Abstract
Official abstract text for this publication.
An angle detection device includes: first and second rotation measuring instruments; an anomaly detection unit detecting occurrences of anomalies in the first and second rotation measuring instruments; and a switching interpolation unit configured to select a first angle signal and a first angular speed signal and output as a third angle signal and a third angular speed signal when the first rotation measuring instrument is normal, and to perform switching so that a second angle signal and a second angular speed signal are output as the third angle signal and the third angular speed signal while performing interpolation so that the difference between the first angle signal and the second angle signal is reduced stepwise if the second rotation measuring instrument is normal when an anomaly has occurred in the first rotation measuring instrument.
First claim
Opening claim text (preview).
What is claimed is: 1 . An angle detection device comprising: a first rotation measuring instrument configured to output a first angle signal and a first angular speed signal related to a rotation angle of a rotating body; a second rotation measuring instrument configured to output a second angle signal and a second angular speed signal related to the rotation angle of the rotating body; an anomaly detection unit configured to monitor signals in the first and second rotation…
