  • Patent number: 12092678
    Abstract: A sensor device for a vehicle, including: at least two magnetic field sensors for detecting a sensing magnetic field from a sensing magnet; in which the magnetic field sensors are configured so that the resultant magnetic field from the sensing magnetic field and an external magnetic interference field from an interference source develops a different strength of effect in different magnetic field sensors. Also described are a related method, control apparatus/unit, sensor system, and computer readable medium.
    Type: Grant
    Filed: March 26, 2020
    Date of Patent: September 17, 2024

  • Publication number: 20220113341
    Abstract: A circuit device for a vehicle, including: a printed circuit board having an operating circuit for operating a unit, a first conductor track for connecting the operating circuit to the unit, and a second conductor track for connecting the operating circuit to the unit; a detection electrode for detecting a leakage current affecting at least one of the conductor tracks; and a detection arrangement to use a signal applied to the detection electrode to provide a detection signal representing the leakage current. Also described are a related method.

  • Patent number: 10907990
    Abstract: A sensor for measuring a linear/rotating movement (LRM) of a measurement object (MO): one sensor element (SE) to detect the LRM of the MO and emit measuring signals (MS), the sensor element having encoder element (EE) and sensitive element (SeE), the SE detecting a relative movement between the EE and SeE; an electronic evaluator to evaluate the MS of the SE; a first shaft (FS) coupled to the EE by a bearing; a second shaft (SS) coupled to the MO by a bearing; the FS/SS, by a releasable connection, are mutually coupled for rotation coaxially; the bearing has central axis (CA) and cylindrical bearing face (CBF) in the axial direction (AD) parallel with the CA has an axial extent (AE), and in the radial direction (RD) perpendicular to the CA has a bearing face (BF) internal diameter (ID); the connection has a “first axial”/“radial toothing” (FT) on one FS end, and a “second axial”/“radial toothing” (ST) on one SS end, the FT/ST mutually engaging form-fittingly; the connection in the RD is within the BF ID, and
