Title:
DETECTION SIGNAL CORRECTION METHOD, MOTOR CONTROL DEVICE, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/250917
Kind Code:
A1
Abstract:
This detection signal correction method comprises: calculating a rotation angle of a rotation shaft of a motor (10) on the basis of a detection signal of a sensor (20) (S1); calculating a steering speed of a steering shaft on the basis of the rotation angle (S2); calculating an error of the detection signal (S5); and correcting the error of the detection signal when the steering speed is equal to or greater than a steering speed threshold value and the error of the detection signal is equal to or greater than an error threshold value (S7, S9).
