Method for noise-reduced operation of rotation rate sensors in the presence of high-frequency vibrations, and correspondingly noise-reduced rotation rate sensor

A method for operating a rotation rate sensor, the rotation rate element including:

• a drive mass element arranged above a surface of a substrate which can be driven by a drive device to oscillate along a first axis running along the surface,
• a detection mass element which can be deflected along a second axis by an action of a Coriolis force, and
• a detection device by which the deflection of the detection mass element along the second axis can be detected, wherein the second axis runs perpendicularly to the first axis, and
• a device configured to frequency-shift an interference mode of the rotation rate sensor to reduce noise or to reduce offset jumps;
• wherein the rotation rate sensor is micromechanically constructed,
• the method comprising the following steps:
• exciting the detection mass element to oscillate along a first direction;
• detecting a Coriolis deflection of the detection mass element along a second direction, which is perpendicular to the first direction, using the detecting device;
• measuring noise in the rotation rate sensor;
• based on increased noise, changing operating parameters to cause a frequency shift of an interference mode.
