Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047916
Kind Code:
A1
Abstract:
A shift range control device (40) that comprises a feedback control unit (60), a feedback value setting unit (63), a fixed-phase electrification control unit (70), and a switching control unit (75). The feedback control unit (60) performs feedback control that is based on the actual angle of a motor (10) and on a motor speed that is the rotational speed of the motor. The feedback value setting unit (63) sets a feedback value for the motor speed on the basis of the motor speed such that the phase of the motor speed advances. The fixed-phase electrification control unit (70) performs fixed-phase electrification control that causes electrification at a fixed phase that is selected on the basis of the actual angle of the motor. The switching control unit (75) sets control of the motor to feedback control when requested shift range has been switched and, when an angle deviation that is the difference between the actual angle of the motor and a target angle for the motor that is decided on the basis of the requested shift range is at or below an angle determination threshold, switches control of the motor from feedback control to fixed-phase electrification control.
