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.

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 &#x201c;second axial&#x201d;/&#x201c;radial toothing&#x201d; (ST) on one SS end, the FT/ST mutually engaging form-fittingly; the connection in the RD is within the BF ID, and in the AD is within the AE of the BF; and the FS by another end facing away from the FT, and the SS by another end facing way from the ST, protrude axially from the BF.

Sensor device for measuring a linear or rotational movement of a measurement object

An air spring includes a cover, a base element and a flexible bellows clamped in a pressure-tight fashion between the cover and base element. A level-measuring device, integrated at least partially into the bellows, detects the height of the air spring. The level-measuring device has at least the following: a) at least one angle sensor which is integrated into the bellows, is connected at least in a rotationally fixed fashion to the cover or the base element and has an element which can rotate with respect to a base, b) a mechanical coupling, which is connected, at one end, to the rotatable element of the angle sensor and at the other end, to the cover or to the piston, such that when the height of the air spring changes an angle of at least one element of the mechanical coupling is changed and the angle sensor generates an angle signal which is dependent on the change in angle of the element, c) an evaluation device which assigns the angle signal originating from the angle sensor to a height level of the air spring.
