  • Patent number: 10399596
    Abstract: A sensor device includes a plurality of sensor elements and an output circuit in one sensor part, and a correction value calculator in an ECU, which obtains output signals from the sensor part and calculates an offset correction value based on a plurality of signal values that correspond to a detection value when a calculability condition is satisfied. The ECU also includes a control calculator that performs a calculation based on the corrected signal values that have been corrected by the offset correction value. Therefore, the offset correction value is calculated in view of an aging and an accuracy variation of the components used in the sensor device. In such manner, the detection value is appropriately corrected for the calculation.

  • Patent number: 10384712
    Abstract: If abnormalities of the sensor part are detected, the power-source control section temporarily stops the electric power supply from the sensor power source to the sensor part so that the sensor power source voltage Vs which is the voltage between the sensor power source and the sensor part falls. In addition, after electric power supply to the sensor part resumes, and the sensor part is recovered from the abnormalities, then, the power source control section continues the electric power supply from the sensor power source to the sensor part. When the sensor part is not recovered from the abnormalities, the power source control section stops the electric power supply from the sensor power source to the sensor part.

  • 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.

  • Patent number: 10173720
    Abstract: A sensor device includes two sensor parts and an ECU. An output division of one of the two sensor parts stops output of an output signal when a detected internal abnormality is a first abnormality. Further, when the detected internal abnormality is a second abnormality that is different from the first abnormality, the output division controls an abnormality signal to take a value indicative of the second abnormality. An abnormality determiner determines either of a signal obtainment abnormality or the first abnormality of the sensor part when the output signal is not obtained from the one of the sensor parts, or determines the second abnormality of the one of the sensor parts when the obtained output signal includes the abnormality signal having a value indicative of the second abnormality. Such determination, thus, enables the abnormality determiner to classify an abnormality caused in the sensor parts.

  • Patent number: 10077069
    Abstract: A sensor device includes a main sensor, a sub sensor, and an Electronic Control Unit (ECU). The ECU has a torque calculator that sets, as a steering torque, a main steering torque that is calculated based on a main sensor signal when a main output signal is normal. During a transition period between an abnormality detection and an abnormality establishment regarding the main output signal, the torque calculator calculates the steering torque based on (i) a sub steering torque calculated based on a sub sensor signal and (ii) a prior-to-abnormality-detection main steering torque. In such manner, even when abnormality is detected in a part of the sensor signals, a fluctuation of the steering torque due to, or accompanying, the switching of the steering torque calculation to a normal signal only calculation is prevented.
