ESPRIT Project 8487 OMI/CARGOTRACK had an objective of implementation of a pan-European fleet management system oriented to the European truck transportation industries. The responsibility of INESC/INOV consisted in the design of a flexible communications controller that could be applied to any fleet management system. Being constructed within the scope of the Open Microprocessor Initiative (OMI), the controller has integrated ARM60 RISC microcontroller. The partners of INESC in this project were PDV (consulting), Kuhne&Nagel (truck transportation company), BIBA (research institute), PAN DRIVE (vehicle control) and TECMIC (design and development of integrated circuits).
