In this talk I will present the "Truck Fleet Management" blueprint which is focused on capitalizing on the data generated by a fleet of trucks. Fleet managers want to be able to capture and make use of a vehicle’s position, current speed and other details. This problem domain is already addressed by commercial vendors offering Fleet Management System (FMS) software-as-a-service , mostly using vendor and vehicle specific telematics units ("black boxes") which need to be installed to the vehicle to extract data and transmit to a cloud back end. Clients of such solutions often complain about hardware and software vendor lock-in, which results in high costs for adding vehicles of additional brands and/or migrating to a different FMS vendor. In this talk I will first introduce the overall problem domain and relevant industry standards like FMS and J1939. I will then illustrate how fleet managers can reduce the total cost of ownership by leveraging COVESA VSS and open source software produced by members of the Eclipse Software Defined Vehicle working group. I will also talk about recent developments and next steps regarding the convergence of the work of different organizations engaged in the Commercial Vehicle domain like COVESA, AEAC, FMS and SAE. If time permits, I also will showcase the system in action, transferring vehicle data to a cloud back end from where the information can be retrieved using rFMS or visualized in a Grafana dashboard.
