To provide a steering system that is able to improve real-time performance for a to-be-detected steering torque and also able to inhibit complication of a structure while ensuring redundancy.SOLUTION: A steering system 1 comprises: a priority torque sensor 32 and a redundant torque sensor 33 that respectively detect steering torques Th1 and Th2; and a control device 3 that controls an operation of a motor 21 on the basis of the steering torques Th1 and Th2. The priority torque sensor 32 and the control device 3 are connected by a first signal line L1 that transmits a first priority detection signal Sy1 including a digital value Dy1 output by a first priority detection unit 91, and by a second signal line L2 that transmits a second priority detection signal Sy2 including a digital value Dy2 output by a second priority detection unit 92. The redundant torque sensor 33 and the control device 3 are connected by a common signal line Lc that transmits a first redundancy detection signal Sj1 and a second redundancy detection signal Sj2 including digital values Dj1 and Dj2 output by a first redundancy detection unit 101 and a second redundancy detection unit 102, respectively.SELECTED DRAWING: Figure 2

    【課題】検出する操舵トルクのリアルタイム性を高めるとともに、冗長性を確保しつつ構造の複雑化を抑制できる操舵システムを提供する。【解決手段】操舵システム1は、操舵トルクTh1,Th2をそれぞれ検出する優先トルクセンサ32及び冗長トルクセンサ33と、操舵トルクTh1,Th2に基づいてモータ21の作動を制御する制御装置3とを備える。優先トルクセンサ32と制御装置3とは、第1優先検出部91が出力するデジタル値Dy1を含む第1優先検出信号Sy1を送信する第1信号線L1、及び第2優先検出部92が出力するデジタル値Dy2を含む第2優先検出信号Sy2を送信する第2信号線L2により接続され、冗長トルクセンサ33と制御装置3とは、第1冗長検出部101及び第2冗長検出部102がそれぞれ出力するデジタル値Dj1,Dj2を含む第1冗長検出信号Sj1及び第2冗長検出信号Sj2を送信する共通信号線Lcにより接続される。【選択図】図2
