System and method for controlling position of machine implement

Abstract

A method of controlling a position of an implement of a machine relative to a frame of the machine is provided. The method includes receiving a target position value for the implement and determining if the target position value falls within a set of whole numbers. The method also includes receiving, via a control element of a user interface, an instruction to reset the target position value to a nearest whole number. The method further includes moving the implement to a position corresponding to the target position value that is reset to the nearest whole number based on the instruction.

What is claimed is: 
     
         1 . A method of controlling a position of an implement of a machine relative to a frame of the machine, the method comprising:
 receiving a target position value for the implement;   determining if the target position value falls within a set of whole numbers;   receiving, via a control element of a user interface, an instruction to reset the target position value to a nearest whole number; and   moving the implement to a position corresponding to the target position value that is reset to the nearest whole number based on the instruction.   
     
     
         2 . The method of  claim 1 , wherein a retention of the control element in a first control position or a second control position for at least a predetermined duration is indicative of the instruction to reset the target position value. 
     
     
         3 . The method of  claim 2 , wherein the target position value is reset to the nearest whole number that is greater than the target position value if the instruction is indicated by retention of the control element in the first control position. 
     
     
         4 . The method of  claim 2 , wherein the target position value is reset to the nearest whole number that is less than the target position value if the instruction is indicated by retention of the control element in the second control position. 
     
     
         5 . The method of  claim 2  further comprising receiving, via the user interface, an input indicative of an offset adjust value. 
     
     
         6 . The method of  claim 5  further comprising receiving, via the user interface, an instruction to modify the target position value based on the offset adjust value, wherein the modification is one of increasing or decreasing the target position value by the offset adjust value. 
     
     
         7 . The method of  claim 6 , wherein a retention of the control element in the first control position or the second control position for less than the predetermined duration is indicative of the instruction to modify the target position value based on the offset adjust value. 
     
     
         8 . The method of  claim 7 , wherein the target position value is increased by the offset adjust value if the instruction is indicated by the retention of the control element in the first control position for less than the predetermined duration; and
 wherein the target position value is decreased by the offset adjust value if the instruction is indicated by the retention of the control element in the second control position for less than the predetermined duration.   
     
     
         9 . The method of  claim 1 , wherein the target position value is indicative of a cross-slope angle of the implement. 
     
     
         10 . A system for controlling a position of an implement of a machine relative to a frame of the machine, the system comprising:
 an actuating system configured to move the implement relative to the frame of the machine;   a user interface comprising a control element; and   a controller communicably coupled to the actuating member and the user interface, the controller configured to:
 receive a target position value for the implement; 
 determine if the target position value falls within a set of whole numbers; 
 receive an instruction, via the control element, to reset the target position value to a nearest whole number; and 
 communicate with the actuating system to move the implement to a position corresponding to the target position value that is reset to the nearest whole number based on the instruction. 
   
     
     
         11 . The system of  claim 10 , wherein a retention of the control element in the first control position or the second control position for at least a predetermined duration is indicative of the instruction to reset the target position value to the nearest whole number. 
     
     
         12 . The system of  claim 11 , wherein the controller is configured to reset the target position value to the nearest whole number that is less than the target position value if the instruction is indicated by retention of the control element in the first control position. 
     
     
         13 . The system of  claim 9 , wherein the controller is configured to reset the target position value to the nearest whole number that is greater than the target position value if the instruction is indicated by retention of the control element in the second control position. 
     
     
         14 . The system of  claim 10 , wherein the controller is further configured to receive, via the user interface, an input indicative of an offset adjust value. 
     
     
         15 . The system of  claim 14 , wherein the controller is further configured to receive, via the user interface, an instruction to modify the target position value based on the offset adjust value, wherein the modification is one of increasing or decreasing the target position value by the offset adjust value. 
     
     
         16 . The system of  claim 10 , wherein the user interface further comprises a display screen communicably coupled to the controller, the display screen configured to display the target position value. 
     
     
         17 . The system of  claim 10 , wherein the control element is one of a switch, a button and a graphical control element on a touch-sensitive screen. 
     
     
         18 . A machine comprising:
 a frame;   an implement operatively coupled to the frame;   an actuating system configured to move the implement relative to the frame of the machine;   a user interface comprising a control element; and   a controller communicably coupled to the actuating member and the user interface, the controller configured to:
 receive a target position value for the implement; 
 determine if the target position value falls within a set of whole numbers; 
 receive an instruction, via the control element, to reset the target position value to a nearest whole number; and 
 communicate with the actuating system to move the implement to a position corresponding to the target position value that is reset to the nearest whole number based on the instruction. 
   
     
     
         19 . The machine of  claim 18 , wherein a retention of the control element in a first control position or a second control position for at least a predetermined duration is indicative of the instruction to reset the target position value to the nearest whole number. 
     
     
         20 . The machine of  claim 18 , wherein the controller is further configured to:
