  • Publication number: 20220147061
    Abstract: A method of controlling tilt-trim position of a trimmable device on a marine vessel includes determining a trim rate based on rotational speed of a propulsion device on the marine vessel, the vessel speed of the marine vessel, the vessel pitch of the marine vessel, and/or the vessel acceleration of the marine vessel. The trim rate specifies a rate of rotation of the trimmable device about a horizontal axis, and the trim rate is determined such that the rate of rotation is minimized at high vessel speeds and high rotational speeds and the rate of rotation is maximized at low vessel speeds and low rotational speeds. A variable speed trim actuator is then controlled to rotate the trimmable device based on the trim rate so as to adjust a trim position of the trimmable device.

  • Patent number: 11254402
    Abstract: A method of controlling propulsion for automated launch control includes receiving a user-selected command associated with wake surfing, accessing a predetermined RPM limit associated with the user-selected command, and automatically increasing rotational speed of a powerhead to accelerate the marine vessel to a vessel speed setpoint such that the rotational speed does not exceed the predetermined RPM limit. Once the marine vessel is traveling at the vessel speed setpoint, a cruising RPM value associated with the vessel speed setpoint is identified. A difference between the predetermined RPM limit and the cruising RPM value is determined, and then the predetermined RPM limit is adjusted to an adapted RPM limit based on the difference. The adapted RPM limit is then stored for use during a subsequent launch.

  • Patent number: 10633072
    Abstract: A method for positioning a marine vessel includes receiving a measured actual position of the vessel and determining a first error between the actual position of the vessel and a desired target position of the vessel. In response to the first error being in a fore/aft direction of the vessel, the method includes commanding a first subset of marine propulsion devices in a plurality of marine propulsion devices to produce thrust to minimize the first error in the fore/aft direction, as appropriate, while a remainder of the marine propulsion devices in the plurality do not produce thrust. The method thereafter includes commanding the first subset of marine propulsion devices to cease producing thrust. The method may also include selecting whether to actuate all marine propulsion devices in the plurality of marine propulsion devices or a first subset thereof based on a magnitude and a direction of the first error.

  • Patent number: 10518856
    Abstract: A trim control system includes a memory storing a plurality of trim profiles, each trim profile defining a unique relationship between a plurality of vessel speeds and respective propulsion device trim angles. The unique relationship is: (a) a calibrated relationship developed by determining optimal trim angles for a particular propulsion device powering a particular marine vessel at a number of tested vessel speeds and a number of different conditions; or (b) developed by modifying a nominal relationship between a number of vessel speeds and a number of corresponding trim angles. An input device allows a user to select one of the trim profiles from the memory so as to specify an aggressiveness of trim angle relative to vessel speed. A controller determines a setpoint trim angle corresponding to measured vessel speed according to the selected trim profile. The control system positions the propulsion device at the setpoint trim angle.

  • Patent number: 10351221
    Abstract: A method for controlling a trim position of a marine propulsion device includes receiving operator demands corresponding to propulsion system operating speeds and determining a rate of change of demand versus time between an initial and a subsequent operator demand. When the rate of change of demand exceeds a predetermined rate, the control module uses successively measured operating speeds of the propulsion system and an offset trim profile to determine setpoint trim positions for the propulsion device. As the propulsion system's measured operating speed increases from an initial to a subsequent operating speed, the control module controls a trim actuator to rotate the propulsion device to the setpoint trim positions. An operating speed at which the propulsion device begins trimming up is less according to the offset trim profile than according to a base trim profile, which is utilized when the rate of change does not exceed the predetermined rate.

  • Patent number: 10322786
    Abstract: A method for controlling a marine engine's operating mode includes operating the engine in an initial operating mode according to an initial set of mapped parameter values configured to achieve an initial fuel/air equivalence ratio of an air-fuel mixture for combustion. If measured operating conditions of the engine meet lean-burn mode enablement criteria, the engine is operated in lean-burn mode according to a lean-burn set of mapped parameter values configured to achieve a lean-burn fuel/air equivalence ratio that is less than the initial fuel/air equivalence ratio. If the measured engine operating conditions no longer meet the lean-burn mode enablement criteria, the engine is operated in the initial operating mode. Transitions between the lean-burn mode and the initial operating mode are monitored. If the transitions indicate that the engine's operating mode is unstable, the engine is prevented from operating in the lean-burn mode until after a reset condition has been met.
