Patent number: 9132903Abstract: Systems and methods are for maneuvering a marine vessel having a plurality of steerable propulsion devices. The plurality of propulsion devices are controlled to achieve a lateral movement by controlling the steering orientation of port and starboard propulsion devices so that forward thrusts provided by the port and starboard propulsion devices intersect at or forwardly of a center of turn of the marine vessel. One of the port and starboard propulsion devices is operated to provide a forward thrust and the other of the port and starboard propulsion devices is operated to provide a reverse thrust so that the lateral movement is achieved and a resultant yaw component is applied on the marine vessel. An intermediate propulsion device is controlled to apply an opposing yaw component on the marine vessel that counteracts the resultant yaw component.Type: GrantFiled: September 26, 2013Date of Patent: September 15, 2015Assignee: Brunswick CorporationInventors: Kenneth G. Gable, William R. Robertson, David M. Van Buren, Glenn E. Anderson, Brad E. Taylor

Patent number: 8694248Abstract: Systems and methods for monitoring the accuracy of a global positioning system (GPS) receiver in a marine vessel utilize a GPS receiver receiving a plurality of satellite signals, calculating a global position of the GPS receiver based on the plurality of signals, and determining a signal to noise ratio (SNR) of each signal in the plurality of signals; and a control circuit having a computer readable medium having executable code, and being connected to the GPS receiver by a communication link. The control circuit calculates an average SNR of the plurality of signals and compares the average SNR to a threshold SNR. In one example the threshold SNR varies depending upon a number of satellites sending the plurality of signals and a speed at which the marine vessel is traveling.Type: GrantFiled: February 8, 2011Date of Patent: April 8, 2014Assignee: Brunswick CorporationInventors: Jason S. Arbuckle, William R. Robertson

Patent number: 8622777Abstract: Systems and methods for maneuvering a marine vessel limit interference by the hull of the vessel with reverse thrust. A marine propulsion device provides at least a reverse thrust with respect to the marine vessel. The propulsion device is vertically pivotable into a trim position wherein the hull does not impede or interfere with the reverse thrust. A control circuit controls the propulsion device to move into the trim position when the reverse thrust of the propulsion device is requested.Type: GrantFiled: June 9, 2011Date of Patent: January 7, 2014Assignee: Brunswick CorporationInventors: Brett J. McNalley, William R. Robertson, Kenneth G. Gable

Patent number: 8478464Abstract: Systems and methods for orienting a marine vessel enhance available thrust in a station keeping mode. A control device having a memory and a programmable circuit is programmed to control operation of a plurality of marine propulsion devices to maintain orientation of a marine vessel in a selected global position. The control device is programmed to calculate a direction of a resultant thrust vector associated with the plurality of marine propulsion devices that is necessary to maintain the vessel in the selected global position. The control device is programmed to control operation of the plurality of marine propulsion devices to change the actual heading of the marine vessel to align the actual heading with the thrust vector.Type: GrantFiled: September 14, 2010Date of Patent: July 2, 2013Assignee: Brunswick CorporationInventors: Jason S.

Patent number: 6679225Abstract: The present invention provides an improvement over conventional engine controls by adjusting engine air/fuel [AF] ratio, as a function of fuel volatility, during engine start and initial operation. It is comprised of three detection tests to determine the volatility of the fuel and provide compensation to the AF ratio in proportion to that volatility during engine crank and initial operation. The method includes compensating for incomplete fuel vaporization as a function of predicted intake valve temperature.Type: GrantFiled: May 16, 2002Date of Patent: January 20, 2004Assignee: Delphi Technologies, Inc.Inventors: William R.

Patent number: 6679108Abstract: A method of synchronizing a crankshaft signal with the stroke cycle of a four-stroke internal combustion engine induces misfiring in a specified engine cylinder, and uses an assumed synchronization to identify the misfiring cylinder. The crankshaft signal is used to identify reference angular positions of the crankshaft intermediate top dead center positions of consecutive cylinders of the engine firing order, and a time difference between successive reference positions is determined. When the assumed synchronization is such that the current rotation of the crankshaft includes the cylinder in which misfiring is induced, the determined time difference is accumulated in a first accumulator; otherwise, the determined time difference is accumulated in a second accumulator. The presence of misfiring causes the two accumulators to diverge in value, and the direction of such divergence is used to determine if the assumed synchronization is correct or incorrect.Type: GrantFiled: May 10, 2002Date of Patent: January 20, 2004Assignee: Delphi Technologies, Inc.Inventors: William R. Robertson, Sergio Eduardo Garcia, Kevin Michael Foley
