  • Patent number: 10343714
    Abstract: A sensor device includes sensors and an Electronic Control Unit (ECU). The sensors include sensor elements, a signal comparator, and a signal transmitter. The signal comparator compares a first main detection value from one of the sensor elements, and a first sub detection value from the other of the sensor elements. When the first main detection value matches the first sub detection value, the signal transmitter generates and transmits an output signal that includes a first main signal corresponding to the first main detection value without including a first sub signal corresponding to the first sub detection value. In such manner, the responsiveness of the sensor device may be improved, without deteriorating a reliability of the output signals from the sensor sections.
