Abstract
A method for zero correction in torque sensors, such as magnetostrictive torque sensor and strain gauge type torque sensor. Torque measurement is initiated when absolute values of torque signals are greater than a first set value, sampling measurement is carried out at predetermined intervals after the initiation. After absolute values of the measured torque signal values become lower than a second set value, an average value for a predetermined number of torque signal values whose absolute values are lower than a third set value is set as a new zero. The method permits proper measurement and correction of zero signals from torque sensors employed succesively at locations subject to impulse-like action of a torque load.
