Proactive Dozing Control logic: Interprets data, makes decisions to mirror seasoned operator

When Komatsu unveiled its revolutionary intelligent Machine Control system in 2013, the integrated, mast- and cable-free, semi-automated GPS program promised increased production and precision grading. It delivered, and now Komatsu is taking the technology to another level with Proactive Dozing Control logic.

“The first iteration of intelligent Machine Control was a starting point,” explained Komatsu Product Marketing Manager Derek Morris. “Once that was accepted in the market and became a viable part of a construction site, we focused on how to make it better.”

To do that, Komatsu designed its Proactive Dozing Control system to more closely resemble an experienced operator during initial rough-cut applications – a point when operators were not utilizing intelligent Machine Control.

“Traditionally, end users were only using automation to perform final grade,” noted Morris. “That happened because the system would work to get the blade to grade as soon as possible, creating aggressive cuts that could stall a machine. During that phase, experienced operators would typically cut and carry large but manageable loads, so they could move the material to other parts of a jobsite. We added this logic and practice.”

The result is an intuitive technology that delivers productivity gains of within 6 percent of an experienced operator.

“Proactive Dozing Control logic tracks, collects and interprets terrain data and then makes decisions based on that information,” said Morris. “It can now calculate when to cut and when to carry material, while also allowing the operator to provide input on where the blade should be based on existing ground. The new system enables the operator to use automatics in applications such as stripping topsoil or spreading fill.”

‘Grass to grade’

With Proactive Dozing Control logic, operators are able to use the technology at all times, boosting efficiency and productivity.

“Using machine control exclusively for fine grading meant it was utilized only 10 to 20 percent of the time,” said Morris. “Proactive Dozing Control logic gives Komatsu intelligent Machine Control dozers grass-to-grade automatics, which delivers greater return on investment.”
