The Fleet Management System Interface (FMS) is the standard interface for commercial vehicle vehicle data. Six European manufacturers Daimler AG, MAN AG, Scania, Volvo (including Renault), DAF Trucks and IVECO developed the so-called FMS-Standard in 2002 to make independent plant applications for telematics possible.
The following data is broadcast in the FMS interface:
- Enhanced vehicle (all rounds)
- Vehicle speed (by wheel)
- Vehicle speed (from tachograph)
- Coupon button (on/off)
- Brake switch (on/off)
- Roaming controls (on/off)
- PTO (Status/Mode)
- Accelerator pedal position (0-100%)
- The amount of fuel used (liter since age)
- Fuel rate (0-100%)
- Machine speed
- Gross axle weight rating (kg)
- Total machine hours (h)
- Version of the FMS-Standard software (supported mode)
- Vehicle identification number (ASCII)
- Tachograph information
- High resolution vehicle distance
- Distance service
- Coolant temperature
Data is encoded according to SAE J1939. The data repetition rate is between 20 ms (for example engine speed) and 10 seconds (eg vehicle identification number).
By FMS standards it is now possible to have independent apps and evaluations from the manufacturer.
The amount of data depends on the manufacturer and model of the vehicle and may be different. If some data is not available in the interface, they are marked as unavailable.
According to records from truck manufacturers, the FMS standard is seen as a worldwide standard. Direct connection to the internal vehicle bus system is not permitted by the truck manufacturer and may result in loss of warranty. Meanwhile, some manufacturers are very limited in their workshops and cut off all unknown connections to the internal bus system.
According to ACEA ca. 160,000 vehicles were equipped with FMS standard interfaces in 2007. The FMS standard is also the basis for Bus-FMS-Standards for buses and coaches published in 2004.
