Publication number: 20140060185Abstract: A device for measuring yaw rate, having a mechanical yaw rate sensor, which has an inert mass that can be set into a primary vibration along a primary axis by means of an excitation device and can be deflected along a secondary axis extending transversely with respect to the primary axis so that when a yaw rate occurs about a sensitive axis extending transversely with respect to the primary and to the secondary axis, said device carries out a secondary vibration excited by the Coriolis force. A sensor element detects an amplitude-modulated signal for the secondary vibration. A sigma-delta modulator has a low pass filter connected to the sensor element, a quantizer and a secondary actuator disposed in a feedback path for applying a force which counteracts the Coriolis force.Type: ApplicationFiled: December 1, 2011Publication date: March 6, 2014Applicants: HAHN-SCHICKARD-GESELLSCHAFT FUR ANGEWANDTE FORSCHUNG E.V., ALBERT-LUDWIGS-UNIVERSITÄT FREIBURGInventors: Stefan Rombach, Thomas Northemann, Michael Maurer, Mattias Dienger, Yiannos Manoli
