Abstract

A system for controlling compaction operations may receive, from one or more sensors associated with a machine performing compaction operations on earthen materials, sensor data indicating a compaction level. The system may determine, during the compaction operations, a compaction level of the earthen materials based on the received sensor data. Further, the system may receive, via an input device on the machine, a first user input indicating an acceptable compaction range. The system may display, via a gauge on a display screen, the determined compaction level and the acceptable compaction range. Further, the system may receive a second user input associated with at least one operating parameter of the machine in response to the determined compaction level being outside the acceptable compaction range. The system may adjust the at least one operating parameter based on the received second user input.

Description

TECHNICAL FIELD The present disclosure relates generally to a work vehicle display, and more particularly, to a work vehicle display with compaction monitoring. BACKGROUND The compaction of asphalt, dirt, sand, rock, and other earthen material is an important step in the construction of road beds, pavements, foundations, dams, runways, landfill liners, etc. Compaction can improve the load bearing capacity of earthen materials, their strength, and their resistance to failure. Depending on the type of compaction material used and the construction requirements, different compaction levels may be desired. As a machine compacts the material, a level of compaction will approach the desired compaction level. A display interface may help an operator of the machine monitor the level of compaction and make determinations on next steps in the compaction process. U.S. Patent Application Publication US 2023/0287638 A1 (“the '638 publication”) published Sep. 14, 2023 and discloses a module configured to receive the compaction value and display and/or indicate the compaction value to a machine operator and/or a site manager. The module can activate an indicator (e.g., a green light) in the cab of the compactor to indicate that the current location is sufficiently compacted. In addition to the displayed compaction value, it may be helpful to provide additional information to the machine operator during the compaction operations. The compaction monitoring and display of the present disclosure solves one or more problems of the prior art.
