The Fleet Managment System (FMS) is a standard interface to vehicle data of commercial vehicles. In 2002, six large European truck manufacturers decided to develop the open FMS-standard for their clients: DAF Trucks, Daimler AG (Mercedes-Benz), IVECO, MAN AG, Volvo (including Renault and Scania). The FMS translates vehicle data to the J1939 protocol which is developed by the Society for Automotive Engineers (SAE). If FMS data is combined with the J1939 data, such as GPS position, Tachograaf data, sensor readings, a universal communication and information source arises: the FMS CANbus.

The following data is broadcast at the FMS interface of the truck brand and standardised to SAE J1939 so you can use a single system supporting mixed fleets.

  • Accelerator pedal position (0–100%)
  • Axle weight (kg)
  • Brake switch (on/off)
  • Clutch switch (on/off)
  • Cruise control (on/off)
  • Engine coolant temperature
  • Engine speed
  • FMS-Standard software version (supported modes)
  • Fuel level (0–100%)
  • High-resolution vehicle distance
  • Power take-off (PTO) (Status/Mode)
  • Service distance
  • Tachograph information
  • Total engine hours (h)
  • Total fuel used (litres since lifetime)
  • Vehicle identification number (ASCII)
  • Vehicle improvement (all round)
  • Vehicle speed (wheel based)
  • Vehicle speed (from tachograph)
