An apparatus for detecting a failure of a steering angle sensor according to one embodiment includes: a steering angle sensor including a main gear rotating together with a steering wheel, the steering angle sensor rotating together with the steering wheel while having a predetermined gear ratio with respect to the main gear; the first auxiliary gear and the second auxiliary gear are respectively meshed with the main gear; the first Hall IC chip is used for detecting the angle of the first auxiliary gear; the second Hall IC chip is used for detecting the angle of the second auxiliary gear; and a control unit. Determining a failure of the steering angle sensor from a first angular difference between a current point in time and a past point in time of a first pinion angle detected by the first Hall IC chip and a second angular difference between a current point in time and a past point in time of a second pinion angle detected by the second Hall IC chip .

    根据一个实施例的转向角传感器的故障检测装置包括:转向角传感器,包括与方向盘一起旋转的主齿轮、在与所述主齿轮具有预定齿轮比的同时,分别啮合到所述主齿轮的第一副齿轮和第二副齿轮以及检测所述第一副齿轮的角度的第一霍尔IC芯片和检测所述第二副齿轮的角度的第二霍尔IC芯片;以及控制部,根据通过所述第一霍尔IC芯片来检测的第一副齿轮角度的当前时间点和过去时间点之间的第一角度差以及通过所述第二霍尔IC芯片来检测的第二副齿轮角度的当前时间点和过去时间点之间的第二角度差来判断所述转向角传感器的故障。
