FLEET TELEMATICS

Fleet Telematics Systems (FTS) allow the information exchange between a commercial vehicle
fleet and their central authority, i.e. the dispatching office. A FTS typically consists
of mobile Vehicle Systems (VS) and a stationary Fleet Communication System (FCS). The
FCS may be a stand alone application maintained by the motor carrier or an internet service running
by the supplier of the system. The FCS usually includes a data base in which all vehicle
positions and messages are stored. Digital maps are often included which allow to visualise
vehicle positions and traces. The communication with the FCS is realised by
trunked radio, cellular, or satellite communication. Positioning of vehicles is usually realised
by satellite positioning systems and/or dead reckoning using gyroscope and odometer. Usually,
the VS is equipped with a simple input device allowing drivers to send predefined status
messages. Drivers may add simple content, e.g. numeric values, but usually cannot enter
arbitrary text. Besides of the messages sent by drivers, some VS can also automatically
submit messages, e.g. the vehicle’s position, data from sensors in the cargo body, or vehicle
data from the CAN-bus. In 2002 major European commercial vehicle manufacturers, namely
Daimler Chrysler, MAN, Scania, DAF, IVECO, Volvo, and Renault, have agreed to give third
parties access to vehicle data using the CAN-bus as a connection. The Fleet Management
Standard (FMS) is an open standard allowing, dependent on the vehicle equipment, access
to vehicle data such as fuel consumption, engine data, or vehicle weight.
