  • Publication number: 20210300517
    Abstract: A marine vessel control system comprises a propulsion unit and a steering actuator for steering the propulsion unit. There is a shift actuator for shifting gears in the propulsion unit and a throttle actuator for increasing or decreasing throttle to the propulsion unit. There is an input device for providing user inputted steering commands to the steering actuator and for providing user inputted shift and throttle commands to the shift actuator and the throttle actuator. There is a sensor for detecting a global position and a heading direction of the marine vessel. A controller receives position and heading values of the marine vessel from the sensor. The controller compares the received position value to a pre-programmed position value to determine a position error difference. The controller also compares the received heading value to a pre-programmed heading value to determine a heading error difference.

  • Publication number: 20210188411
    Abstract: An actuator for imparting steering movement to a tiller of a propulsion unit of a marine vessel comprises an absolute position sensor operable to sense a steering position and a relative position sensor operable to sense a position of the motor. A steering control unit calibrates the relative position sensor based on a signal of the absolute position sensor. Calibration of the relative position sensor based on a signal of the absolute position sensor initializes an accumulative position which accumulates a relative position as the actuator moves over time.

  • Patent number: 10988224
    Abstract: An electric actuator comprises a housing and an output shaft reciprocatingly received by the housing. There is a screw assembly disposed within the housing and coupled to the output shaft. The screw assembly includes a plurality of annular rollers and a central screw received by the annular rollers. The annular rollers are rotatable about the central screw. There is a motor which includes a stator and a rotor. The rotor has an inner bore which engages the annular rollers. Rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing.

  • Patent number: 10889358
    Abstract: There is provided a mounting assembly for a marine vessel having a pair of stern-mounted propulsion units. The assembly includes a pair of angle-setting members which forwardly angle the propulsion units towards a bow of the marine vessel when each propulsion unit is at the center of its total steering range. Each propulsion unit has a line of action of its propulsion force. The lines of action of the propulsion units intersect each other between a center of rotation of the marine vessel and a stern of the marine vessel when the propulsion units are steered forwardly towards each other.

  • Patent number: 10696368
    Abstract: An inner circumferential surface of a clamp bracket is open at an inner side surface of the clamp bracket. At least a portion of a movable body is surrounded by the inner circumferential surface in a side view. The movable body is movable to a plurality of positions including a position above a swivel bracket and a position inside a space surrounded by the inner circumferential surface of the clamp bracket. A steering shaft rotates around a steering axis along with movement of the movable body.
