Abstract

A yaw rate sensor having a substrate and a seismic mass is described, in which the seismic mass is excitable to a working oscillation relative to the substrate via a drive unit, and a Coriolis deflection of the seismic mass is detectable relative to the substrate, in which the yaw rate sensor furthermore has an interrupt interface, the drive unit being configured to reduce a frequency and/or an amplitude of the working oscillation if an interrupt signal is present at the interrupt interface.
