Alanen J. Diagnostics of mobile work machines

In this research note, we take a look at the field of mobile work machinediagnostics. The perspective by the authors is limited by the research project
(KODIE) behind this research. However, we have tried to provide generic guidelines for machine builders to set up their diagnostics strategy. Building
blocks, like SAE J1939/73, ISO 15765 and ODX, from automotive industry are
exhibited to prevent machine manufactures from reinventing diagnostics
protocols and practices. Furthermore, examples of diagnostics architectures are
presented, with OSA-CBM among others. To make the most of diagnostics data,
an extensive set of data analysis methods are introduced. And in order to help
engineers to design diagnostics feature for the sensor system, hints and examplesare supplied as to how to establish the fault modes of sensors; a good knowledge
about the (relevant) sensor and actuator fault modes is a prerequisite for
comprehensive fault detection.
