Abstract

A device for determining a rotation rate is described, in which by means of digital evaluation circuits the output signals of a rotation rate sensor are evaluated. By identification of the transfer function from the electronically generated oscillation voltage that excites the oscillating body carrying the acceleration elements, to the output of the acceleration elements, or by identification of the transfer function from the electrically generated test voltage at the input of the acceleration elements to their output, the systematic errors of the rotation rate sensor are determined and taken into account in the digital sensor signal processing, with the aid of which the rotation rate is unequivocally determined.
