Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/155332
Kind Code:
A1
Abstract:
A shift range control device (40) that switches shift ranges by controlling the drive of a motor (10) and comprises a first switching control unit (71), an inversion control unit (76), and a second switching control unit (77). The first switching control unit (71) switches from feedback control to stationary duty control, when the difference between the target angle and actual angle at which the motor (10) is stopped is less than an angle determination threshold value. An inversion determination unit (76) determines that the motor (10) is inverted. The second switching control unit (77) switches from stationary duty control to stationery phase ON/OFF control whereby current is supplied to the stationery phase of the motor (10), when a determination has been made that the motor (10) is inverted.
