Title:
移動する物体の絶対的な位置特定のための方法及び装置
Document Type and Number:
Japanese Patent JP5613839
Kind Code:
B2
Abstract:
In a device for determining absolute position of a mobile element in reference to two magneto-sensitive sensors, having a source of a magnetic field fastened to the element, a first sensor signal and a second sensor signal are measured with one magneto-sensitive sensor each. An amplitude ratio of the respective sensor signals and the off-set values about the respective zero point of the sensor signals are determined from the minimum and maximum values of the sensor signals, and from these values, scaled sensor signals are calculated that form a sum signal and a difference signal, which are scaled, with the determination of the minimum and the maximum values occurring by a relative movement of the element over a full range of motion, and an absolute position is calculated via the scaled sum signal and the scaled difference signal.
