System and method for estimating material characteristics

摘要

A system for determining material characteristics of a material of a work surface includes a position sensor and a controller. The controller stores a first estimate of the material characteristics and utilizes a planning system to determine an expected profile. The expected profile is based at least in part upon the first estimate of the material characteristics. The controller determines an actual profile of the work surface, compares the expected profile to the actual profile, and determines a second estimate of the material characteristics based at least in part upon the difference between the expected profile and the actual profile.

1. A system for determining material characteristics of a material of a work surface, comprising:
a position sensor associated with a machine for generating position signals indicative of a position of the work surface; and a controller configured to:
store a first estimate of the material characteristics;utilize a planning system to determine an expected profile extending along a path, the expected profile based at least in part upon the first estimate of the material characteristics;receive a plurality of position signals from the position sensor as the machine moves along the work surface and a work implement of the machine moves a volume of material along the path;determine an actual profile of the work surface based at least in part upon the position signals;compare the expected profile to the actual profile; anddetermine a second estimate of the material characteristics based at least in part upon a difference between the expected profile and the actual profile.
