ABSTRACT:
The present invention provides a method and an apparatus for selecting a valid signal from a plurality of redundant sensor signals wherein the sensor signals may include a plurality of measured and modelled signals. The invention comprises a circuit for generating a plurality of first pass/fail signals by performing a series of tests on the sensor signals. The invention further comprises circuitry for assigning a plurality of weighted values to each of the measured sensor signals according to the first and second pass/fail signals wherein the second pass/fail signals are initialized as pass signals. The invention further comprises of circuitry for summing the weighted values for each measured sensor signal and generating second pass/fail signals for each measured sensor signal. The invention also includes circuitry for assigning selection flags to each sensor signal according to the first and second pass/fail signals and circuitry for selecting the valid signal from the selection flags.
