Patent number: 12366292Abstract: A shift mechanism of an outboard motor has an electric actuator having a movable rod, and a guide structure for guiding a linear motion of a sliding body connected to the movable rod. In addition, the shift mechanism includes a link rod connected to the sliding body and bent to extend in a direction different from the direction of the linear motion of the sliding body. Furthermore, the shift mechanism includes a shift shaft part which is connected to the link rod, performs a rotational motion on the basis of a displacement of the link rod, and switches a range of a transmission mechanism provided below on the basis of the rotational motion.Type: GrantFiled: June 7, 2019Date of Patent: July 22, 2025Assignee: HONDA MOTOR CO., LTD.Inventors: Makoto Yazaki, Toru Kimura, Naoki Aikawa, Tsuyoshi Harada, Yasukata Kohashi, Hikaru Ikeda

Patent number: 12139240Abstract: An outboard motor that has an actuator and a gear change mechanism. The outboard motor also comprises an operation position sensor that detects the operation position of an operation part, a shift position detection unit that detects the actual shift position of the gear shift mechanism, an actuator detection unit that detects the state of the actuator, and a control device. The control device performs failure determination or drive control of the actuator on the basis of at least two pieces of the detected information.Type: GrantFiled: June 7, 2019Date of Patent: November 12, 2024Assignee: HONDA MOTOR CO., LTD.Inventors: Takamasa Takeshige, Naoki Aikawa

Publication number: 20240166323Abstract: Trim angle control apparatus configured to control a trim angle of an outboard motor including a prime mover, including: a detector configured to detect a rotational speed of the prime mover; an actuator configured to adjust the trim angle of the outboard motor; an operation member configured to be operated by a ship operator to input a change command for changing the trim angle; and an electronic control unit including a processor and memory. The memory stores a target value of the trim angle for each rotational speed range of the prime mover in advance. The processor is configured to perform: setting a target value of the trim angle based on the rotational speed; and controlling the actuator so that the trim angle becomes the target value. The setting includes changing the target value in accordance with the change command when the change command is input through the operation member.Type: ApplicationFiled: March 8, 2021Publication date: May 23, 2024Inventors: Akira Kato, Hiroshi Yamamoto, Naoki Aikawa, Kazumi Miyashita, Akifumi Fujima, Yoshiyuki Misumi, Tokio Unno

Patent number: 11738843Abstract: A shift device for an outboard motor includes a forward gear and a reverse gear; a clutch gear; a shift actuator configured to move between a neutral reference position where the clutch gear is disengaged from the forward gear and the reverse gear and an engagement reference position where the clutch gear is engaged with the forward gear or the reverse gear; and a control device configured to control a movement of the shift actuator. The control device is configured to set an intermediate target position, and to set a speed at which the shift actuator moves from the intermediate target position to the engagement reference position slower than a speed at which the shift actuator moves from the neutral reference position to the intermediate target position.Type: GrantFiled: March 3, 2021Date of Patent: August 29, 2023Assignee: HONDA MOTOR CO., LTD.Inventors: Takamasa Takeshige, Naoki Aikawa, Tomohiro Miyauchi
