Abstract

An electronic Control system for controlling a water vessel in regards to its propulsion, and thrust vectors and its steering.
A helm wheel that has an electronic output that governs the steerage of a water vessel. The control system determines the reactive speed and number of turns needed to accomplish a given turn, this pre-selected speed and distance traveled gives the rudder two different sets of parameters for full rotation of the Helm wheel from full rudder to the Port to full rudder to the starboard The rudder or outboard motor has a sensor that gives the control system information by way of a variable voltage as to its direction and where the rudder is parked.
The steering actuator has a dual motor set up that supply's enough power and torque to control the steering cable and slide bar of three outboard engines.
The Control system's other input is a joystick controller, its output governs the direction of the propulsion of the watercraft in either a forward direction or Aft or reverse direction and in the same movement the throttle will ramp up in rpm's proportionately. The operators movement of the joystick controller determines this control command.
The joystick in its y-axis has built in friction forces that enable it to stay where the operator moves it.

Description

    TECHNICAL FIELD
  • This invention relates to an apparatus for controlling a watercraft utilizing a helm wheel and a feed back sensor for proportional steering control of the vessel and a joystick to control the throttle and shift.
  • BACKGROUND OF THE INVENTION
  • Many aspects of this invention relate in general to the control of throttle and transmission shifting, steering of a water vessel as controlled power movers and more particularly to comprehensively system and methods for providing the operator with linear movement and control of the vessel.
  • Many boat operators have controlled their watercraft by using a devise such as a steering wheel. Likewise many boat operators have controlled their watercraft by means of a control lever to affect the shift and throttle of their engines.
  • These types of control levers and wheels have been used for great many years and are still an effective means for control today.
  • Many powered movers use proportional speed controls in the form of a joystick or an equivalent type of lever or knob that controls an actuator or actuators to do the work of powered moving. Actuators are often Hydraulic and can be that of other form such as pneumatic, Electro-magnetic, or some combination thereof.
  • For those skilled in the art of operating watercraft or sea going vessels it is well known that tight control from lever to the end mover or powered mover is desirable in order to maintain control of the vessel in all types of seas or conditions.
  • Many of the above mentioned types of controls have problems with linkage being slack and a lack precision steering thus causing the vessel operator to steer erratically or over steer.
  • In the field of shifting and throttle control, it has also been noted that by utilizing the aforementioned means to effect shifting and throttle, some problems such as the fluctuation of the joystick or lever used as a control medium exist.
  • This is particularly a problem when the vessel is in high seas or is experiencing the effects of wave action or in high current rivers such as in the Alaskan wilderness where fast and accurate steerage is critical to avoid protruding rocks.
  • The vessel tends to bounce and move about, when this happens the operator transfers this movement to the lever or joystick that he is using to control the vessel thus the results are erratic control of the vessel.
  • In this kind of environment the operator often lacks a place to secure himself while in control. Movers such as hydraulic rams to affect the steering or rudder of a given vessel are very powerful as they produce thousands of pounds of force.
  • Other Movers such as motorized chain or cable actuators or drives however often lack sufficient power needed to move large rudders or multiple outboard engines at the same time.
  • A sizable unmet need has been revealed in relation to optimizing such movements particularly in the interest of enhanced control of steering and shift and throttle on all types of vessels.
  • Related needs include the goal to minimize unnecessary cost and complexity, to enhance the ease of use.
  • It is an object of the present invention to address these and other needs presented by the prior art.
  • Known feedback technology has helped but more has been long needed.
  • Very few applicants have the combination of control devises such as electronic two speed and two turn ratio of helm wheel and a joystick for integrating full control of throttle and shift, thus having a true “Fly by wire” control system.

  • SUMMARY OF THE INVENTION
  • The present invention (known as the Felton Flyer) is just the answer for many unmet needs that have plagued the prior art—aspects of the invention allowing precise yet smooth operation of steering and that of throttle and shift control that is intuitively interpreted and adjusted by the operator.
  • This system presented is a true (Fly by wire) all electronic steering and shift and throttle control system that utilizes the vessel steering cable drive instrument as a means and point of interface for steering control thus eliminating bulky and cumbersome actuator placement at the stem of the vessel.
  • The system is equipped with a powerful two motor synchronized drive actuator that had the ability to drive the motors or rudders of up to three sizable outboards or rudders.
  • It also combines throttle and shift of outboard engines with one deflection either in forward movement or reverse movement of an electronic Joystick that has been fitted with a friction stopping device to ensure the joystick will stay in place where the operator left it.
  • With this configuration of controls, it allows full control of the vessel in harsh conditions and in high speed operating.
  • The two function steering has a quick switch that allows the operator to change the parameters of helm wheel steering in an instant from slow course correction to fast course correction in dangerous conditions such as avoiding partially submerged rocks at hi speeds.
  • This system controls the steering, throttle, shift of any outboard or inboard propulsion systems including any outboard conversion to jet propulsion, its nozzle and deflector thrust assemblies.
  • The following circuit and its description have been developed to facilitate a switchable two stage steering Apparatus utilizing an electronic Helm Wheel.
  • The Steering wheel will operate the same as in a manual steering wheel system in that if the operator turned the wheel to the right or in this application to Starboard the vessels rudder or if an outboard will move the engine towards the right or starboard direction to accomplish the turn.
  • If turning the steering wheel to the Left or to the port direction the rudder or engine will move towards the Left or starboard direction to accomplish the turn. The (Two Stage Circuit) allows the command given by the electric helm wheel to determine its direction and the distance it is to travel.
  • In Stage one primarily used in slow speed or docking applications set the distance and speed the rudder will travel. For an example if the steering wheel is deflected to full right rudder the 1st stage limits the turning radius to an adjustable degree of ¼ turn to (full right rudder) from its center position. If turning the wheel to full left rudder it will do so in ¼ turn from its center position.
  • The second stage if engaged will allow the turning the steering wheel from its center position to full left rudder ¾ turn of the wheel.
  • The full turning radius of stage one could be known as having a turning radius as ½ turn form (lock to lock).
  • The second stage could be known as having a turning radius as one turn and a half (lock to lock)
  • The switching from stage one to stage two and vice versa will be accomplished via a push button affixed to the dash.
  • This system will allow the safe turning of the wheel at high speed so as to not endanger persons or turn over the vessel if deflected at a fast rate.
  • It will also allow the operator to at slow speeds to have a much shorter turning radius when needed such as in a tight slip or while docking the craft.
  • The following description is of the shift and throttle operation commanded by a single axis electronic Joystick controller.
  • The Joysticks Y-axis has a detent that allows it to be unmistakably in it neutral position or it center of throw. Thus the potentiometer will in like manner be in its center or mid value.
  • When the system is on and in its drive mode and the joystick is in its center detent, the system will remain in its neutral transmission mode on the outboard or inboard drives and the throttle or throttles will remain in their respective idle Rpm's.
  • If the joystick is deflected forward fifteen degrees then the forward shift will engage, if the joystick is deflected further for every degree of movement the throttle will increase from its idle Rpm to higher Rpm's as desired.
  • If the joystick is deflected aft or its reverse the same will result with the exception of the reverse gear will now be in engaged. it will be noted that the throttle has an adjustable level limit for the throttle Rpm, this is to ensure that full throttle will not be available in the reverse gears.
  • The control circuit for shift and throttle has a built in adjustable window for shift pause, this is added to ensure that if in the forward gear and the operator pulls back on the joystick too quickly and it goes past its neutral detent or neutral transmission, the reversing gear will not engage until the sufficient time that has been set for pausing has elapsed.
  • This feature will help prevent drive shafts from being snapped and drive gears from becoming stripped.
  • The built in friction force on the joystick keeps the joystick in the position that the operator last left it, this feature enables the operator to concentrate on steering and navigating while underway.
