Marine propulsion systems and methods
Marine vessel propulsion systems and methods for controlling speed and direction of marine vessel propulsion systems. A processing device can receive, from a user device, a signal indicative of a desired direction and speed input to the user device; store the desired direction and speed signal in the memory; generate control signals indicative of a power input, wherein each of the control signals is associated with a particular motor of the marine vessel propulsion system; and transmit each of the control signals to a corresponding one of the motors to move the marine vessel in a desired direction and at a desired speed.
1. A marine vessel propulsion system, comprising:
a plurality of motors comprising a left motor and right motor;
a memory;
a processing device operatively coupled to the memory, wherein the processing device is to:
receive, from a user device, a signal indicative of a desired direction and speed input to the user device;
store the desired direction and speed signal in the memory;
generate a plurality of control signals indicative of a power input, wherein each of the plurality of control signals is associated with a particular one of the plurality of motors of the marine vessel propulsion system; and
transmit each of the control signals to a corresponding one of the motors to move the marine vessel in a desired direction and at a desired speed, wherein:
the user device comprises a joystick,
the desired direction and speed are based on a position of the joystick,
the position of the joystick is indicated by a position of a handle of the joystick as it relates to a coordinate chart, and
each of the plurality of control signals is generated based on an x,y coordinate of the handle, wherein the plurality of control signals comprises a power level for the right motor (R) being based on the formula R=(y−x)*k and a power level for the left motor (L) being based on the formula L=(y+x)*k, where k=1.4.
2. The system of claim 1 , wherein each of the control signals inputs a speed and direction to the corresponding one of the motors.
3. The system of claim 2 , wherein each of the plurality of motors is a marine jet and the direction of the motor is forward or reverse.
4. The system of claim 1 , wherein the x,y coordinate of the handle is indicative of an overall desired direction of the marine vessel propulsion system.
5. A method of controlling speed and direction of a marine vessel, comprising:
receiving, from a user device, a signal indicative of a desired direction and speed input to the user device;
storing the desired direction and speed signal in the memory;
generating a plurality of control signals indicative of a power input, wherein each of the plurality of control signals is associated with a particular one of a plurality of motors of the marine vessel, wherein the plurality of motors comprises a left motor and right motor; and
transmitting each of the control signals to a corresponding one of the motors to move the marine vessel in a desired direction and at a desired speed, wherein:
the user device comprises a joystick,
the desired direction and speed are based on a position of the joystick,
the position of the joystick is indicated by a position of a handle of the joystick as it relates to a coordinate chart, and
each of the plurality of control signals is generated based on an x,y coordinate of the handle, wherein the plurality of control signals comprises a power level for the right motor (R) being based on the formula R=(y−x)*k and a power level for the left motor (L) being based on the formula L=(y+x)*k, where k=1.4.
