Abstract: In a method of determining residual error compensation parameters for a magnetoresistive angle sensor providing a first measurement signal depending on a rotational angle the step of generating a plurality of value pairs for a plurality of rotational angle values is provided, wherein each value pair has a rotational angle value and an associated measurement signal value. The method further includes ascertaining a sinusoidal fit function the course of which is adapted to the plurality of value pairs. Finally, residual error compensation parameters can be generated from a difference between the ascertained sinusoidal fit function and the associated measurement signal values of the measurement signal for the plurality of rotational angle values.

Abstract: 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.

The sensor cell provides a sensor cell output signal depending on a physical magnitude to be detected which is changed in means for changing the sensor cell output signal according to a predetermined change regulation based on a test signal in order to obtain the sensor signal. A signal derived from the sensor signal is detected by a device for an in-operation test of the signal path and is evaluated.

Abstract: The present disclosure is directed towards a sensor interface module that delivers a supply voltage to a plurality of sensors, and which exchanges data signals between the plurality of sensors and a control unit (e.g., an ECU). The sensor interface often employs a single-bit comparator (or a coarse analog to digital converter (ADC), e.g., a 2-bit or 3-bit ADC) to track signals to be exchanged between the sensors and controller over the sensor interface. Compared to power hungry ADC with more bits (e.g., 32 bit ADC), the single-bit comparator/coarse ADC limits hardware complexity and power consumption. In addition, in some embodiments the sensor interface module can include an estimator and assist comparators to speed up the tracking ability of the sensor interface module. In this way, techniques provided herein facilitate reliable, low-power communication between a control unit (e.g., an ECU) and its corresponding sensors.
