Abstract
A shift range control apparatus includes: an idling determination portion that determines, based on a motor angle and an output shaft angle, an end of an idling state in which a motor is rotating within a range of a play, the motor angle being a value based on a detected value of a motor rotation angle sensor that detects the rotation of the motor, the output shaft angle being a value based on a detected value of an output shaft sensor that detects rotation of the output shaft; and a target value setting portion that sets a motor angle target value for drive control of the motor using a corrected angle value that is a value corresponding to the motor angle at an end of an idling.
Claims8
A shift range control apparatus changing shift ranges by controlling drive of a motor in a shift range switching system where a play exists between a motor shaft that is a rotation shaft of the motor and an output shaft to which rotation of the motor is transmitted, the shift range control apparatus comprising:
- an idling determination portion that determines, based on a motor angle and an output shaft angle, an end of an idling state in which the motor is rotating within a range of the play, the motor angle being a value based on a detected value of a motor rotation angle sensor that detects the rotation of the motor, the output shaft angle being a value based on a detected value of an output shaft sensor that detects rotation of the output shaft;
- and
- a target value setting portion that sets a motor angle target value for drive control of the motor using a corrected angle value that is a value corresponding to the motor angle at an end of an idling.
A shift range control apparatus changing shift ranges by controlling drive of a motor in a shift range switching system where a play exists between a motor shaft and an output shaft, the shift range control apparatus comprising:
- at least one processor that is configured to
- determine, based on a motor angle and an output shaft angle, an end of an idling state in which the motor is rotating within a range of the play, the motor angle being a value based on a detected value of a motor rotation angle sensor that detects the rotation of the motor, the output shaft angle being a value based on a detected value of an output shaft sensor that detects rotation of the output shaft, and
- set a motor angle target value for drive control of the motor using a corrected angle value that is a value corresponding to the motor angle at an end of an idling.
