摘要： A device for measuring an angle and/or the torque acting on a rotatable body is proposed according to the invention, whereby the rotational angle is detected by means of magnetic or optical sensors. In particular, in a preferred exemplary embodiment, two devices (7, 8) are proposed, each of which comprises two optically readable code tracks. The two code tracks (1a, 1b or 2a, 2b) on one device (7 or 8) are similar in design and are offset in relation to each other, so that associated sensors (4) output a digital signal. The rotational angle is calculated based on the lag between the two digital signals. In a further embodiment it is provided that a torsion element (5) having a known torsional stiffness is situated between the two devices (7, 8). Torque transferred by the rotatable body (3) can also be calculated therefore from the angular difference of the two devices 7, 8. The device is used preferably in the steering axle of a motor vehicle.

摘要： The measuring device for contactless determination of a rotation angle includes a rotatable permanent magnet (22) arranged in a stator (10) made of magnetically conductive material and including two stator segments (13,14) and a surrounding cup-shaped housing part (11). One stator segment (14) is mounted directly on the bottom (15) of the housing part (11) so that a magnetically conductive connection exists. A layer (18) of magnetically nonconductive material is present between the other stator segment (13) and the bottom (15) so that no magnetic flux is possible there. The rotatable permanent magnet (22) is arranged so that it is movable in an air gap between the two stator segments (13,14) and the housing part (11) with the direction of magnetic polarization oriented radially, i.e. toward the stator segments (13,14) or in the opposite direction. The measuring element (20) is arranged in the slot (12) between the two stator segments (13,14). Because of this structural design, it is possible to divide the magnetic flux so that a shift in the linear measurement range is possible so that no sign change occurs within the linear measurement range.

摘要： A method and an arrangement (15) for detecting the actuation of an operator-controlled element (1) make possible a reliable detection of an operator-controlled function to be activated by the operator-controlled element (1) independently of environmental and wear conditions. The operator-controlled element (1) can be actuated with different adjustable degrees of actuation. Various operator-controlled functions of the operator-controlled element (1) are realized in dependence upon the degree of actuation. The operator-controlled element (1) is actuated against a spring force and at least two degrees of actuation are characterized by different spring constants. The at least one of the operator-controlled functions of the operator-controlled element (1) is detected in dependence upon the spring constant assigned to the instantaneous degree of actuation.

摘要： A partially redundant, contactless pedal-travel sensor is used for controlling a vehicle. This pedal travel sensor generates at least two redundant signals using a contactless sensor and an electronic circuit. These signals are fed to a control and/or regulating unit, where they are subjected to a plausibility check to detect a faulty pedal-travel sensor. To improve safety during a failure of a pedal-travel sensor and to improve the diagnostic options, it is provided that a specific position of the pedal is detected by a switch and a signal is generated by the switch. Then a plausibility comparison of the signal generated by the switch with the signals generated by the pedal-travel sensor is performed.

摘要： A measuring device for contactless detection of an angle of rotation is comprised of a supporting plate (14) made of soft magnetic material which is used as a rotor. In a plane in relation to the supporting plate (14), two segments (16, 17) are disposed, which are separated by means of a slot (21) and a spacer gap (22). The supporting plate (14) is fastened to an axle (11) whose extension (12) or the axle (11) itself is comprised of a magnetically conductive material. The extension (12) protrudes into one of the segments (16) of the stator. The axle (11), particularly its extension (12), the supporting element (14), and the segments (16, 17) control the magnetic flux of the permanent magnet (15) disposed on the supporting plate (14). Through the inclusion of the axle (11) into the magnetic flux, the measuring device is constructed in a relatively simple and space-saving manner.

摘要： A measuring instrument (10) for contactless ascertainment of a rotation angle is made up of a support plate (12) that is comprised of magnetically nonconductive material and serves as a rotor. A permanent magnet (15), which is embodied as planar, is disposed on the support plate (12) and its polarization direction is aligned diametrically to the axle (11). If the Hall element (20) is asymmetrically disposed, i.e. if the Hall element (20) describes an elliptical rotary motion in relation to the permanent magnet (15), then a steeply decreasing region and a flat region are produced in the curve of the output signal. No magnetic flux conducting parts are required in the measuring instrument (10). Furthermore, it is very small and relatively easy to incorporate into systems and devices.
