ABSTRACT:
A yaw rate sensor failure diagnosing device judges whether the yaw rate sensor is failure or not. In particular, when the vehicle is in the steady turn state, the failure is judged by comparing a yaw rate value from the yaw rate sensor with a yaw rate value calculated on the basis of the value of the tire force acting on each wheel. Furthermore, the vehicle is in the non-steady turn state, the failure is judged by comparing a yaw moment value calculated from the yaw rate value from the yaw rate sensor with a yaw moment value calculated on the basis of the value of the tire force acting on each wheel.
