  • Patent number: 10082788
    Abstract: A system for controlling steering and thrust of a marine vessel's propulsion device includes a joystick assembly providing input signals to a control module. The joystick assembly includes a docking station at the helm; a first electrical connector in the docking station cable-connected to the control module; a detachable base for coupling with the docking station; a handle moveable within the detachable base to generate the input signals; a second, complementary electrical connector in the detachable base; and a wireless transmitter mounted in the detachable base. A wireless receiver communicates with the transmitter and the control module. When the detachable base is coupled to the docking station and the electrical connectors are mated, the cable transmits input signals to the control module. When the detachable base is removed from the docking station and the electrical connectors are disconnected, the wireless transmitter and receiver transmit input signals to the control module.

  • Patent number: 9341501
    Abstract: A system for driving an analog gauge that displays an indication of a condition of a vehicle has a microcontroller that receives signals representing a voltage at a sender terminal of the analog gauge and the condition of the vehicle. The microcontroller determines a desired resistance based on the condition of the vehicle and a current command signal based on the desired resistance and the voltage at the sender terminal. The microcontroller sends the current command signal to a current driver circuit to command a flow of current. The current driver circuit is coupled to the sender terminal and has a virtual resistance simulated by the flow of current through the current driver circuit and the voltage at the sender terminal. The analog gauge is driven according to the virtual resistance of the current driver circuit and displays the indication of the condition of the vehicle.

  • Patent number: 9278746
    Abstract: Systems and methods are for drive-by-wire control of a marine engine. An input device is manually operated to provide operator inputs to an engine control unit (ECU) located with the engine. The ECU has a main processor that controls speed of the engine based upon the inputs. The ECU also has a watchdog processor that receives the inputs and that monitors operations of the main processor based upon the inputs. The operations of the main processor are communicated to the watchdog processor via a communication link. When communication between the main processor and watchdog processor fails, the watchdog processor determines whether the main processor is properly functioning based upon the speed of the engine.

  • Patent number: 9103287
    Abstract: Drive-by-wire control systems and methods for a marine engine utilize an input device that is manually positionable to provide operator inputs to an engine control unit (ECU) located with the marine engine. The ECU has a main processor that receives the inputs and controls speed of the marine engine based upon the inputs and a watchdog processor that receives the inputs and monitors operations of the main processor based upon the inputs. The operations of the main processor are communicated to the watchdog processor via a communication link. The main processor causes the watchdog processor to sample the inputs from the input device at the same time as the main processor via a sampling link that is separate and distinct from the communication link. The main processor periodically compares samples of the inputs that are simultaneously taken by the main processor and watchdog processor and limits the speed of the engine when the samples differ from each other by more than a predetermined amount.

  • Patent number: 9014909
    Abstract: A system and method are for diagnosing a fault state of a shift linkage in a marine propulsion device. A control lever is movable towards at least one of a maximum reverse position and a maximum forward position. A shift linkage couples the control lever to a transmission, wherein movement of the control lever causes movement of the shift linkage that enacts a shift change in the transmission. A shift sensor outputs a position signal representing a current position of the shift linkage. A control circuit diagnoses a fault state of the shift linkage when after the shift change the position signal that is output by the shift sensor is outside of at least one range of position signals that is stored in the control circuit.

  • Patent number: 8224512
    Abstract: A control system is provided which allows the operator of a marine vessel to select a transmission position (e.g. forward, neutral, or reverse) and an engine speed in the event that a throttle lever malfunctions. By providing messages to the operator on an annunciator and receiving selections from the operator on a plurality of push button switches, a microprocessor selects gear positions and engine operating speed in response to commands received from the operator.

  • Patent number: 7156709
    Abstract: The calibration procedure allows an upward maximum limit of tilt to be automatically determined and stored as an operator rotates a marine propulsion device relative to a marine vessel with a particular indication present. That indication can be a grounded circuit point which informs a microprocessor that at calibration procedure is occurring in relation to an upward trim limit. When the ground wire is removed or disconnected from the circuit point, the microprocessor knows that the calibration process is complete. During the rotation of the outboard motor or marine propulsion device in an upward direction, both the angular position of the outboard motor and the direction of change of a signal from a trim sensor are stored.
