Filed: 1993-11-30
Abstract: PURPOSE:To detect, with good accuracy, a magnetic field generated by an object at the outside of a moving body by correcting a magnetic field due to induction magnetism generated around a ferromagnetic substance (a soft magnetic material) constituting an electronic device which drives a magnetic sensor. CONSTITUTION:A magnetic sensor is arranged in the center of Helmholtz coils which are arranged in three X-, Y- and Z-axis directions crossing orthogonally to each other and which generate uniform magnetic fields. The sensitivity and the orthogonal accuracy of the X-, Y- and Z-axis components are corrected in a state that no ferromagnetic substance exists in the circumference. After that, an electronic device is installed in a prescribed position. Prescribed magnetic fields are applied to the X-, Y- and Z-axes for the sensor. Correction factors A to I are found. The relationship between the magnetic fields X, Y, Z applied to the individual axes and correction outputs (x), (y), (z) is incorporated in a microcomputer for the electronic device and software on the basis of a relational expression. Induction magnetism is corrected and detected. Thereby, even when the sensor which is arranged so as to be close and the ferromagnetic substance for the electronic device are moved integrally in terrestial magnetism, it is possible to detect a magnetic field in which the induction magnetism generated by the ferromagnetic substance and a magnetic field due to a permanent magnet have been corrected.
