IVHM examines the vehicle health against the vehicle usage data and within the context of similar information for other vehicles within the fleet. In use vehicles display unique usage characteristics and also some characteristics common across the fleet. Where usage data and system health data is available these can be analysed to identify ...
Highly developed fleet management and vehicle telematics systems collect a full range of data in real-time and for transport and fleet managers. By combining received data from the vehicle tracking system and the on-board computer, it is possible to form a profile for any given driver (average speed, frequency of detours, breaks, severity of ...
The Fleet Management Systems Interface (FMS) is a standard interface to vehicle data of commercial vehicles. The six European manufacturers Mercedes-Benz, MAN, Scania, Volvo (including Renault), DAF and Iveco developed the so-called FMS-Standard in 2002 to make manufacturer-independent applications for telematics possible.
