摘要： The rotation angle detection apparatus comprises: a rotor connected to a rotating body, a rotation angle detection unit, a memory unit and a control unit. Control unit detects an amplitude absolute value of a first angle detection signal and amplitude absolute value of a second angle detection signal. Control unit compares detected amplitude absolute value of first angle detection signal and amplitude absolute value of second angle detection signal to determine which is a smaller amplitude absolute value or a larger amplitude absolute value. Control unit calculates a basic rotation angle of the rotating body based on an arctangent angle of a quotient value obtained by dividing the smaller amplitude absolute value by the larger amplitude absolute value. Control unit converts the basic rotation angle to a different angle value for each of a plurality of angle processing cases, and the rotation angle of the rotating body is detected.

摘要： A rotation angular speed detection apparatus that accurately detects a low rotation angular speed of a rotating body includes: a receiving part for receiving rotation angles at predetermined time intervals from a rotation angle sensor that detects rotation angles of a rotating body; a storage part for storing received rotation angles; and a control part. When the difference between a first arbitrary angle stored and a second angle stored before the first angle is less than a predetermined value, the control part determines, from the stored rotation angles, a third angle in which a difference between the first angle and the third angle is more than the predetermined value, and the control part divides the difference between the first angle and the third angle by the time required from storing of the third angle to storing of the first angle to detect a rotation angular speed.

摘要： A rotational angle detecting device includes a rotation detecting section for outputting sinusoidal first and second detection signals as a result of the rotation of a rotor connected to a rotary member, a storage section for updating and storing the first and second detection signals, and a controlling section. The first and second detection signals have constant amplitudes, have the same periods, and have wavelengths which are output of phase. The controlling section compares the amplitude values of most recent first and second detection signals output from the rotation detecting section, and determines whether or not the amplitude values fall within proper ranges. When the controlling section determines that they fall within the proper ranges, a piece of detection information which is created based on the most recent first and second detection signals is supplied to a controller. On the other hand, when the controlling section determines that they do not fall within the proper ranges, the controlling section destroys the most recent first and second detection signals, and does not supply detection information to the controller. The invention provides a rotational angle detecting device for performing required controlling operations using detection signals output from the rotational detecting section which have been determined as being proper detection signals.
