method and device of measuring the maximum and minimum values, torque gauge and steering with the device for the measurement of maximum and minimum values

摘要

The method and apparatus for detecting maximum and minimum values, and the torque detecting apparatus and steering apparatus comprising the maximum and minimum values detecting apparatus can detect maximum and minimum values of detection signals without setting a particular value such as a threshold. A signal processing unit (20) provided at the maximum and minimum values detecting apparatus detects a crossing of two detection signals outputted from two MR sensors (1,2), and detects maximum and minimum values of the signals based on maximum and minimum values of the signals detected within a time interval defined by the time when a crossing is detected.
