Micromechanical yaw rate sensor having two sensitive axes and coupled detection modes
Abstract:
In a yaw rate sensor with a substrate having a main extent plane and with a first and second partial structure disposed parallel to the main extent plane, the first partial structure includes a first driving structure and the second partial structure includes a second driving structure, the first and second partial structure being excitable by a driving device, via the first and second driving structure, into oscillation parallel to a first axis parallel to the main extent plane, the first partial structure having a first Coriolis element and the second partial structure having a second Coriolis element, the yaw rate sensor being characterized in that the first and second Coriolis elements are displaceable by a Coriolis force parallel to a second axis, which is perpendicular to the first axis, and parallel to a third axis, which is perpendicular to the first and second axis, the second axis extending parallel to the main extent plane, and the first Coriolis element being connected to the second Coriolis element via a coupling element.
