Abstract
A yaw rate sensor is described which includes a drive device, at least one Coriolis element, and a detection device having at least two detection elements which are coupled to one another with the aid of a coupling device, the drive device being connected to the Coriolis element for driving a vibration of the Coriolis element, and an additional coupling device which is connected to the detection device and to the Coriolis element for coupling a deflection in the plane of vibration of the Coriolis element to the detection device in a direction orthogonal to the vibration.
