1. An apparatus for detecting angular velocity and acceleration, comprising:

  • a vibrator unit which vibrates in first and second directions perpendicular to each other;

    means for detecting a displacement amount of the vibrator unit as the angular velocity when the vibrator unit is displaced in the second direction due to generation of an angular velocity while the vibrator unit is vibrated in the first direction;

    means, when vibrator units are displaced in first and second directions due to generation of an acceleration, for detecting displacement amounts in the first and second directions of the vibrator units as accelerations in the first and second directions; and

    means for diagnosing functions of the means for detecting the angular velocity and the means for detecting the accelerations, whereinsaid apparatus outputs a sensor signal including the detected angular velocity and the detected acceleration, and a result of diagnosis together to an external device in response to a single communication demand from the external device.
