METHOD FOR OPERATING A VIBRATING GYROSCOPE AND SENSOR ARRANGEMENT

摘要

The invention relates to a method for operating a vibrating gyroscope and to a sensor arrangement comprising such a vibrating gyroscope. Said vibrating gyroscope is used as a resonator and is part of at least one control circuit that excites the vibration gyroscope by feeding an excitation signal with its natural frequency. An output signal can be tapped from the vibrating gyroscope from which the excitation signal can be derived by filtering and amplification. The invention is characterized in that, once the sensor arrangement is switched on, the frequency of the excitation signal is adjusted by exciting the vibrating gyroscope, before the excitation signal is fed, to oscillate freely, measuring the frequency of the free oscillation and feeding the excitation signal to the vibrating gyroscope with the measured frequency.
