ELECTRICALLY-DRIVEN POWER STEERING DEVICE, ADJUSTING DEVICE OF ELECTRICALLY-DRIVEN POWER STEERING DEVICE AND ADJUSTING METHOD OF ELECTRICALLY-DRIVEN POWER STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrically-driven power steering device which improves accuracy in both of an assist control and a control other than the assist control.;SOLUTION: An electrically-driven power steering device has, as output signals of a torque sensor, a first output signal for use in an assist control and a second output signal for use in a control other than the assist control. An adjusting device 50 comprises: an input torque measuring instrument 55 that measures input torque applied to an input shaft 11; an output torque measuring instrument 52 that measures output torque output by a steering mechanism 3; and a sensor output corrector 54 that corrects output signals of the torque sensor 2. The sensor output corrector 54 corrects the first output signal so that a relation between the input torque measured by the input torque measuring instrument 55 and the output torque measured by the output torque measuring instrument 52 exhibits a predetermined ideal characteristic, and corrects the second output signal so that input torque detected by the torque sensor 2 coincides with the input torque measured by the input torque measuring instrument 55.;COPYRIGHT: (C)2014,JPO&INPIT
