The invention discloses a steering angle calculation method and a steering angle sensor based on redundancy design, and the steering angle calculation method based on redundancy design comprises the steps: combining the rotation angle measurement data of a plurality of driven gears in pairs, calculating different combinations through a double-gear difference calculation formula, and calculating the rotation angle measurement data of the driven gears; acquiring first rotation angle data of the driving gear corresponding to the combination; the first rotation angle data of the different driving gears are substituted into a driven gear rotation turn number calculation formula, and the corresponding driven gear rotation turn number is obtained; and performing difference operation on the first rotation angle data of different driving gears, combining difference operation results into a column vector, and calculating the infinity norm of the column vector as a judgment identifier. According to the invention, the problem that the output rotation angle data is wrong because the rotation angle sensor of multiple driven gears at present cannot carry out identification and troubleshooting and cannot provide accurate rotation angle information when the driven gears are worn, stuck and other faults is solved.

    本发明公开了一种基于冗余设计的转向转角计算方法及转角传感器,其中一种基于冗余设计的转向转角计算方法,包括:将多个从动齿轮的转动角度测量数据进行两两组合,通过双齿轮差值计算公式计算不同组合,获取与组合相对应的主动齿轮第一转角数据;将不同主动齿轮第一转角数据带入从动齿轮旋转圈数计算公式,得到对应从动齿轮旋转圈数;将不同主动齿轮第一转角数据进行差值运算,并将差值运算结果组合为列向量,并计算列向量的∞范数,作为判断标识等步骤。本发明有助于解决目前多从动齿轮的转角传感器在从动齿轮出现磨损、卡死等故障时,不能进行识别和排查,无法提供准确的转角信息,使得输出转角数据有误的问题。
