<p>The invention is directed to a method and an arrangement for detecting faults in the context of measurement quantities in a motor vehicle. At least one measurement quantity is represented by two redundant signal values. The time-dependent changes of the signal values are determined for fault recognition and a fault condition can be assumed when the signal changes no longer correlate with each other. The arrangement for fault recognition includes an input circuit of a control apparatus to which the measurement quantities are supplied via two lines from two measuring devices. One line is provided with a resistor to ground or to the supply voltage; whereas, the other line is configured without such a resistor or has a resistor to the supply voltage or to ground having an ohmage higher than the first resistor.</p> |
