Abstract
An electrical control system for an electrically heated window in a motor vehicle has a voltage source including a generator, a voltage regulator for regulating a generator output voltage, a transformer switched between the generator and a heating window, the generator output voltage being increased before supplying to the heatable window, and a unit for measuring a temperature of the transformer and interrupting a communication between the transformer and the voltage source in the event of exceeding an adjustable limiting temperature.

An electrical control system for an electrically heated window in a motor vehicle, comprising a voltage source including a generator;
- a voltage regulator for regulating a generator output voltage;
- a transformer switched between said generator and a heating window, the generator output voltage being increased before supplying to the heatable window;
- and means for measuring a temperature of said transformer and interrupting a communication between said transformer and said voltage source in the event of exceeding an adjustable limiting temperature, said transformer and said window being dimensioned so that a temperature measured at said transformer can be connected with a temperature of the heating window.
