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 is arranged in such a way that the brake holder can be elastically and laterally displaced with respect to the carrier, wherein the brake holder is fastened to the carrier by at least one elastic bending element, wherein a sensor device is provided for determining the displacement distance of the brake holder with respect to the carrier.

Electronic motor vehicle control system of modular design

Disclosed is an arrangement for detecting rotational speed of a wheel or any other rotating body by a sensor (), which is coupled via a magnetic field to an encoder () that rotates with the rotating body. If a slot between sensor element (S, S) and encoder () becomes too small in the prior art arrangements, flipping and, hence, doubling of the measured rotational speed of the wheel can occur. This caused problems in safety devices of a vehicle, which require a correct indication of the wheel rotational speed for proper operation. To improve the tolerance with respect to the mounting position of the known arrangements, two separated signal paths (S, f; S, f) are provided with sensor elements (S, S) of differing sensitivity. The signal paths (S, f; S, f) are designed so that a signal path (S, f) is always available, which is provided with a maximum rate of sensitivity so that, in the undisturbed normal case, minimum image defects of the encoder track () are achieved, simultaneously with maximum air slots, while at the same time there is always an observing signal path (S, f), whose sensitivity is rated in such a way that flipping is safely prevented in all magnetic conditions.

Disclosed is an arrangement for the intrinsically safe detection of movements of a body, such as a wheel.

A primary measuring signal path (S, f) is constructed so that during normal operation represents an output signal the basic frequency of the encoder movement or the temporal profile of the output signal have patterns. The temporal occurrence of the patterns correspond to the basic relative speed between the sensor () and the pole pairs of the encoder () which are detected by the sensor.
