Beschreibung
Zusammenfassung:	A sensor control device includes a plurality of drive units for oscillating respective transducers included in a plurality of ultrasonic sensors, a driving signal generation section for generating driving signals capable of oscillating the respective plurality of transducers, a control unit having a control signal output section for outputting, to each one of the plurality of drive units, a control signal as an input command for the driving signal to the respective transducer and a bus line configured to connect the control unit to the plurality of drive units in form of a daisy-chain, the bus line being used for bidirectional communication of communication data between the control unit and the plurality of drive units based on preset time-division, the communication data being comprised of a data structure having a first band that allows superimposition of audio data thereon. Control data based on the control signal is included in the first band.
