Diagnostics and Prognostics via Telematics for Commercial Vehicles: On-Board Systems

The introduction of wireless communications capability into vehicles provides a means to offer new services centered on remote monitoring, diagnostics and prognostics for vehicle systems linked to the communications channel. This paper examines some important elements of on-board system design necessary to provide these services and indicates how they might be linked into an off-board “decision center” to provide effective services for commercial vehicles.
