In this report various future trends are listed for mobile machinery diagnostics. Standards, legislation, sensors, vehicle networks, data-analysis and prognostics are discussed. Mobile machinery diagnostics are studied from two points of view: process industry condition monitoring and automotive vehicle diagnostics. Some standards for these industries are listed. Sensor discussion is mainly from an automotive point of view and vehicle networks are targeted towards wireless communication. The data-analysis part includes basics of neural networks, fuzzy systems and genetic algorithms. Bayesian networks are also covered into some depth. In the end an example of modern vehicle diagnostic system is presented.
