  • Patent number: 10845811
    Abstract: A method for maintaining a marine vessel propelled by a marine propulsion device in a selected position includes determining a current global position of the marine vessel and receiving a signal command to maintain the current global position. The current global position is stored as a target global position in response to receiving the signal command. A subsequent global position of the marine vessel is determined and a position error difference between the subsequent global position and the target global position is determined. The method includes determining marine vessel movements required to minimize the position error difference, and causing the marine propulsion device to produce a thrust having a magnitude, a direction, and an angle calculated to result in achievement of the required marine vessel movements. At least one of timing and frequency of discontinuity of thrust production is controlled while the position error difference is minimized.

  • Patent number: 10845812
    Abstract: A system controls movement of a marine vessel near an object. The system includes a control module in signal communication with a marine propulsion system, a manually operable input device providing a signal representing a requested translation of the marine vessel, and a sensor providing a first distance between the vessel and a first point on the object and a second distance between the vessel and a second point on the object. The control module determines an actual angle between the vessel and the object based on the first distance and the second distance. In response to the signal representing the requested translation, the control module stores the actual angle between the vessel and the object as an initial angle and controls the marine propulsion system to produce thrust that will carry out the requested translation and that will maintain the initial angle.

  • Patent number: 10797907
    Abstract: A controller associated with a propulsion device in a marine propulsion system is configured to send and receive controller area network (CAN) messages on a CAN bus and has computer-executable instructions stored thereon executed by a processor of the controller to perform a method. The method includes receiving a configuration instruction CAN message containing a new configuration value, determining that the configuration instruction CAN message is directed to itself, and then receiving a reboot CAN message. Upon determining that the reboot CAN messages directed to itself, the controller writes the new configuration value to memory and then controls a power relay to power off the controller, ignoring a key switch value associated with the propulsion device being on. The controller then responds to the key switch value to power the controller back on, and then loads the new configuration value into the working memory of the controller.

  • Patent number: 10787236
    Abstract: A tiller system for steering an outboard motor. The tiller system includes a tiller arm that is rotatably coupled to the outboard motor. The tiller arm is rotatable from a down position to an up position through a plurality of lock positions therebetween. A tilt lock system is coupled between the tiller arm and the outboard motor and is configured to be activated and deactivated. When activated, the tilt lock system prevents the tiller arm from rotating downwardly through each of the plurality of lock positions. The tiller arm is further rotatable into an unlock position, whereby rotating the tiller arm into the unlock position automatically deactivates the tilt lock system such that the tiller arm is freely rotatable downwardly through the plurality of lock positions.
