신뢰성이 높은 토오크 검출 장치, 그 토오크 검출 장치를 사용한 전동 파워 스티어링 장치 및 차량을 제공한다. 토오크 검출 장치(30)는, 한 쌍의 검출 코일의 단자 전압의 차분(差分)에 근거하여 토오크를 검출한댜. 이때, 토오크 검출 장치(30)는, 2 개의 아날로그 토오크 신호(아날로그 메인 토오크 신호(Tma)와 아날로그 서브 토오크 신호(Tsa))를 ECU(15)에 출력하는 동시에, 2 개의 아날로그 토오크 신호를 디지털화 한 디지털 토오크치(메인 토오크치(Tm)와 서브 토오크치(Ts)와, 토오크 센서 회로의 진단 정보(Diag)를 중첩한 디지털 통신 신호(S)를 ECU(15)에 출력한다.

    There are provided a torque detection apparatus with high reliability and an electric power steering system and a vehicle which use the torque detection apparatus. The torque detection apparatus (30) detects the torque based upon a difference in the terminal voltage of the pair of detection coils.. In this situation, the torque detection apparatus (30) outputs two analog torque signals (analog main torque signal Tma and analog sub torque signal Tsa) to the ECU (15), and outputs to the ECU (15) a digital communication signal S in which digital torque values obtained by converting the two analog torque signals to a digital format (main torque value Tm and sub torque value Ts) and diagnosis information Diag of the torque sensor circuit are superimposed.
