Abstract

A yaw-rate sensor is described as having a substrate which has a main plane of extension for detecting a yaw rate about a first axis extending parallel to the main plane of extension is provided, the yaw-rate sensor having a first rotation element and a second rotation element, the first rotation element being drivable about a first axis of rotation, the second rotation element being drivable about a second axis of rotation, the first axis of rotation being situated perpendicularly to the main plane of extension, the second axis of rotation being situated perpendicularly to the main plane of extension, the first rotation element and the second rotation element being drivable in opposite directions.

Dependent claims

A yaw-rate sensor, comprising:

a substrate, which has a main plane of extension for detecting a yaw rate about a first axis extending parallel to the main plane of extension;
a first rotation element;
a second rotation element, wherein the first rotation element is drivable about a first axis of rotation, wherein the second rotation element is drivable about a second axis of rotation, wherein the first axis of rotation is situated perpendicular to the main plane of extension, wherein the second axis of rotation is situated perpendicular to the main plane of extension, and wherein the first rotation element and the second rotation element is drivable in opposite directions;
wherein the first rotation element is configured as an outer ring, wherein the second rotation element is configured as an inner ring, wherein the first rotation element is situated inside the second rotation element, and wherein the first axis of rotation runs through the second axis of rotation.

A method for operating a yaw-rate sensor, the method comprising:

driving a first rotation element about a first axis of rotation of the yaw-rate sensor, which has a substrate which has a main plane of extension for detecting a yaw rate about a first axis extending parallel to the main plane of extension, wherein the first rotation element and a second rotation element are situated;
and
driving the second rotation element about a second axis of rotation, the first axis of rotation being situated perpendicularly to the main plane of extension, the second axis of rotation being situated perpendicularly to the main plane of extension, the first rotation element and the second rotation element being driven in opposite directions;
wherein the first rotation element is configured as an outer ring, wherein the second rotation element is configured as an inner ring, wherein the first rotation element is situated inside the second rotation element, and wherein the first axis of rotation runs through the second axis of rotation.
