Abstract
The present invention presents an angular velocity sensor having a self diagnosis function. An angular velocity sensor of the present invention includes a driving part for stably vibrating a driving part of a sensor element having a driver part and a detector part for detecting an angular velocity. The angular velocity sensor also includes a detection means for detecting the angular velocity of the sensor element. The angular velocity sensor obtains a self diagnosis signal for a malfunction by detecting a mechanical coupling signal obtained at the detection means.
