System for providing thruster effect on a vessel

Abstract

A remote-control unit for control a marine vessel is provided with a thruster actuator and engine actuators. When the marine vessel lacks a thruster, the thruster actuator, when operated, causes the remote-control unit to transmit engine control signals to each of at least two engines to achieve a virtual thruster effect by the marine vessel.

What is claimed is: 
     
         1 . A remote-control unit for operating a marine vessel, comprising: 
 at least one thruster control that is capable of controlling both a thruster as well as each of the port main engine and the starboard main engine;   a radio transceiver;   wherein the thruster control is configured to cause the remote-control unit to transmit, via the radio transceiver, main engine control signals to jointly operate both the port main engine and the starboard main engine to achieve a virtual thruster effect on the marine vessel, according to a thruster profile that is stored in the remote control unit.    
     
     
         2 . The remote-control unit of  claim 1 , wherein the at least one main engine control is a joystick.  
     
     
         3 . The remote-control unit of  claim 1 , wherein the thruster profile stored in the remote-control unit includes a ramp up time parameter, a direction parameter, an engine speed parameter, and a duration parameter for the port main engine and a ramp up time, a direction, an output level, and a duration for the starboard main engine.  
     
     
         4 . The remote-control unit of  claim 3 , wherein the thruster profile is selected, via an input on the remote control, from among at least two thruster profiles stored in the remote-control unit.  
     
     
         5 . The remote-control unit of  claim 1 , further comprising a WiFi transceiver via which the thruster profile can be edited, and additional thruster profiles can be added to the remote-control unit.  
     
     
         6 . The remote-control unit of  claim 1 , wherein the radio transceiver is configured scroll through a plurality of frequencies when transmitting.  
     
     
         7 . The remote-control unit of  claim 1 , wherein the radio transceiver is configured to transmit across two radio bands.  
     
     
         8 . A remote-control unit for operating a marine vessel, comprising: 
 a radio transceiver; and   at least one thruster control actuator that is configured to, when actuated, cause the remote-control unit to transmit, via the radio transceiver, engine control signals to operate both the port main engine and the starboard main engine to achieve a virtual thruster effect on the marine vessel, wherein the engine control signals are transmitted according to a thruster profile stored on the remote-control unit.    
     
     
         9 . The remote-control unit of  claim 8 , wherein the at least one thruster control actuator is a lever actuator.  
     
     
         10 . The remote-control unit of  claim 8 , wherein the thruster profile is stored in the remote-control unit in a non-volatile memory, and includes a ramp up parameter, a direction parameter, an engine speed parameter, and a duration parameter for each of the port main engine and the starboard main engine.  
     
     
         11 . The remote-control unit of  claim 10 , wherein the virtual thruster profile is selected, via an input on the remote-control unit, from among at least two virtual thruster profiles stored in the remote-control unit.  
     
     
         12 . The remote-control unit of  claim 8 , further comprising a WiFi transceiver via which the thruster profile can be edited, and additional thruster profiles can be added to the remote-control unit. 
     
     
         13 . The remote-control unit of  claim 8 , wherein the radio transceiver is configured scroll through a plurality of frequencies when transmitting.  
     
     
         14 . The remote-control unit of  claim 8 , wherein the radio transceiver is configured to transmit across two radio bands. 
     
     
         15 . The remote-control unit of  claim 8 , wherein the at least one thruster control actuator comprises a bow thruster control actuation and an aft thruster control actuator. 
     
     
         16 . A method for operation of a remote-control unit for a marine vessel, the remote-control unit having a thruster actuator, the method comprising: 
 operating the thruster actuator; and   responsive to operating the thruster actuator, the remote-control unit transmitting, via a radio transceiver, main engine control signals for each of at least two main engines of the marine vessel to cause a virtual thruster effect by the marine vessel, including transmitting the main engine control signals according to a thruster profile stored in the remote-control unit.   
     
     
         17 . The method of  claim 16 , wherein the thruster profile stored in the remote-control unit specifies a ramp up parameter, a direction parameter, an engine speed parameter, and a duration parameter for each of the at least two main engines.  
     
     
         18 . The method of  claim 17 , further comprising selecting the virtual thruster profile, via an input on the remote control, from a plurality of virtual thruster profiles that are stored in the remote-control unit.  
     
     
         19 . The method of  claim 16 , wherein the remote control unit includes at least one main engine actuator, the method further comprising:  
       operating the at least one main engine actuator; and 
       responsive to operating the at least one main engine actuator the remote-control unit transmitting main engine control signals, via the radio transceiver, for at least one of the at least two main engines.
