    摘要: Disclosed is a method for determining a switching point in a magnetic sensor array. According to said method, the switching edges in the magnetic sensor array (1) caused by a moved transmitter element (1) are evaluated by the fact that a signal is output when a threshold value is exceeded or is not reached. The output signal (110) of the magnetic sensor array is analyzed within a predefined time slot of the signal range, and an optimal switching point (E, F) regarding the slope (111) and/or the position in the zero crossing zone of the oscillation of the output signal (110) is determined.

    摘要: The invention relates to a diagnostic method for a sensor in a motor vehicle equipped with an internal combustion engine. According to said method, during the operation of the motor vehicle, an output signal of the sensor is analysed to determine whether a maximum value of the output signal falls below a first threshold value and/or whether a minimum value of the output signal exceeds a second threshold value. In the latter case, a signal is sent to a control unit, said signal indicating to the latter that the sensor may deliver incorrect data when the motor vehicle is started again.

    摘要: Disclosed is a method for detection of the movement of an element in relation to a sensor arrangement, wherein signals (7-15) are evaluated according to a pulse transmitter (1) passing in front of a sensor (3,4,5) . The signals (7,8;10,11;13,14) of two sensor elements (4,5) arranged next to each other are determined and the phase-frequency characteristics of the signals (7,8;10,11;13,14) of the individual sensor elements (4,5) and the differential signal (9;12;15) of the individual sensor elements (4,5) are evaluated at right angles to the direction of movement in order to ascertain whether all three signals are in phase for the recognition of vibrations.

    摘要: The invention relates to an acceleration sensor with an oscillating structure that is moveably suspended from a substrate and can be deflected under the effect of acceleration. An oscillating level of the oscillating structure is situated essentially in parallel in relation to a substrate level. The acceleration sensor also comprises evaluation means for detecting a deflection of the oscillating structure, whereby said deflection is caused by acceleration. A deflection movement of the oscillating structure (12) is situated in an essentially vertical manner in relation to the oscillating level (x-, y-level) of the oscillating structure (12). Stopper means (36) limit said movement and can be embodied as a bridge-shaped structure between finger-shaped, moveable electrodes. The bridge-shaped structure supports a fixed, finger-shaped electrode from below. The stopper means can also engage with an annular step of a lateral stopper.

    摘要: The invention relates to a method for detecting the motion, especially speed, of an element relative to a sensor assembly, during which switching signals (1) are evaluated according to a pulse generator that is moved past the sensor, and a switching hysteresis (H) is adapted during the evaluation according to the values of the switching signal (1). In the event a signal frequency is less than a predetermined threshold frequency (flimit), a relatively large hysteresis (Hyst0) is set and in the event a signal frequency exceeds the threshold frequency (flimit), a reduced hysteresis (H1) is set. This makes it possible, when at a standstill and at a low speed, to obtain a high immunity from vibrations and, at a high speed, to obtain a reliable detection of all pulses themselves with a suddenly enlarged air gap.
