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.

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.

The first and fifth GMR devices, and the second and sixth GMR devices are disposed in a symmetrical manner as to the point of origin, and accordingly the intensity and direction of an external magnetic field applied from a rotating magnet is the equal between the first and fifth GMR devices, and also equal between the second and sixth GMR devices.

摘要： A magnetic switch hardly affected by an external magnetic field even if a cheap magnet is used and capable of performing magnetic detection for a long period of time is provided. A first magnetic path L1 and a second magnetic path L2 in which a stationary rail 13 and a movable rail 14 lead magnetic fluxes are formed in a non-shielding state where magnetism shielding 18 is not interposed in a gap G between a magnet M and a Hall element H to secure the number of magnetic fluxes that pass through the Hall element H. Therefore, it is not necessary to use a costly rare earth magnet having a large number of generated magnetic fluxes. In n shielding state where the magnetism shielding 18 is interposed in the gap G, the first magnetic path L1 is shielded. As a result, the number of magnetic fluxes that pass through the Hall element H is almost zero. Since the magnet M and the Hall element H are covered with the stationary rail 13 and the movable rail 14, the magnetic switch is hardly affected by the external magnetic field.

摘要： The absolute angle of the rotation angle is detected on the basis of a first detection signal including sawtooth continuous pulses and a second detection signal that rises stepwise. The second detection signal includes a plurality of flat portions and a plurality of gradually rising portions that link the flat portions, corresponding to the pulses of the first detection signal. Each gradually rising portion corresponds to the sharply falling portion of the first detection signal. When the value of the second detection signal is included in a flat portion, the absolute angle is found based on the first and second detection signals, and, when the value of the second detection signal is included in a gradually rising portion, the absolute angle is found based on the first detection signal in conjunction with the second detection signal corresponding to a flat portion preceding or following the gradually rising region.
