Subject(s): Abstract: Syfte och mål: The goal is to deliver: - a planning algorithm for the integrated task of remote diagnostics and workshop diagnostics. - a methodology for modeling the systems and distributed functions of the vehicle using Bayesian networks. - a methodology for adding driver and mechanic actions and observations to a Bayesian network model. - a prototype platform, a model of a selected system, and an integration of the model, a diagnostic inference engine, and the planner algorithm. Förväntade effekter och resultat: It will become necessary to have a computerized troubleshooting support system with guided diagnostics to help the mechanic. The current project will investigate how such guided diagnostics should be built for heavy-vehicle workshops. The troubleshooting problem is not isolated to the workshop. Instead we need to consider the whole chain, ranging from that a fault is detected on-board the vehicle, to that the vehicle is repaired and leaves the workshop. Planerat upplägg och genomförande: The project contains a research part and a prototyping part. The research part is mainly a continuation of ongoing PhD-projects for two PhD students in collaboration with Linköping University. The prototyping part aims to apply all of the project results to a real system and build a demonstration system with the purpose of being a major input to an industrialization of the results.
