  • Ship maneuvering system and ship maneuvering method
    Patent number: 11485466
    Abstract: A ship maneuvering system includes a propulsion unit to steer a ship body, a trim adjuster disposed on the ship body, and a controller. The controller is configured or programmed to correct a change in the traveling state of the ship body due to operation of the trim adjuster.
    Type: Grant
    Filed: June 5, 2020
    Date of Patent: November 1, 2022

  • Ship maneuvering system and ship maneuvering method
    Patent number: 11472530
    Abstract: A ship maneuvering system includes a propulsion unit to steer the ship body, a trim adjuster on the ship body, a detector to detect a traveling state of the ship, and a controller. The controller operates the trim adjuster in a state in which the steering angle of the propulsion unit is set to a first steering angle. The controller sets the steering angle of the propulsion unit to a second steering angle different from the first steering angle to correct a change of the traveling state of the ship due to an operation of the trim adjuster.

  • Outboard motor
    Patent number: 10336426
    Abstract: A trim-tilt device includes a first electric motor electrically connected to a power source and tilts an outboard motor body in an up-and-down direction. A steering device includes a second electric motor electrically connected to the power source. The steering device turns the outboard motor body in a right-and-left direction. A fuel pump is electrically connected to the power source, and supplies fuel to an engine. A controller limits an inrush current into the first electric motor using a PWM control for a predetermined period of time from a starting time point of an input current into the first electric motor.
