Patent number: 10399596Abstract: 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.Type: GrantFiled: July 28, 2016Date of Patent: September 3, 2019Assignee: DENSO CORPORATIONInventors: Kouichi Nakamura, Katsuhiko Hayashi, Takaharu Kozawa, Shuji Kuramitsu, Masaya Taki, Toshimitsu Sakai

Patent number: 10343714Abstract: 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.Type: GrantFiled: July 26, 2016Date of Patent: July 9, 2019Assignee: DENSO CORPORATIONInventors: Koutarou Nakashima, Shuji Kuramitsu, Kouichi Nakamura, Masaya Taki, Toshimitsu Sakai, Takaharu Kozawa, Katsuhiko Hayashi

Patent number: 10173720Abstract: 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.Type: GrantFiled: July 28, 2016Date of Patent: January 8, 2019Assignee: DENSO CORPORATIONInventors: Takaharu Kozawa, Shuji Kuramitsu, Kouichi Nakamura, Masaya Taki, Toshimitsu Sakai, Katsuhiko Hayashi
