To provide an angle calculation device that can propose the unprecedented use of an absolute angle calculated redundantly, and provide a steering device.SOLUTION: A steering control unit 47 includes a first count value arithmetic circuit 50, a second count value arithmetic circuit 60, a first absolute angle arithmetic circuit 70, a second absolute angle arithmetic circuit 80 and a control device 90. The control device 90 calculates a first integrating angle by using a first count value C1 calculated by the first count value arithmetic circuit 50, calculates a first absolute angle by using absolute angle information calculated by the first absolute angle arithmetic circuit 70, and calculates a second absolute angle by using the absolute angle information calculated by the second absolute angle arithmetic circuit 80. The control device 90 has a determination unit for determining the presence or absence of abnormality of the first absolute angle and the second absolute angle on the basis of the relationship between the first absolute angle and the first integrating angle, and the relationship between the second absolute angle and the first integrating angle.SELECTED DRAWING: Figure 2

    【課題】冗長して演算された絶対角のこれまでにない新しい用途を提案することのできる角度演算装置及び転舵装置を提供する。【解決手段】転舵制御部47は、第1カウント値演算回路50と、第2カウント値演算回路60と、第1絶対角演算回路70と、第2絶対角演算回路80と、制御装置90とを備えている。制御装置90は、第1カウント値演算回路50により演算された第1カウント値C1を用いて第1積算角を演算し、第1絶対角演算回路70により演算された絶対角情報を用いて第1絶対角を演算し、第2絶対角演算回路80により演算された絶対角情報を用いて第2絶対角を演算する。制御装置90は、第1絶対角及び第1積算角の関係と、第2絶対角及び第1積算角の関係とに基づいて、第1絶対角及び第2絶対角の異常の有無を判定する判定部を有している。【選択図】図2
