rFMS explained: live truck positions without fitting a box

What rFMS is

rFMS, the remote Fleet Management System standard, was agreed by the major European truck makers so that one piece of software can read vehicle data from trucks of different brands in the same way. The truck sends its data to the maker's cloud; the carrier gives its TMS access to that cloud.

Which makers offer it

Scania, Volvo Trucks, Renault Trucks, DAF and MAN all provide rFMS access, usually as part of their connected services. Some fleet platforms also expose their data through rFMS. Access is requested from the maker for the trucks you own or lease.

What data a carrier gets

• Position, heading and speed, reported every few minutes.
• Odometer, for maintenance and for charging by the kilometre.
• Fuel level and consumption, where the truck reports them.
• Engine and driving data, depending on the maker and the contract.

Why it matters for dispatch

Knowing where a truck really is changes how a dispatcher works. An ETA can be judged against the truck's actual position rather than the driver's last message, and a late arrival is visible before the customer calls. The odometer comes straight from the vehicle, so nobody has to read it off the dashboard.

What to watch for

Telematics data arrives in reports, not as a continuous stream. A good TMS shows how old each position is, and marks a truck as delayed when it stops reporting, instead of drawing it as if it were current. A position from forty minutes ago should never look like a live one.

How Truvio uses it

Truvio reads Scania through its own interface and Volvo Trucks, Renault Trucks, DAF, MAN or any rFMS provider through the standard. Each truck reports to its maker's cloud and appears on the live fleet map with its speed, odometer and fuel, with nothing fitted in the cab. A truck that stops reporting is shown as delayed where it was last seen. For trucks without rFMS, the driver app reports the run's progress from the driver's phone.
