Project duration January 2013 - August 2017
Status Completed
Venture Transport Efficiency

Purpose and goal

The main purpose of the project has been to develop novel method to find the optimal machine operation in combined work cycles, typically a mission carried out by several cooperating machines. The project has also aimed at developing a demonstrator to test these novel methods under real-life conditions.

Expected results and effects

A novel method to optimise an off-road transport mission towards minimum fuel consumption has been developed. The targeted transport mission involves one wheel loader and 2 articulated haulers transporting e.g. gravel or grit at a set production rate [ton/h] which could be chosen arbitrarily. The develed method has in a demonstrator environment shown a fuel efficiency potential on roughly 9% of the machines involved. Apart from the technical results the project has also resulted in an increased knowledge and a couple of scientific papers as well as internal technical reports.

Planned approach and implementation

A twofold method is utilised. To create the tools needed in the optimal control a literature study of available methods are performed and then models and algorithms are developed on “the desktop” and verified against recorded data. As a second step a human machine interface demonstrator is built, enabling the evaluation of how the control inputs are received by the operator and potential fuel efficiency gains achieved.
