Publication number: 20230258474Abstract: A detecting unit generates detection signals corresponding to a plurality of ranges aligned in one direction along a moving direction of a detection body, based on a change in the magnetic field constantly received by a detecting element from the detection body. A signal processing unit acquires a detection signal from the detecting unit, compares the detection signal with a threshold value, and identifies a position of the detection body as a position of any one of a plurality of ranges based on a combination of a magnitude relationship between the detection signal and the threshold value. A detection body has a plurality of region portions corresponding to a plurality of ranges. The plurality of region portions are configured to be connected stepwise in the moving direction of the detection body within a plane of a detection surface facing the detecting unit of the detection body.Type: ApplicationFiled: April 18, 2023Publication date: August 17, 2023Inventors: TETSUYA OHMI, MICHIHIRO MAKITA, MASAHIKO AKIYAMA, MASASHI MISAWA, KENSHI MASUO

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: 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
