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.
