Abstract
A yaw-rate-sensor's anomaly detecting apparatus of the invention comprises a road-surface-condition determining device for determining a road surface condition and a yaw-rate-sensor's anomaly determining device for determining that a yaw rate sensor is abnormal, when a change amount of yaw rate outputted from the yaw rate sensor exceeds an anomaly determination threshold, wherein the yaw-rate-sensor's anomaly determining device sets one of different anomaly determination thresholds varying according to determination results by the road-surface-condition determining device. This can suppress erroneous determination of anomaly of the yaw rate sensor due to running on a bad road.
