Boat steering and propulsion system
View Patent ↗Techniques are disclosed to enable a system for controlling the propulsion and steering of a boat by a boat operator. The boat has at least one propulsion and steering motor assembly connected to the boat with a propeller, and a propulsion motor. It also has left and right pivoting pedals to provide a signal that controls the angle of the propeller so that if the left pedal is pivoted in a first pivot direction by a first percentage and the right pedal is pivoted in a second pivot direction by a second percentage, the boat executes a turn, moves forward, or moves in reverse.
1. A system for controlling the propulsion and steering of a boat by a boat operator having left and right feet, the system comprising:
a propulsion and steering motor assembly connected to the boat, the motor assembly having a single motor;
a left foot-actuated steering control in communication with the left foot of the boat operator and having a left pivot, the left foot-actuated steering control pivoting in a first and second pivot direction to provide a left-foot control signal;
a right foot-actuated steering control in communication with the right foot of the boat operator and having a right pivot, the right foot-actuated steering control pivoting in the first and second pivot direction to provide a right-foot control signal, and
a processor in communication with the left and right foot-actuated steering controls, the processor configured to—
receive the left-foot control signal from the left foot-actuated steering control,
receive the right-foot control signal from the right foot-actuated steering control,
utilize the left-foot control signal and the right-foot control signal to calculate a control command for the single motor, the control command corresponding to a direction and a speed for the single motor, and
provide the control signal to the single motor;
wherein corresponding left and right foot signal control combinations enable the boat operator to control the boat by pivoting the left foot in a first pivot direction by a left pivot percentage and pivoting the right foot in a second pivot direction by a right pivot percentage.
2. The system of claim 1 , wherein the left pivot percentage is 100% forward, the right pivot percentage is 100% forward, and the boat is propelled straight-ahead at full throttle.
3. The system of claim 1 , wherein the left pivot percentage is 100% backwards, the right pivot percentage is 100% backwards, and the boat is propelled rearwards at full throttle.
4. The system of claim 1 , wherein a combination of the left and right pivot percentages causes the boat to turn in a turning direction.
5. The system of claim 4 , wherein the first and second pivot directions are forward and aft respectively.
6. The system of claim 5 , wherein the left pivot percentage is 100% forward, the right pivot percentage is 75% forward, the turn is at a first rate, and the turning direction is right.
7. The system of claim 5 , wherein the left pivot percentage is 75% forward, the right pivot percentage is 0%, the turn is at a second rate, greater than the first rate, and the turning direction is right.
8. The system of claim 1 , wherein the left pivot percentage is forward 50%, the right pivot percentage is backward 50%, the turn is a pirouette, and the turning direction is right.
9. The system of claim 1 , wherein the left foot-actuated steering control includes a first foot pedal and the right foot-actuated steering control includes a second foot pedal.
10. A system for controlling the propulsion and steering of a boat by a boat operator having left and right feet, the system comprising:
a propulsion and steering motor assembly connected to the boat, the motor assembly having a single motor;
a left foot-actuated foot pedal in communication with the left foot of the boat operator and having a left pivot, the left foot-actuated foot pedal pivoting in a first and second pivot direction to provide a left-foot control signal;
a right foot-actuated foot pedal in communication with the right foot of the boat operator and having a right pivot, the right foot-actuated foot pedal pivoting in the first and second pivot direction to provide a right-foot control signal, and
a processor in communication with the left and right foot-actuated foot pedals, the processor configured to—
receive the left-foot control signal from the left foot-actuated foot pedal,
receive the right-foot control signal from the right foot-actuated foot pedal,
utilize the left-foot control signal and the right-foot control signal to calculate a control command for the single motor, the control command corresponding to a direction and a speed for the single motor, and
provide the control signal to the single motor;
wherein corresponding left and right foot signal control combinations enable the boat operator to control the boat by pivoting the left foot in a first pivot direction by a left pivot percentage and pivoting the right foot in a second pivot direction by a right pivot percentage.
11. The system of claim 10 , wherein the left pivot percentage is 100% forward, the right pivot percentage is 100% forward, and the boat is propelled straight-ahead at full throttle.
12. The system of claim 10 , wherein the left pivot percentage is 100% backwards, the right pivot percentage is 100% backwards, and the boat is propelled rearwards at full throttle.
13. The system of claim 10 , wherein a combination of the left and right pivot percentages causes the boat to turn in a turning direction.
14. The system of claim 13 , wherein the first and second pivot directions are forward and aft respectively.
15. The system of claim 14 , wherein the left pivot percentage is 100% forward, the right pivot percentage is 75% forward, the turn is at a first rate, and the turning direction is right.
16. The system of claim 10 , wherein the processor is integrated with the motor.
