Patent number: 11150261Abstract: A method for producing sensor information depends on a rotational speed, using a rotational speed sensor which is adapted to output rotational speed pulses in predetermined angular positions of a physical sensor field that rotates at the rotational speed. In order to increase resolution, a digital angle signal each is determined between the pulses. A defined number of most significant bits of said angle information is output to determine the rotational speed so that the interval between two pulses is subdivided into a defined number of subintervals. An angle value which can be unambiguously interpreted by means of the sinusoidal signal can be determined from the cosine signal by using two phase shift sinusoidal signals and an arccos function. The device optionally outputs the angle signal below a threshold value and an impulse signal above the threshold value to determine speed.Type: GrantFiled: February 15, 2017Date of Patent: October 19, 2021Assignee: Continental Teves AG & Co.

Patent number: 8695424Abstract: In order to be able to perform redundant measurements of rotation rates particularly economically, disclosed herein is a sensor device which includes a dual-axis, first rotation rate sensor element with which rotation rates of rotating motions of the sensor device about a first and a second rotation rate measurement axis can be detected, wherein the first and the second rotation rate measurement axes are oriented orthogonally in relation to one another. The sensor device is defined by the fact that the sensor device includes at least one other rotation rate sensor element with which a rotation rate of a rotating motion of the sensor device about a rotation rate measurement axis, which lies in a plane together with the first and the second rotation rate measurement axes, can be deselected.Type: GrantFiled: March 11, 2009Date of Patent: April 15, 2014Assignee: Continental Teves AG & Co. oHGInventors: Bernhard Schmid, Roland Burghardt, Jörg Heimel, Otmar Simon, Roland Hilser

Patent number: 6564637Abstract: A self-testing sensor (especially to measure an angular rate or acceleration) includes a resonant structure, an actor unit configured to excite the structure to a first periodic vibration, a piezoresistive element configured to generate an output signal that depends on the measured quantity, and an isolator configured to isolate a test signal component from the output signal, whereby the test signal component is generated by a second periodic vibration of the structure superposed on the first vibration. A device for self-testing a sensor includes an isolator configured to isolate a test signal component superposed on a useful signal component from the periodic output signal of the sensor, and it includes a comparator configured to compare the test signal component with a predefined value or a test signal fed to the sensor. For the self-test, a second periodic vibration is superposed on a first vibration of the structure, and an output signal containing information on the measured quantity is determined.Type: GrantFiled: May 15, 2001Date of Patent: May 20, 2003Assignee: EADS Deutschland GmbHInventors: Josef Schalk, Erwin Stenzel, Karin Bauer, Rainer Freitag, Roland Hilser, Ralf Voss, Matthias Aikele, Helmut Seidel, Ulrich Prechtel
