    • The rotation angle detection device of the present invention contains i) a rotation detecting body; ii) a first rotator engaging with the rotation detecting body; iii) a second rotator engaging with the first rotator; iv) a first detector that detects the rotation angle of the first rotator; v) a second detector that detects the rotation angle of the second rotator; and vi) a self-evaluating section. Referencing to the output range of the first and the second signals detected by the first and the second detectors under the normal condition of the rotation detecting body, the self-evaluating section determines, through calculation of the output range of the signals, the normal condition and the abnormal condition ranges. When at least one of the values of the signals is in the abnormal condition range, the self-evaluating section judges that the rotation detecting body is in an abnormal operation.

    • The rotation-angle detecting device of the present invention contains two rotators having the same number of teeth, which engage with a gear fixed to a rotation-detecting axle as a detected object. The detecting device further includes a controller. Receiving a rotation-angle signal from the rotators, the controller amplifies the signal, performs calculations, and stores the results. The controller converts each rotation-angle signal from each rotator into each periodic waveform output having the same crest value, and stores an initial phase difference value at initial setting. In driving operations, monitoring an evaluation value calculated with reference to the initial phase difference value, the controller determines that abnormalities occurred, if the evaluation value exceeds a predetermined abnormality-evaluation threshold.
    • 本发明的旋转角度检测装置包括具有相同齿数的两个旋转器,所述两个旋转器与固定到作为检测对象的旋转检测轴的齿轮啮合。 该检测装置还包括控制器。 从旋转器接收旋转角度信号,控制器放大信号,执行计算并存储结果。 控制器将来自每个旋转器的每个旋转角度信号转换为具有相同峰值的每个周期性波形输出,并且在初始设置时存储初始相位差值。 在驾驶操作中,监视参考初始相位差值计算的评估值,如果评估值超过预定的异常评估阈值,则控制器确定发生了异常。
