Abstract:
1. A method for producing a test signal for a measurement of the measurement sensitivity of a rotation rate sensor, the rotation rate sensor including a seismic mass and a substrate configured to detect a Coriolis force, comprising: producing an antiphase oscillation of at least two seismic masses on an oscillation plane; influencing a Coriolis force on the seismic masses; deflecting the seismic masses at right angles to the oscillation plane, based on the Coriolis force; influencing a stress on the rotation rate sensor; producing a structural deviation of the rotation rate sensor by the influencing stress, wherein the structural deviation includes a deformation of the seismic mass or deformation of the substrate; varying the measurement sensitivity of the rotation rate sensor based on the structural deviation; and producing a test signal, which is independent of the structural deviation of the rotation rate sensor produced by the Coriolis force, for measurement of the measurement sensitivity of the rotation rate sensor based on the measured structural deviation.
