Abstract:
1. A torque detection apparatus comprising: a sensor unit which outputs a signal corresponding to a torque generated at a rotary shaft and a torque sensor circuit which detects the torque generated at the rotary shaft based upon the signal output from the sensor unit, the torque sensor circuit comprising: a signal processing unit which detects an analog main torque signal and an analog sub torque signal based upon the signal output from the sensor unit; an AD converter which converts the analog main torque signal and the analog sub torque signal detected by the signal processing unit to digital values of a main torque value and a sub torque value; a monitoring unit which monitors for an abnormality of the signal processing unit; and a communication output unit which outputs a digital communication signal in which the main torque value and sub torque value converted by the AD converter and diagnosis information including the abnormality diagnosis results by the monitoring unit are superimposed.
