Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/179337
Kind Code:
A1
Abstract:
This shift range control device switches shift range by controlling the drive of a motor (10). The shift range control device comprises a feedback control unit (52) that performs position feedback control on the basis of a target angle determined according to the requested shift range and the actual angle of the motor; a fixed phase ON/OFF control unit (61) that performs fixed phase ON/OFF control that provides power to a fixed phase selected according to an actual angle; and a switching control unit (65) that switches between motor control states. The switching control unit switches the control state to position feedback control when the requested shift range is switched. If the difference between the target angle and the actual angle drops to or falls below an angle determination threshold, the switching control unit switches the control state from position feedback control to fixed phase ON/OFF control.
