1. whether the self-diagnosis device of acceleration or angular-rate sensor is normally diagnosed the sensor main body of sense acceleration or angular velocity, wherein, possesses:

  • Diagnosis control portion by described sensor main body being applied the inspection signal of prescribed level, gives pseudo-acceleration or angular velocity to described sensor main body;

    Integral operation portion carries out integration to responding described inspection signal from the sensor signal of described sensor main body output;

    AndWhether detection unit has passed through the integrated value that obtains during predefined integral time accordingly with the individual difference of sensor main body during from the integration of beginning sensor signal and has judged in the normal range of regulation to described integral operation portion.
