Abstract
A sensor device includes: multiple sensor units, each of which includes multiple sensor elements and a signal processing unit that generates and transmits an output signal including multiple detection signals corresponding to detection values of the sensor elements; and multiple control units, each of which includes a communication unit that receives the output signal, an abnormality monitoring unit that monitors abnormality of the respective sensor unit, and a physical quantity computation unit that computes a physical quantity based on at least one of the detection signals which is normal. One control unit mutually transmits and receives the detection signals as subject sensor signals received from the respective sensor unit and the detection signals as other sensor signals received from another one of the control units with another system control unit.
