Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/049995
Kind Code:
A1
Abstract:
In the present invention an angle calculation unit (51) calculates a motor angle on the basis of a motor rotation angle signal obtained from a motor rotation angle sensor (13) that detects the rotational position of a motor (10). An acceleration variation calculation unit (51) calculates an acceleration variation parameter related to an amount of variation in the motor acceleration, on the basis of the motor angle. An idling determination unit (52) determines the end of an idling state in which the motor (10) is rotating within the range of play, on the basis of the acceleration variation parameter. A target setting unit (55) sets a target motor angle by using an angle correction value, which is a value in accordance with the motor angle when the idling state ends. A drive control unit (56) controls driving of the motor (10) such that the motor angle becomes the target motor angle.
