<p><P>PROBLEM TO BE SOLVED: To accurately determine a fault when any one of a group of target sensors is faulty, without causing redundancy or a cost increase. <P>SOLUTION: A fault diagnosis device for detection means, in a system having at least three sensors 11 to 13 for detecting different correlatively variable physical quantities for one physical phenomenon and outputting signals representing the detected physical quantities, converts the outputs of the at least three sensors 11 to 13 into the same physical quantity A according to the correlations to determine a sensor anomaly from the same physical quantity A converted. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
