Benefits of technology

The patent is about a system and method for controlling a position of an implement of a machine relative to a frame of the machine. The system includes an actuating system that moves the implement and a user interface with a control element. The controller receives a target position value for the implement and checks if it fits within a set of whole numbers. The controller then receives an instruction to reset the target position value to a nearby whole number. Based on this instruction, the controller communicates with the actuating system to move the implement to the position corresponding to the reset target position value. This technology allows for precise and intuitive control of the position of the implement.

Problems solved by technology

As such, an operator may not be able to set a desired target position value for the implement.
However, manual operations may be prone to errors and are less efficient.

Embodiment Construction

[0017]Reference will now be made in detail to specific aspects or features, examples of which are illustrated in the accompanying drawings. Wherever possible, corresponding or similar reference numbers will be used throughout the drawings to refer to the same or corresponding parts.

[0018]FIG. 1 illustrates a top view of a machine 100, according to an exemplary embodiment of the current disclosure. In the illustrated embodiment, the machine 100 is a motor grader. The machine 100 may be configured to perform some type of operation associated with an industry such as mining, construction, farming, transportation, or any other industry known in the art. In an example, the machine 100 may be used to alter a surface of a terrain or ground to a final arrangement or contour.

[0019]In the illustrated embodiment, the machine 100 includes a front frame 102 and a rear frame 104. The front frame 102 may be movably coupled with the rear frame 104 such that the front frame 102 may rotate relative t...

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.

Description

TECHNICAL FIELD[0001]The current disclosure relates to an implement of a machine, and more particularly to a system and a method for controlling a position of an implement of the machine.BACKGROUND[0002]In general, machines such as a motor grader may be used to perform earth moving operations such as, levelling a surface of the ground. The machine may typically employ an implement such as a blade to perform one or more earth moving operations. A position of the implement may be controlled either manually or using one or more actuators such as hydraulic cylinders. The actuators may control the position of the implement based on a target position indicated by an operator.[0003]Conventionally, the operator may set a target position for the implement by increasing or decreasing a starting position value. In some cases, the starting position value may change during an operation of the machine or other applications. As such, an operator may not be able to set a desired target position val...
