For example, auto-dock controller 330 may include a threshold that a pitch and/or roll of pontoon boat 100 must be less than, such as 10 degrees, 5 degrees, or 3 degrees, for auto-dock controller 330 to continue. In embodiments, sensors 306 may further include a wind sensor (not shown) and auto-dock controller 330 may include a threshold that wind speed must be less than, such as 20 miles per hour, for auto-dock controller 330 to continue.

Sensors 306 may include one or more stereo cameras 412. Stereo cameras 412 provide a three-dimensional geometry of the surroundings of pontoon boat 100 in the range of 10-15 meters from the stereo cameras 412. An advantage, among others, of stereo cameras 412 is that they are able to provide visible light video to operator interface 374 of remote operator device 300 for display.

Referring to FIG. 10, a representation of a coverage area of the four stereo cameras 412 is illustrated. Additional stereo cameras or other imaging sensors may be positioned at various locations on pontoon boat 100. In embodiments, at least some stereo cameras are oriented such that a line connecting the respective cameras of a stereo camera is angled relative to horizontal, such as vertical, to enhance the ability of the system to recognize horizontal features (dock, boats, and other objects). In embodiments, at least some stereo cameras are oriented such that a lone connecting the respective cameras of a stereo camera is horizontal to enhance the ability of the system to recognize vertical features such as on boat lifts or posts. Exemplary locations include on or affixed to a top rail or portion of barrier 108, on or affixed to deck 104, on or affixed to gate 110, on or affixed to canopy or roof structure, or other suitable locations. In embodiments, pontoon boat 100 includes a bow camera 412 and a stern camera 412, each centered on or positioned near longitudinal centerline 140 of pontoon boat 100. In embodiments, stereo cameras are moveable between a stored position and a use position when the auto-dock feature is in use. As an example, the stereo cameras 412 may be supported by deck 104 on telescoping mounts. The stereo cameras 412 are positioned proximate the deck 104 when the auto-dock feature is not in use (“stored position”) and raised relative to the stored position, either automatically or manually, to a raised use position when the auto-dock feature is in use.

Referring to FIG. 11, an exemplary processing sequence of auto-dock controller 330 of pontoon boat 100 is illustrated. Auto-dock controller 330 includes a localization component 430, a perception component 432, a mission planner component 434, and a navigation component 436. Localization component 430 receives the inputs from sensors 306, such as from GPS/magnetometer 400, IMU system 410, stereo cameras 412, LIDAR system 402, and radar system 414. Based on those inputs, localization component 430 locates pontoon boat 100 and, in embodiments, corresponding objects in the environment surrounding pontoon boat 100. Obstacles, reference points, goal points, other water vessels, people, docks, buoys, and/or reference objects may be sensed by one or more sensing systems including visual sensors (e.g. cameras), range sensors (e.g. LIDAR, radar, sonar), stereo sensing, projected light visual sensing, beacon detection, sonar, and proximity sensors. In embodiments, localization component 430 includes a sensor fusion algorithm to estimate a three-dimensional pose of pontoon boat 100. The pose of pontoon boat 100 may be determined by one or more of GPS information, IMU information, visual odometry, visual SLAM, visual feature matching, point cloud matching, triangulation with one or more beacons in the environment, INS, and stereo data matching. Based on this information, the local pose estimate of pontoon boat 100 and potential location of obstacles, are provided to perception component 432.

Perception component 432 detects, such as with stereo cameras 412 and LIDAR system 402, and tracks the objects in the environment surrounding pontoon boat 100 (e.g. other boats or swimmers) and a target docking location, such as location 440 (see FIG. 10), with respect to pontoon boat 100. In embodiments, perception component 432 determines a representation of the environmental around boat 100 and semantically labels objects in the representation of the environment like boats and docks based comparisons to learned objects accessible by the logic that have been classified as docks or boats. Based on the location of the objects an audible warning may be sounded with a speaker or horn. Perception component 432 outputs to mission planner component 434 the locations of the obstacles in the surrounding environment and the target docking location with respect to the frame of reference of pontoon boat 100. The target docking location may correspond to a location proximate a dock, a location proximate a boat slip, a location of a boat lift, a portion of a sandbar/beach, or other suitable locations. In embodiments, a good docking location is determined by based on the dimensions of boat 100 to ensure there is ample room to maneuver and dock boat 100, a planar nature of the environmental object identified as a dock, and an openness of the dock area to allow for docking and disembarking from boat 100.

Mission planner component 434 identifies a navigation plan to navigate pontoon boat 100 to the target docking location 440 while avoiding the objects in the environment surrounding pontoon boat 100. In embodiments, mission planner component 434 uses a dynamic graph based on the information from perception component 432 to estimate path and trajectory for pontoon boat 100. Mission planner component 434 outputs navigation waypoints to navigation component 436.

Navigation component 436 controls one or more of outboard prime mover system 308, thruster system 200, and steering system 312 to navigate pontoon boat 100 to location 440. In embodiments, navigation component 436 determines the control of outboard prime mover system 308, thruster system 200, and steering system 312 to navigate pontoon boat 100 along the navigation waypoints output by mission planner component 434. In one example, navigation component 436 utilizes a PID algorithm to provide a smooth movement along the navigation waypoints. In other examples, navigation component 436 utilizes one or more of predictive control, PI, PID, PD, sliding mode control, and/or other suitable control schemes. In embodiments, navigation component 436 adjusts the control of outboard prime mover system 308, thruster system 200, and steering system 312 based on at least one of a sensed weight distribution on boat 100, a wind characteristic, and a current of water 12.

Referring to FIG. 19, an exemplary processing sequence 600 for navigation component 436, in embodiments, is shown. With the GPS sensor 400 a measurement is received of a location of boat 100. Further, the current commanded control velocity of boat 100 is received, as represented by block 602. Based on the position and heading of boat 100 and commanded velocity, a deviation in the motion of boat 100 from an expected location of the boat is determined, as represented by block 604. Additionally, inputs are received from a wind speed and direction sensor 340 and a water current sensor 342. Based on the calculated deviation in boat position 604, the output of wind sensor 340, and the output of water current sensor 342, an estimate of additional disturbances on boat 100 due to environmental conditions may be determined, as represented by block 606.

Referring to FIG. 20, an exemplary processing sequence 670 for navigation component 436, in embodiments, is shown. Navigation component 436 receives an input from IMU 410 which provides an indication of how boat 100 is sitting in water 12. If the weight supported by boat 100 is not evenly distributed, boat 100 will not sit level in water 12. Further, changes in the weight distribution of the boat 100, such as due to people moving around, results in a change in the center of mass and moment of inertia of boat 100, as represented by blocks 672 and 674. This change perturbs the angle of boat 100 in water 12, as represented by block 676, which is measured by IMU 410, as represented by block 678. These changes in weight distribution changes the response of boat 100 as it moves through water 12. Navigation component 436 includes this change in weight distribution into account when determining the next control velocity command for outboard prime mover system 308, thruster system 200, and steering system 312 to move to a target position.

Referring to FIG. 12, a timing diagram 450 of an exemplary operation of auto-dock controller 330 is shown. Initially, the auto-dock processing sequence is started, as represented by block 452. Leading up to the start of the auto-dock processing sequence, an operator of pontoon boat 100 moves pontoon boat 100 within range of a dock or other mooring location, as represented by block 454, and auto-dock controller 330 localizes the position of pontoon boat 100, as represented by block 456, with localization component 430. Once the auto-dock processing sequence is begun, auto-dock controller 330 senses the environment around pontoon boat 100, as represented by block 458, and rectifies and processes sensor data from sensors 306, as represented by block 460, with perception component 432. In embodiments, the auto-dock processing sequence is begun in response to the selection of an input 462 provided on an input screen 464 on operator interface 374 (see FIG. 15).

Input screen 464 illustrates a target docking location 466 determined by auto-dock controller 330 based on the size of pontoon boat 100 and a corresponding sized area proximate the dock. The operator confirms the displayed target docking location by selecting it, as represented by block 470 in FIG. 12 and illustrated in FIG. 16.

Once the docking location 466 is selected, auto-dock controller 330 begins determining the path and trajectory of pontoon boat 100, as represented by blocks 472 and 474, and controlling one or more of outboard prime mover system 308, thruster system 200, and steering system 312 to move pontoon boat 100 to the docking location, as represented by block 476. The path and trajectory of pontoon boat 100 is updated multiple times during the movement of pontoon boat 100 to the docking location 466 as represented by loop 478. In embodiments, block 472 is a global path and trajectory to move pontoon boat 100 from its current position to the docking location and block 474 is a local path and trajectory to move pontoon boat 100 to the next waypoint along the global path and trajectory. In embodiments, the auto-dock controller 330 may receive an input from a sensor monitoring an area in front of a control panel of boat 100. In embodiments, the auto-dock controller 330 may fail to initiate or stop an ongoing auto-dock procedure if an operator is not sensed being in front of the control panel of the boat 100. In embodiments, a switch is provided as part of the control panel or at another location on pontoon boat 100 and the auto-dock controller 330 may fail to initiate or stop an ongoing auto-dock procedure based on the status of the switch. In one embodiment, the switch is a deadman switch which requires the user to apply active force to keep the switch closed. If the user stops applying force, the switch opens and the auto-dock procedure is stopped. Further, an audio, visual, and/or tactile feedback can be provided. In one embodiment, the switch is a liveman switch which requires a user to apply active force to keep the switch closed, but if force over a threshold amount is applied, the switch opens. Similar to the deadman switch, if the user does not apply active force, the switch opens. If the user stops applying force or applies excessive force, the auto-dock procedure is stopped.

Referring to FIG. 17, during the movement of pontoon boat 100 to the docking location 466, remote operator device 300 presents feedback to the operator of the position of pontoon boat 100. Further, screen 464 presented on operator interface 374 includes a cancel docking input region which if selected would cancel the auto-docking process. As shown in FIG. 18, once pontoon boat 100 is in the docking position, screen 464 provides a message to the operator that docking is complete and pontoon boat 100 should be moored to the dock or other mooring location. In embodiments, one or both of remote operator device 300 and operator interface 374 provide one or more of audio, visual, and tactile feedback to the user of when pontoon boat 100 is in the docking position, when an obstacle is near, or other specified scenarios.

Returning to FIG. 12, block 480 represents when pontoon boat 100 is positioned in the confirmed target docking location 466. Once in the confirmed target docking location 466, auto-dock controller 330 operates to maintain pontoon boat 100 in a mooring configuration at the docking location 466 until the auto-docking process is ended, as represented by blocks 482 and 484. In the mooring configuration, the pontoon boat 100 remains essentially stationary to allow an operator to tie up, or moor the vessel to the docking structure. In the case of a dock or slip the system may maintain a position of the boat 100 relative to the dock or slip sides. In the case of a boat lift, the system may maintain a center of mass of boat 100 between the lifts. During this process, remote operator device 300 is monitoring the weight of pontoon boat 100 and the current of the water pontoon boat 100 is positioned in, as represented by block 486. This data is processed to update requirements of thruster system 200 to maintain the position of pontoon boat 100 relative to the dock as represented by block 488. This process is repeated until the auto-dock process ends, as represented by loop 490. In embodiments, the mooring configuration process ends automatically after a certain amount of time has passed, or it may be controlled via an operator device 300 input, by the operator, once the pontoon boat 100 has been successfully moored.

It is also contemplated that the logic of the mooring configuration process could be utilized outside of a docking process, in which an operator could configure a pontoon boat 100 to simply stay in a stationary position for a period of time in open water to, for example, allow another aquatic vessel to tie up to it, or allow a swimmer to board the pontoon boat
