Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/230462
Kind Code:
A1
Abstract:
A shift range control device (40) comprising an angle calculation unit (51), a target angle setting unit (55), a learning unit (52), and a drive control unit (56). On the basis of a motor angle and an output shaft signal, the learning unit (52) learns a correction value to be used in calculating a motor angle target value. The learning unit (52) learns the correction value on the basis of a first change point value, which is the motor angle at a timing at which the output shaft signal changes when a rotation member (21) rotates in a first direction from a state in which an engagement member (26) is in the center of recessed sections (221-224), and/or a second change point value, which is the motor angle at a timing at which the output shaft signal changes when the rotation member (21) rotates in a second direction from a state in which the engagement member (26) is in the center of the recessed sections (221-224).
