    摘要: A micromechanical rotation rate sensor has a seismic mass and driving devices which cause a driving vibration of the seismic mass in a first direction x. The rotation rate sensor has measuring devices which measure a deflection of the seismic mass in a second direction y, and generate a deflection signal. The deflection includes a measurement deflection caused by a Coriolis force and an interference deflection, the interference deflection being phase-shifted with respect to the measurement deflection by 90°. Compensation devices are provided at the seismic mass to reduce the interference deflection. Regulation devices are provided, to which the deflection signal is supplied as an input variable, which demodulate an interference deflection signal from the deflection signal, and which generate a compensation signal from the interference deflection signal, which is supplied to the compensation devices.

    摘要: A yaw rate sensor includes a drive mass element which is situated above a surface of a substrate and is drivable to vibrate by a drive device along a first axis extending along the surface, having a detection mass element, which is deflectable under the influence of a Coriolis force along a second axis perpendicular to the surface, and having a detection device by which the deflection of the detection mass element along the second axis is detectable. Due to the arrangement of the second axis perpendicular to the surface, the yaw rate sensor may be integrated into a chip together with additional yaw rate sensors suitable for detection of rotations about axes of rotation in other directions.
