摘要： Disclosed is a method for the detection of local displacements and rotations, wherein a sum signal and additionally a difference signal are formed from two separately generated signals of two transformer elements (W1, W2) which are distanced from each other, whereupon the sum signal and the formed difference signal are OR operated. Also disclosed is a moving incremental scale local frequency doubling device. Said device comprises an encoder (1a, 1b, 1c), a magnetically sensitive converter (9, 13) and a signal conditioning stage (6a,6b) electrically connected thereto. The transformer comprises at least two sensorially active functional groups contemporaneously using sensorially active groups or sub-groups (W1, W2) which are locally offset in relation to each other by a local phase φ in order to scan the moving scale and the functional groups comprise means enabling at least two independent partial signals S1 = V * sin (ω t) and S2 = -V * sin (ω t+ φ) to be produced.

摘要： The description relates to a device for detecting rotary movements consisting essentially of a measurement transmitter (8) which rotates with the rotating part and a stationary measurement detector (14, 15, 16) which contains a magneto-resistive sensor component (1, 1') with a bias magnet (7, 11). The measurement transmitter is an encoder (8) having successive permanently magnetic areas (9) of alternating polarity in the direction of rotation (Y direction). The sensor component (1, 1') is arranged and the bias magnet (7, 11) is magnetised in such a way that, on a rotary movement through the magnetised areas (9) in a preferred direction of the sensor component (Y direction) which is perpendicular to the magnetic field component (in the X direction) generated by the bias magnet (7, 11), a varying magnetic field component passing through the magneto-resistive sensor component (1, 1') in the Y direction and reproducing the rotary movement is produced between the adjacent permanent magnet areas (9).

摘要： The invention concerns a sensor element (2) which in normal operation emits information merely as to whether two or more field-sensitive components are located in peripheral regions of identical or different electromagnetic field intensities of a pulse generator (1). In order that these sensor elements can also enable it to be ascertained as soon as a supply voltage is switched on whether an identical electromagnetic field intensity at both components corresponds to a region of lower (L) or higher (H) field intensity, the invention proposes that when the supply voltage is switched on, the sensor element is first operated such that the absolute field intensity is measured for a given time. If there is a differential connection between two field-sensitive components (3, 4), one of the components is temporarily switched off, both components are connected in parallel or both components are connected in series.

摘要： The invention relates to a device for the reliable analysis of measurement results obtained by sensing, characterized in that it makes isochronous use of several independent measuring channels (10, 11) with several independent measurement ranges which are supplied with signals by a shared yaw rate measuring element. The advantages of the invention are essentially as follows: only one expensive yaw rate measuring element is required which parallely supplies different vehicle systems with measurement data. In the cross-over zone of the measurement ranges the measurement ranges of different systems can be used simultaneously for mutual monitoring (redundancy function). Lastly, identical measurement channels can be run redundantly on an additional or exclusive basis and thus improve the operating safety of the vehicle system.

摘要： The invention relates to an assembly (30) for determining a measurement quantity for a braking force acting on a brake, comprising a carrier (1) and a brake holder (2). The aim of the invention is for the assembly to enable precise and reproducible measurements of a measurement quantity characteristic of the braking force. This aim is achieved in that the brake holder (2) is arranged in such a way that the brake holder can be elastically and laterally displaced with respect to the carrier (1), wherein the brake holder (2) is fastened to the carrier by means of at least one elastic bending element (4a, 4b), wherein a sensor device (36) is provided for determining the displacement distance (Δx) of the brake holder with respect to the carrier (1).

摘要： The invention relates to an active magnetic field sensor, especially a wheel-bearing sensor unit, comprising at least one magnetic sensor element (10, 21, 36) for converting a temporally periodic magnetic field into a temporally periodic electrical sensor signal at signal outputs (37, 31); and an electronic signal evaluation circuit. The magnetic field sensor is supplied with electricity via a sensor interface. Periodic signals (38, 39) of the magnetic field sensor element are actively electrically processed in two or more separate signal channels of the evaluation circuit, allocated to the sensor signals, respectively.

摘要： Method for determining the mapping error in a wheel speed sensing system composed of a magnetic encoder (E) which rotates with the wheel and which is magnetically coupled to a wheel speed sensor (S) across an air gap (M) which has a specific length (L), in which the wheel speed sensor (S) can sense both the wheel speed and the average magnetic field strength in the air gap and output them electronically in a defined fashion, and an electronic control unit (ECU) in which, during a specific driving state of the motor vehicle, the wheel speed sensor (S) measures the average magnetic field strength in the air gap (M), after which the actual pole pitch mapping error of the encoder (E) affecting the data of the wheel speed sensor (S) is determined from the average magnetic field strength in the magnetic air gap (M) and the evaluation of a reference characteristic curve which is stored electronically and gives the relationship between the standardized air gap length and the mapping error and the standardized field strength.
