Title:
回転レートを求めるための装置
Document Type and Number:
Japanese Patent JP4571715
Kind Code:
B2
Abstract:
A device which determines a motion parameter with a sensor having a plurality of sensor elements coupled to one another, in which the motion parameter corresponds to a rotational speed. The device includes a starter loop for putting the sensor in a state of excitation via a starter signal via at least one of the sensor elements and for generating a sensor quantity, with the sensor quantity being a measure of a response of the sensor to the starter signal, and the starter signal having a substantially constant amplitude. A detector loop coupled to at least one of the sensor elements is also provided in the device for providing a measurement signal correlating with the motion parameter. The device further includes an analysis unit for providing an output voltage representing the motion parameter as a function of the measurement signal, a correction unit for keeping a substantially constant correlation between the output voltage and the motion parameter and for generating a correction signal as a function of the sensor quantity, and a multiplier providing the correction signal to the analysis unit.
