    摘要: A method for determining the angular position of a rotating object and rotary encoder is disclosed. In one embodiment, the method includes a method for determining the angular position of an object rotating about a rotation axis in a rotation direction and having a coding pattern, using a sensor that senses the coding pattern, including ascertaining the coarse angular position of the rotating object with respect to the sensor whilst taking account of the coding pattern at a first instant. The exact angular position of the rotating object is ascertained with respect to the sensor whilst taking account of the coarsely ascertained angular position and also whilst taking account of at least one section of the coding pattern which extends counter to the rotation direction proceeding from that location of the coding pattern which is assigned to the coarse angular position. An output signal is provided containing items of information about the exact angular position of the rotating object with respect to the sensor.

    摘要: A method for evaluating a sensor signal provided by a magnetic field sensor which is arranged at a distance from an object which is rotatable about an axis of rotation. The method includes defining an encoding pattern with a sequence of symbols, the sensor signal being dependent on the encoding pattern and at least one transmission parameter; regenerating the symbols of the encoding pattern from a corrected sensor signal using a threshold value detector to obtain an output signal; generating a filtered signal from the output signal using a filter having a plurality of filter coefficients; superposing the sensor signal and the filtered signal to obtain the corrected sensor signal; and wherein the corrected sensor signal and the output signal are used to estimate the at least one transmission parameter, and the filter coefficients are derived from the estimated transmission parameter.
