A rotational angle sensor system including: a rotatably mounted movement sensor; a sensor that is designed to detect a rotation of the movement sensor, wherein the rotation occurs at a measurement angle interval; an evaluation electronics system designed to receive an analogue signal from the sensor and to digitalise same using an internal resolution, and to emit a digital output signal reporting the rotation detected by the sensor, wherein the resolution of the digital output signal for a measurement angle interval of less than or equal to 360&#xb0; is the same size as the internal resolution.

Rotation angle sensor system with variable measurement angle range

A signal processing device for processing a measurement signal in a motor vehicle, wherein the measurement signal relates to a measurement variable which can change over time with sequential measurement values, including: a first signal processing unit for calculating the measurement variable which can change over time from the measurement signal; a second signal processing unit for processing the measurement variable which can change over time in order to obtain a processed measurement variable; a third signal processing unit for calculating a change rate of the measurement variable which can change over time, the third signal processing unit being designed to output an additional measurement signal which indicates the change rate; and a communication interface which is designed to combine the processed measurement variable and the additional measurement signal into a composite transmission signal and to transmit the composite transmission signal.

A method for checking the plausibility of a measurement result for an electric current by a current sensor connected to an electrical circuit, the method including: making a predetermined change to the switching state of the electrical circuit; detecting, by the current sensor, a change to the electric current resulting from the change to the switching state as a measurement result; and checking the plausibility of the measurement result by contrasting the change to the switching state and the change to the electric current.

Method and circuit for checking the plausibility of a current sensor measurement result

Sensor () and method for the detection of the movement of an encoder to be monitored with at least two sensor elements (), which are arranged in a way offset relative to each other in the direction of movement of the encoder, and with a processing circuit (), which converts the element output signals (S, S) at the outlets of the sensor element () to a sensor output signal (S) that describes the movement of the encoder, with the processing circuit () including a test circuit (), which monitors the element output signals (S, S) at least indirectly and disables or corrects the sensor output signal (S) when errors of the element output signals () are detected.

Sensor and method for the detection of local displacements and rotations

Active sensor for switching over into a special operating mode, wherein the sensor has at least one sensor element, one evaluation circuit and two connecting lines, each with a terminal for transmitting the sensor information, wherein a supply voltage of the sensor is applied to the two connecting lines, wherein the sensor comprises a switchover module with which it is possible to switch over between a normal operating mode and a special operating mode by reversing the polarity of the supply voltage which is applied to the two terminals. A method for actuating an active sensor and to the use of the sensor, in particular as a wheel speed sensor, in motor vehicles.
