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.
