Patent number: 11371824Abstract: The described techniques address the issues associated with conventional OoS sensor systems by mounting a magnetized ring onto a rotatable shaft for which an angular position is to be measured. Specific sensor configurations are disclosed regarding each magnetic sensor's position with respect to one another and each magnetic sensor's position with respect to the rotatable shaft. The described configurations provide a stray-field robust solution due to the specific magnetic sensor configurations such that, when stray fields are present, pairs of magnetic sensors are exposed to essentially the same stray field components, which thus cancel one another. Thus, the angle of the rotatable shaft as a function of the measured strength of the magnetic field components at any time instant can be calculated even in the present of stray magnetic fields.Type: GrantFiled: November 21, 2019Date of Patent: June 28, 2022Assignee: Infineon Technologies AGInventors: Gernot Binder, Benjamin Kollmitzer, Peter Slama

Patent number: 11359936Abstract: A system is provided with a magnetic field sensor being positioned in a magnetic field of a magnet that is coupled to a rotatable driving shaft. The magnetic field sensor is configured to sense a rotation of the magnetic field in response to a rotation of the rotatable driving shaft, and generate an angle sensor signal based on an orientation angle of the magnetic field.
