Create an exchange of Vehicle Identification Number, VIN over CAN between trailer and truck.
Background.
Modern fleet owners want to know the unique identification of their tractors and
trailers. It is used for optimizing their logistic services by their ERP software platforms,
but also for immediate operational intervention if a tractor is coupled to an incorrect
trailer.
The preference is to use the full Vehicle Identification Number (VIN, having 17
characters), because that is the only identification in the Western world that is
standardized, legalized and verifiable by comparing it to the vehicle type plate.
Action points
DOITS proposed to ACEA’s TF HDEI FMS standardisation group to support
the introduction of a functionality to enable exchange of trailer and truck VIN over CAN.

TF HDEI confirmed a wish to get trailer VIN transmitted over CAN to be delivered via rFMS to the truck and requested DOITS to provide a specification of what shall the truck ask the trailer to pick up the trailer VIN?

Feedback from TF HDEI October 16:th 2018.
-TF HDEI confirms there is a common wish to capture the Trailer VIN to be able to
deliver this to 3:rd parties via FMS and/or rFMS.
-The quality of ID data from the trailer i.e. the VIN is poor today and correct VIN is only
possible to capture from maybe 10-15% of the existing trailer fleet.
-TF HDEI is positive to that DOITS work on increasing the penetration of existing
trailers, manufactured from 2007 and forward, to deliver the correct VIN.
- TF HDEI has no objections against using the proposed standards to establish the
communication of VIN from the trailer to the truck
Next step
A key to make this exchange of VIN over CAN a significant contribution to the transport
industry is to be able to implement this functionality also into the existing fleet of trailers.
Necessary technology is already on board in the EBS (Electronic Brake Systems) delivered to trailers
manufactured from 2007 and onward.
To deliver the benefits it is decisive to tap in the correct VIN number into the trailers
EBS systems. Today there is a too low quality of the VIN data in the older systems
(trailers delivered before 2015) and these have to be upgraded with the ambition to
cover an AS HIGH PROPORTION OF EXISTING EUROPEAN TRAILERS AS POSSIBLE.
To achieve this it requires a co-operation between trailer manufacturers, EBS suppliers
and other parties involved in maintaining and servicing trailers.
DOITS HAVE TAKEN ON THE CHALLENGE TO COORDINATE AND OPTIMIZE THE
IMPLEMENTATION OF CORRECT VIN NUMBER IN THE TRAILERS EBS SYSTEMS.
