Abstract:
1. A sensor device comprising: a plurality of sensor integrated circuits (ICs) each of which has a plurality of detecting units that detect a same state quantity for a same detection object and that respectively output detection signals based on detection results; wherein the state quantity of the detection object is detected on the basis of each of a plurality of the detection signals that are respectively output from the plurality of detecting units of the sensor ICs, and a control device determines which detection signal is abnormal among the plurality of detection signals from the sensor ICs, on the basis of a comparison among the plurality of detection results, and wherein when at least one detection signal has been determined to be abnormal among the plurality of detection signals respectively output from the plurality of detecting units of the sensor ICs, the control device further determines which detection signal is abnormal among the remaining plurality of detection signals other than the at least one detection signal determined to be abnormal, on the basis of a comparison among the plurality of detection results that are respectively obtained from the remaining plurality of detection signals.
