windschutzscheibe beeinflusst werden und weil auf die Windschutzscheibe geklebte Sensoren träge sind.Farther the temperature of the window can be determined more accurately than before, because the known non-contact Sensors are very strong due to solar radiation and / or coloring and windscreen coatings are influenced and because sensors glued to the windshield are sluggish.
Die Einspeisung des Temperaturverlaufs direkt oder indirekt in eine Steuereinheit einer Klimaanlage gemäß Anspruch 2 bewirkt eine besonders vorteilhafte Klimatisierung des Fahrzeug-Innenraums und gegebenenfalls eine effektive Entfeuchtung der Innenseite der Windschutzscheibe. Hierbei kann der Temperaturverlauf zunächst in z.B. einen Regen-Licht-Sensor oder einen Beschlagsensor und dann als von diesen Sensoren ausgewertetes Signal an die Steuereinheit ausgegeben werden.The Infeed of the temperature profile directly or indirectly into one Control unit of an air conditioner according to claim 2 causes a particularly advantageous air conditioning of the vehicle interior and optionally effective dehumidification of the inside of the windshield. In this case, the temperature profile can first be measured in e.g. a rain-light sensor or a fogging sensor and then as evaluated by these sensors Signal are output to the control unit.
Bei bestimmten Messvorrichtungen eines Fahrzeugs wie z.B. Regen- und Beschlagsensoren ist es erforderlich, Einflüsse aus der Temperatur der Windschutzscheibe zu kompensieren. Diese Korrekturwerte sind einfach aus der Auswerteeinheit abgreifbar.at certain measuring devices of a vehicle, e.g. Rain and Fog sensors are required to influence the temperature of the windshield to compensate. These correction values are simply from the evaluation unit tapped.
Selbstverständlich ist es möglich, den errechneten Temperaturverlauf sowohl für die Steuerung der Klimaanlage als auch gleichzeitig für die Temperaturkompensation zu nutzen, sofern die entsprechenden Vorrichtungen in dem Fahrzeug installiert sind.Of course it is it is possible the calculated temperature profile for both the control of the air conditioning as well as at the same time to use the temperature compensation, provided the appropriate Devices are installed in the vehicle.
