Abstract

Systems and methods for operating a grading machine. The method includes (i) receiving information regarding material on a surface, and the grading machine is configured to travel on the surface and move the material on the surface; (ii) determining a set of parameters for operating the grading machine, and the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine; and (iii) positioning a snow wing and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard.

First claim

The invention claimed is:

1 . A method for operating a grading machine, comprising:
receiving information regarding material on a surface, wherein the grading machine is configured to travel on the surface and move the material on the surface; determining a set of parameters for operating the grading machine, wherein the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine, wherein the articulation angle is formed by a center axis of the grading machine and a shifted axis of the grading machine; and positioning a snow wing from a first position to a second position and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard, wherein the second position is determined at least based on the articulation angle, wherein the snow wing is dynamically positioned relative to the moldboard based on a result of continuous monitoring of the articulation angle during an operation of the snow wing.

2 . The method of claim 1 , wherein the predetermined spatial relationship includes that the snow wing is in alignment with the moldboard.

3 . The method of claim 1 , wherein the predetermined spatial relationship includes that the snow wing forms an obtuse angle with the moldboard.

4 . The method of claim 1 , further comprising regulating, by a controller of the grading machine, an orientation of the moldboard based on the set of parameters.

5 . The method of claim 1 , further comprising regulating, by a controller of the grading machine, an orientation of the snow wing based on the set of parameters.

6 . The method of claim 1 , wherein the set of parameters is determined based on a predetermined operational configuration chosen by an operator.

7 . The method of claim 6 , wherein the predetermined operational configuration includes:
aligning the snow wing at the first position with the moldboard at a third position corresponding to the first position; and aligning the snow wing at the second position with the moldboard at a fourth position corresponding to the second position.

8 . The method of claim 7 , wherein the predetermined operational configuration includes laterally shifting a front wheel of the grading machine so as to form the articulation angle of the grading machine.

9 . The method of claim 7 , wherein the predetermined operational configuration includes leaning a front wheel of the grading machine.

10 . The method of claim 7 , wherein the predetermined operational configuration includes positioning a front blade of the grading machine so as to align with the snow wing and the moldboard.

11 . The method of claim 6 , wherein the predetermined operational configuration includes positioning a v-shaped front blade of the grading machine such that a first portion of the material is directed to the snow wing and a second portion of the material is directed to the moldboard.

12 . The method of claim 11 , wherein the predetermined operational configuration includes positioning the moldboard such that the second portion of the material is further directed to the snow wing.

13 . The method of claim 6 , wherein the predetermined operational configuration includes positioning the snow wing parallel to the surface.

14 . The method of claim 6 , wherein the predetermined operational configuration includes positioning the snow wing to form a tilt angle relative to the surface.

15 . A grading machine comprising:
a processor; a memory communicably coupled to the one processor, the memory comprising computer executable instructions, when executed by the processor, to:
receive information regarding material on a surface, wherein the grading machine is configured to travel on the surface and move the material on the surface;
determine a set of parameters for operating the grading machine, wherein the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine, wherein the articulation angle is formed by a center axis of the grading machine and a shifted axis of the grading machine;
position a snow wing from a first position to a second position and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard, wherein the second position is determined at least based on the articulation angle, wherein the snow wing is dynamically positioned relative to the moldboard based on a result of continuous monitoring of the articulation angle during an operation of the snow wing; and
operate the grading machine based on the set of parameters.

16 . The grading machine of claim 15 , wherein the set of parameters is determined based on a predetermined operational configuration chosen by an operator, and wherein the predetermined spatial relationship includes that the snow wing is in alignment with the moldboard according to the predetermined operational configuration.

17 . The grading machine of claim 16 , wherein the computer executable instructions, when executed by the processor, are to regulate an orientation of the moldboard based on the set of parameters.

18 . The grading machine of claim 16 , wherein the computer executable instructions, when executed by the processor, are to regulate an orientation of the snow wing based on the set of parameters.

19 . A method for operating a grading machine, comprising:
receiving information regarding material on a surface, wherein the grading machine is configured to travel on the surface and move the material on the surface; determining a set of parameters for operating the grading machine, wherein the set of parameters include an articulation angle of the grading machine, a moldboard angle of a moldboard of the grading machine, and a wheel lean angle formed between a wheel of the grading machine and the surface, wherein the articulation angle is formed by a center axis of the grading machine and a shifted axis of the grading machine; positioning a snow wing from a first position to a second position and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard, wherein the second position is determined at least based on the articulation angle, wherein the snow wing is dynamically positioned relative to the moldboard based on a result of continuous monitoring of the articulation angle during an operation of the snow wing; and operating the grading machine based on the set of parameters.
