Abstract

The invention relates to a method for determining the temperature (T, T 内部 ,T 外部 ), the switchable glazing has a variable transparency layer (13), the variable transparency layer being arranged for switching the glazing between two transparent conductive contact layers (14, 14'), the switchable glazing ( The control device (12) of 11) applies a voltage (V) to at least one contact layer and determines the current (I) produced by the voltage (V) in each case 内部 , I 外部 ). In this case, depending on the applied voltage (V) and the resulting current (I 内部 , I 外部 ), determine the combination of the corresponding ohmic resistance value (Rs) and / or the capacitance value (Cp) of the transparency variable layer (13) and the ohmic resistance value, and determine therefrom at least one temperature value (T 内部 ,T 外部 ).

Description

technical field [0001] The invention relates to a method for determining the temperature of a switchable pane with variable transparency. Such a "switchable pane" is a windowpane or glass panel having a layer of variable transparency which can be switched by means of two conductive contact layers in order to set its transmission rate (transparency) or light transmittance. The invention also includes a control device for carrying out the method, and a motor vehicle having at least one switchable window pane with variable transparency. Background technique [0002] An example of a transparency variable layer is an electrochromic layer. Switchable window glass or switchable glazing (switchable glazing) can be designed as SPD (Suspended Particle Device, suspended particle device) or PDLC (Polymer Dispersed Liquid Crystal Device, polymer dispersed liquid crystal device) as transparency variable layer on this basis, for example ). Another name for this type of window glass is ...
