Car safety sensor functionality verification procedure compares car status values derived from two different sensors with threshold difference

摘要

A car safety sensor functionality verification procedure compares (7) car status values derived (6a, b) from two different sensors including wheel rate (4a), spring load (4b), air bag pressure cyclically in defined stable states (2) during a journey and declares (9) a sensor failure if the difference exceeds a threshold. Independent claims are included for processors and car systems using the procedure.
