Circuit arrangement and method for an electronic system for time-delayed outputting of a switching signal

A method for computational and measurement determination of a predetermined time delay and for the processing of a time delay which is relevant for the outputting of the switching signal of a circuit arrangement including a first and second timer and an actuating element, the method comprising:

• determining a total resistance representative of a respective resistance of the first and the second timer and of the actuating element;
• determining a first resistance element which represents the respective resistance of the first timer and of the actuating element;
• computationally determining a second resistance element, representative of the respective resistance of the second timer and of the actuating element, by subtracting the determined first resistance element from the determined total resistance;
• determining via measurement, the second resistance element, representative of the respective resistance of the second timer and of the actuating element;
• and
• comparing the computationally determined second resistance element with the second resistance element determined by measurement and time-delay outputting the switching signal as a function of the comparison.

A circuit arrangement for an electronic system for time-delayed outputting of a switching signal, comprising:

• first timer means for converting an input signal to a first time-delayed output signal;
• second timer means for converting the input signal to a second time-delayed output signal, wherein the second timer means is redundant with respect to the first timer means;
• common actuating means for the input signal for both the first and the second timer means;
• and
• control means, for each timer means, for computational and measurement determination of the time delay, which is predetermined by use of the actuating means, and for processing of a time delay which is relevant for the outputting of the switching signal.
