摘要： PROBLEM TO BE SOLVED: To easily reduce a residual torque to a level not hindering steering control, without requiring technical skill and long time regulation, to reduce a cost, and to stabilize performance.
SOLUTION: When a trigger signal is input, a CPU 31 reads an initially set program from a ROM 33, and executes following procedures. (1) The first torque value including the residual torque is detected in the first position where a steering wheel 1 is rotated by a prescribed angle along one direction around a steering wheel axial line from a neutral position, using an assist motor 20, to be stopped there. (2) The second torque value including the residual torque is detected in the second position where the steering wheel 1 is rotated by the same angle along the other direction from the neutral position, to be stopped there. (3) An average value of the first and second torque values is found to offset the negative and positive residual torques, and the average value is determined as an initial torque due to a difference between origin positions of a paired resolvers 12, 12. (4) The initial torque is stored as a correction value for a steering torque in a data storage area 33b.

摘要： PROBLEM TO BE SOLVED: To reduce a working cost and an assembling cost.
SOLUTION: An outer circumference of a cylindrical magnetism leakage preventing member 12 made of a nonmagnetic material covering an outer circumference of the first shaft 3 made of a magnetic material is covered with the first detection cylinder 13 made of a magnetic material. The second detection cylinder 14 made of a magnetic material is rotated along with the second shaft connected elastically and relatively rotatably to the first shaft 3, and one end thereof is opposed to one end of the first detection cylinder 13 with a clearance therebetween. Magnetic resistance against a passing magnetic flux in the first magnetic circuit constituted by generating a magnetic flux passing through the one end of the first detection cylinder 13 and the one end of the second detection cylinder 14 by the first coil 16 is changed in accordance with an elastic relative rotational amount by transmission torque changes of the both shafts 3, 4. The magnetism leakage preventing member 12 is molded of a synthetic resin injected in a molding die. The first and second shafts 3, 4 are integrated to be rotated along with the magnetism leakage preventing member 12 die-molded by inserting the shafts 3, 4 into the molding die before the injection of the synthetic resin.
