ABSTRACT:
A torque detector, for detecting a torque applied to a torque transmission shaft which is connected to a load of an automobile, comprises an elastic member which is interposed between a driving shaft and the torque transmission shaft so as to be connected thereto, rotating members, each of which is integrally provided with the shafts, have a plurality of teeth or notches in the outer periphery thereof so as to be positioned in each combustion stroke of each piston of an engine of the automobile, electromagnetic pickups for detecting the passing of the teeth or notches and a data processing circuit for calculating torque at a predetermined rotating angle from the angular phase difference between the above two shafts, the torque occurring due to the deformation of the elastic member caused by the increase or decrease of applied torque. The processing means adds the calculated torque in each combustion stroke of each piston and averages the added torque.
