Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/142576
Kind Code:
A1
Abstract:
A motor angle computing unit (51) acquires from a motor rotation angle sensor (13) that detects rotation of a motor (10) a motor rotation angle signal corresponding to a rotational position of the motor (10), and computes a motor angle on the basis of the motor rotation angle signal. An output shaft signal acquisition unit (52) acquires, from an output shaft sensor (16) that detects a rotational position of an output shaft (15) to which the rotation of the motor (10) is transmitted, an output shaft signal corresponding to the rotational position of the output shaft (15). An abnormality determination unit (53) determines abnormality in the output shaft sensor (16). A target angle setting unit (54) sets a target rotation angle corresponding to a target shift range. A drive control unit (55) controls driving of the motor (10) so that the motor angle becomes a target rotation angle. The target angle setting unit (54) sets the target rotation angle to different values when the output shaft sensor (16) is normal and when the output shaft sensor (16) is abnormal.
