Patent number: 11708896Abstract: A shift range control device switches a shift range by controlling driving of a motor. A learning unit learns, as a position correction value, a normal state time correction value calculated based on first and/or second reference angles when an output shaft signal is available when turning on of a start switch. The first reference angle is a motor angle when the output shaft signal changes in response to the rotation of the motor in a first direction. The second reference angle is the motor angle when the output shaft signal changes in response to the motor rotation in a second direction opposite to the first direction. A motor angle target value is set by using the normal state time correction value stored during a period from when all the output shaft signals are determined to be unavailable to when the start switch is turned off.Type: GrantFiled: November 13, 2019Date of Patent: July 25, 2023Assignees: DENSO CORPORATION, HONDA MOTOR CO., LTD.Inventors: Shigeru Kamio, Masahiko Akiyama, Masashi Misawa, Kenshi Masuo

Patent number: 11603927Abstract: A shift range control apparatus controls a shift range switching system that switches shift ranges by controlling driving of a motor. This control apparatus calculates a motor angle based on a motor rotation angle signal, acquires an output shaft signal based on a rotation position of an output shaft from an output shaft sensor, sets a target rotation angle based on a target shift range and the output shaft signal, and controls driving of the motor such that the motor angle becomes the target rotation angle. The control apparatus sets the target rotation angle to a target limit value, in response to the target rotation angle that is set based on the output shaft signal being a value at which rotation occurs that is further toward a back side in a rotation direction than the target limit value that is set based on shift ranges before and after switching.Type: GrantFiled: September 4, 2020Date of Patent: March 14, 2023Assignees: DENSO CORPORATION, HONDA MOTOR CO., LTD.Inventors: Koji Sakaguchi, Masahiko Akiyama, Masashi Misawa, Kenshi Masuo

Patent number: 11396942Abstract: A shift range control device includes a signal receiver, an abnormality monitor, and a drive controller. The signal receiver acquires an encoder signal from an encoder capable of outputting three or more phase encoder signals having different phases. The abnormality monitor monitors an abnormality of the encoder. The drive controller controls drive of a motor by switching an energized phase of a motor winding so that a rotation position of the motor becomes a target rotation position according to a target shift range. When the abnormality of the encoder is detected, the driver controller drives the motor by faulty phase identification control to identify a faulty phase that is a phase in which an abnormality of the encoder signal occurs, and a normal phase in which the encoder signal is normal.Type: GrantFiled: April 8, 2021Date of Patent: July 26, 2022Assignees: DENSO CORPORATION, HONDA MOTOR CO., LTD.Inventors: Hiromitsu Nagata, Koji Sakaguchi, Jun Yamada, Masahiko Akiyama, Masashi Misawa, Kenshi Masuo

Publication number: 20210301916Abstract: To provide such a shift apparatus that, at the time of electrically applying a reaction force to a rotation operation of the shift apparatus, a driver is not disabled to perform intended range switching when the application of the reaction force continues. If reaction force application means continues application of a reaction force for a predetermined time or more, reaction force application control means suppresses the application of the reaction force by the reaction force application means. When the reaction force application means has trouble, the driver may want to intentionally switch a range. In this case, the driver's intention to perform an operation is hindered. However, if application of a reaction force is suppressed when the application of the reaction force is continued for a predetermine time, it is possible to avoid the operation by the driver from being hindered.Type: ApplicationFiled: March 23, 2021Publication date: September 30, 2021Inventors: Satoshi KONO, Fumitaka ABE, Masahiko AKIYAMA
