Abstract: In a method of operating a brake assistant system which includes a first mode of operation in which the brake assistant system is not operated, a second mode of operation in which, after recognition of an emergency brake situation, a pressure build-up of wheel brakes is generated, and a third mode of operation which is provided for the transition from the second into the first mode of operation, wherein in the third mode of operation the wheel brake pressure (pWHEEL) is excessively elevated compared to the tandem master cylinder pressure (pTMC) in a controlled way, a particularly safe and user-friendly termination of the brake assistant system results from diminishing the amount of the excess elevation over the course of time.

Abstract: In a method for the detection of local displacements and rotations, a sum signal and additionally a difference signal are formed from two separately generated signals of two transducer elements (W1, W2), which are spaced from each other, and subsequently the formed sum signal and the formed difference signal are OR-operated. A device for doubling the local frequency of moving incremental scales comprises an encoder (1a, 1b, 1c), a magnetically sensitive transducer (9, 13), and a signal conditioning stage (6a, 6b) electrically connected thereto. The transducer comprises at least two sensorially active functional groups synchronously using sensorially active groups or sub-groups (W1, W2) which are locally offset in relation to each other by a local phase ? in order to scan the moving scale, and the functional groups comprise means enabling at least two independent partial signals S1=V*sin(?t) and S2=?V*sin(?t)+?) to be produced.

Abstract: The present invention relates to a system for detecting safety-critical measured quantities, in particular yaw rates or acceleration data in automotive vehicles, comprising at least two independent measuring channels with sensors that are independent of one another and elements for verifying a malfunction or a failure of the measuring channels. The first measuring channel and the additional measuring channel(s) are operated in hot redundancy employing sensors of the similar type but not exactly identical in such a manner that the sensors are operated in parallel and without restriction. This invention also relates to a device consisting of a sealed housing with a plug, and the aforementioned system is accommodated in the sealed housing.
