Abstract
An offset diagnosing and correcting section obtains an offset correction value from an angular rate value obtained from detection signals produced from a plurality of angular rate sensors and a detection signal produced from an angular rate sensor when an automotive vehicle is in a stopped condition. The offset diagnosing and correcting section performs an offset correction for the angular rate value with reference to this offset correction value. A sensor sensitivity diagnosing section detects a turning condition of the automotive vehicle based on detection signals of the plurality of angular rate sensors, and diagnoses the sensitivity of the plurality of angular rate sensors based on offset corrected angular rate values of these angular rate sensors when the automotive vehicle is in a turning condition.
