摘要： In a torque sensor of a torque detection system, in a state where a torque is not generated, a first magnetic detector (61) overlaps with one, such as an N-pole, of a plurality of magnetic poles of a magnet (30) when the one of the plurality of magnetic poles of the magnet (30) is radially projected onto the first magnetic detector (61). A second magnetic detector (62) overlaps with another one, such as an S-pole, of the plurality of magnetic poles when the another one of the plurality of magnetic poles is radially projected onto the second magnetic detector (62). A motor control device, which corresponds to a calculation processor of the torque detection system, is configured to calculate a sum of a value, which relates to a detected strength of a magnetic field detected by the first magnetic detector (61), and a value, which relates to a detected strength of the magnetic field detected by the second magnetic detector (62). The motor control device is configured to calculate a steering torque based on the sum.

摘要： An on-vehicle detector (1) includes a torque detecting portion (2) for magnetically detecting a torque transmitted to a rotating shaft (11) rotated by steering operation, and a rotation detecting portion (3) for magnetically detecting a rotation of the rotating shaft (11). The rotation detecting portion (3) includes a magnet (33) with a pair of magnetic poles and a magnetic detection element (34), the magnet (33) being disposed on a side of the rotating shaft (11) so as to rotate simultaneously with the rotating shaft (11) and the magnetic detection element (34) being disposed on a side of the vehicle to detect a change in magnetic flux density caused by the magnet (33) approaching or moving away in accordance with the rotation of the rotating shaft (11). The magnet (33) is disposed such that the pair of magnetic poles is aligned along a circumferential direction of the rotating shaft (11).
