Abstract
Disclosed is a power steering system which involves no dedicated equipment, no increase in cost, and no such hardware operation for correction as the mounting of an adjusting resistor. The power steering system includes an external device which outputs an arbitrary torque signal in an error measurement mode, and an electric power steering control device which detects the torque signal, computes the differential between the detected torque value and a reference torque value, stores the differential as a torque correction value, and, in the actual control mode, uses the detected torque value after correcting it by the torque correction value, whereby it is possible to perform reading error correction on a software basis and to expedite and automate the correction.
