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