CEN/TS 17249-4:2019 (E)
Introduction
As a result of European Regulation, from 2018, all new model Category M1/N1 vehicles will be equipped
with112-eCall. Other model Category M1/N1 vehicles may be voluntarily equipped with 112-eCall.
The current eCall Regulation covers only M1 and N1 Category vehicles (cars and vans). The European
Commission’s “ICT Rolling Plan (2017) states the objective “Action 1 Develop technical
specification/standards for the implementation of eCall in vehicles of categories other than M1 and N1
and for other user types, taking into account requirements included within type approval regulation as
well as ongoing activities in this area (pilots, CEF,…).” And goes on to explain “…….for the extension to
other vehicles types and services, such as Heavy Duty Vehicles, Power Two Wheelers or Hazardous Goods
tracking, and other classes of vulnerable road users”.
The CEN Project TC 278 PT1507 has addressed the issues relating to eCall for HGVs, coaches and busses,
Powered two wheel vehicles and agricultural/forestry vehicles. See CEN/TR 17249-1:2018 for context
(especially Section 12 in respect of agricultural/forestry vehicles).
The UNECE category T defines an agricultural/forestry vehicle as “a power-driven vehicle, either wheeled
or track laying, which has at least two-axles, whose function depends essentially on its tractive power,
and which is specially designed to pull, push, carry or actuate certain implements, machines or trailers
intended for use in agriculture or forestry. Such a vehicle may be arranged to carry a load (E.g.:
Forwarder) and attendants.”
When on the road, accidents involving agricultural/forestry vehicles can cause serious problems, largely
because of what they are towing (muck spreaders, equipment with metal spikes, large round bales,
livestock, etc.) and while it may be impractical to know the cargo, it is important to know that it is an
agricultural/forestry vehicle and that such related problems may arise.
However, in the case of agricultural/forestry vehicles of most types, the benefit of eCall off the roadway
is of even greater value. The agricultural/forestry vehicle driver is normally working alone, with no
passing traffic or onlookers, frequently in a remote location. If there is a serious incident and the
agricultural/forestry vehicle driver is injured, this is often not noticed for some considerable time. It is
already well recognized that eCall is of greatest benefit to speed assistance to those who have incidents
in remote locations. (That said, it is recognized that eCall, as currently supported, will only work where
there is cellular network coverage, however, CEN/TS 17312 is addressing this issue to additionally
provide eCall support via satellite communications for those who elect to add this capability, and TS
17184 provides the means to support eCall via IMS (4G/LTE) communications where this capability is
supported by the nearest PSAP and the vehicle is suitably equipped).
This Technical Specification provides determination for the provision of 112-eCall to
agricultural/forestry vehicles. As with the existing provisions for eCall for Category M1/N1 vehicles,
these systems are specified within the paradigm of being OEM fit equipment supplied with new vehicles.
The provision of eCall for the aftermarket will be the subject of other work, and in respect of the
operational requirements for any such aftermarket solutions for agricultural and forestry vehicles will
use the specifications of this Technical Specification as a principle reference point.
This document is complementary to EN 16072 and EN 15722 and presents adaptation requirements for
the provision of eCall for Agricultural and Forestry vehicles.

1 Scope
In respect of 112-eCall (operating requirements defined in EN 16072), this document defines additional
specifications for the provision of eCall for agricultural/forestry vehicles.
As with the existing provisions for eCall for Category M1/N1 vehicles, these systems are specified within
the paradigm of being OEM fit equipment supplied with new vehicles.
NOTE 1 The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of
other work, and in respect of the operational requirements for any such aftermarket solutions for
agricultural/forestry vehicles, will use the specifications of this Technical Specification as a principle reference
point.
NOTE 2 The 112-eCall paradigm involves a direct call from the vehicle to the most appropriate PSAP. (Third
party service provision by comparison, involves the support of an intermediary third party service provider before
the call is forwarded to the PSAP). The specifications herein relate only to the provision of 112-eCall or IMS-112-
eCall, and do not provide specifications for third party service provision of eCall.

6 General overview of the eCall session for 112-eCall for agricultural and
forestry vehicles
6.1 Context of Agricultural/forestry vehicle accidents
See CEN/TR 17249-1:2018 Clause 12 for greater detail concerning typical agricultural and forestry
vehicle accidents.
Accidents related to agricultural and forestry vehicles can be related to the working accidents which
happen e.g. in the field or traffic accidents which happen in the public roads.
Upon a serious accident or collision, the IVS shall trigger the 112-eCall automatically, in accordance with
EN 16072, and the relevant wireless cellular communication standard for eCall, in the case of an eCall
equipped agricultural/forestry vehicle (3.3), also providing a relevant set of “Optional Additional Data”
as part of the minimum set of data in accordance with EN 15722 and as defined in this specification.
An eCall can also be generated manually in accordance with EN 16072 and the specifications defined
herein.
In the case of agricultural/forestry vehicles (3.3), there are the following specific use cases in addition to
data requirements defined in EN 15722:
• Rollover detection: Upon accident, the IVS shall detect and report the rollover, and optionally may
detect the type of rollover (side roll-over or rear roll-over)
• Vehicle operator information: Upon accident, the PSAP operator shall be informed if the person
operating the vehicle was present in the cabin.
NOTE An accident can happen when the agricultural/forestry vehicle is operating but the operator is not
present in the cabin. Also, an agricultural/forestry vehicle can be in a self-driving mode.
• Implement list: The PSAP operator can be made aware about the context of type of the work
performed by agricultural/forestry vehicle (if known).
See CEN/TR 17249-1:2018, Clause 12 for detail.
6.2 Agricultural and Forestry vehicle categories defined by UNECE
See CEN/TR 17249-1:2018, Clause 12 for detail. In summary:
UNECE classifies agricultural/forestry vehicles as Category T, R and S:
• 'Category T' means any motorised, wheeled or tracked agricultural or forestry vehicle having at least
two axles and a maximum design speed of not less than 6 km/h
8

---------------------- Page: 10 ----------------------

SIST-TS CEN/TS 17249-4:2019
CEN/TS 17249-4:2019 (E)
• 'Category R - Agricultural trailer' means any agricultural or forestry vehicle intended mainly to be
towed by a tractor and intended mainly to carry loads or to process materials
• 'Category S - Interchangeable towed equipment': any vehicle used in agriculture or forestry which is
designed to be towed by a tractor, changes or adds to its functions, permanently incorporates an
implement or is designed to process materials
NOTE Quadricycles used frequently in agriculture are Categorized under category L6e and L7e. eCall for
category L6e and L7e are covered by CEN/TS 17249-6.
6.3 Device (implement or machine) classes defined by ISOBUS
The following device classes are defined by ISOBUS dictionary referred to in ISO 11783-10, which may
act as agricultural/forestry vehicle implements (3.8). An agricultural/forestry vehicle may perform
different operations and have different kinds of implement connected. In order to give a context of type
of work performed by the agricultural/forestry vehicle to the PSAP operator, if this information is known
and made available to the vehicle eCall IVS (3.9), the IVS may report information about types of connected
devices as part of its ‘Optional Additional Data’ (3.14).
The means by which such data are made available to the IVS is a feature of in-vehicle system design and
outside the scope of this specification.

7 General requirements
7.1 Automatic / manual eCall triggering
An eCall may be automatically or manually triggered as specified in EN 16072.
If an agricultural/forestry vehicle is equipped for eCall, the system shall include rollover detection as
defined herein.
7.2 Triggering conditions
The conditions for triggering of eCall, as described in EN 16072:2015, Clause 7.10, shall also apply to eCall
for agricultural/forestry vehicle UNECE Category T).
UNECE Category R and S trailers may, if appropriate, be fitted with a manual eCall device, or be connected
to the Category T towing vehicle eCall device using the CANBUS or similar means.
NOTE Category R and S trailers can house machinery powered by the PTO connection of the attached Category
T towing vehicle or be powered for other means, such as wood shredding, timber sawing and other timber
processing, baling, cutting, harvesting etc. which carry risks to the driver/operator and are a cause of injury and
death, often in a remote location. A manual eCall triggering device such as a strategically located button or some
sensor activated automatic trigger can therefore be provided for Category R and S trailers.
Instigation of triggering and the technical means of triggering, in this OEM provided paradigm, shall be
determined by the designer of the system, however such provisions shall trigger an eCall in the event of:
– Significant collision
– Rollover
– Fire
– Other conditions considered appropriate by the system designer
– Manual instigation
“Significant collision” in this paradigm are the conditions that the system designer determines should
generate an eCall.

7.4.2 Agricultural vehicle ‘AV1’optional additional data concept ‘Object Identifier’
The object identifier uniquely identifies the format and meaning of the data which follows in the optional
additional data concept as defined in EN 15722.
eCall has been allocated the OID 1.0.14817.106.2.1. Within this, arc ‘.2’ has been defined to contain
‘Optional additional data concepts’. The OID for the OAD named ‘AV1’ shall be 1.0.14817.106.2.1.2.4.
This deliverable defines first version of the schema for ‘AV1’ which consequently shall be identified by
this unique OID:

For further detail regarding the use of OIDs in eCall, see EN 15722.
7.4.3 Agricultural/forestry vehicles optional additional data concept ‘AV1’
The OAD shall be called the “Agricultural Vehicle OAD” or “AV1” for brevity.
Table 2 provides a summary of the semantic contents of the optionalAdditionalData part of the MSD for
AV1. Embedding the OAD is optional, but when embedded the mandatory elements noted in Table 2 shall
be provided. Optional elements shall not be embedded when the IVS has no means to determine their
value.
The sequence of data presentation shall be as specified in Table 2, represented and distributed as
described in EN 15722.
For clarity the ‘type’ used in Table 2 is a semantic representation of the type used in the ASN.1 definition.
The exact representation is found in Annex A.
The real position of the element in the data-stream is defined by the ASN.1 ‘unaligned packet encoding
rules (uPER), following the definition in Annex A. Elements therefore do not necessarily start or end on a
byte boundary.
