Intelligent transport systems - eSafety - Part 4: eCall for UNECE Category T, R, S agricultural/forestry vehicles

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.

Intelligente Verkehrssyteme - eSicherheit - Teil 4: eCall für UNECE-Kategorie T, R und S Landmaschienen und Forstfahrzeuge

Im Hinblick auf 112-eCall (betriebliche Anforderungen entsprechend EN 16072) legt diese Zielvorgabe Europäischer Normen zusätzliche Spezifikationen für die Bereitstellung von eCall für Fahrzeuge der Land- und Forstwirtschaft fest.
Wie bei den bereits bestehenden Bestimmungen zu eCall für Fahrzeuge der Kategorie M1/N1 werden diese Systeme innerhalb des Paradigmas spezifiziert, dass es sich um eine Ausrüstung handelt, die vom Originalgerätehersteller in Neufahrzeuge eingebaut wird.
ANMERKUNG 1 Die Bereitstellung von eCall für Fahrzeuge über den Nachrüstmarkt (nach Verkauf und Zulassung) wird den Gegenstand einer anderen Arbeit bilden, die im Hinblick auf die betrieblichen Anforderungen für derartige Nachrüstlösungen für Fahrzeuge der Land- und Forstwirtschaft diese Technische Spezifikation als Hauptanhaltspunkt verwenden wird.
ANMERKUNG 2 Das 112-eCall-Paradigma beinhaltet einen Direktanruf vom Fahrzeug bei der zuständigen Notrufzentrale (en: Public Safety Answering Point, PSAP). (Zum Vergleich: Die Diensterbringung durch Dritte beinhaltet die Unterstützung eines zwischengeschalteten externen Dienstleisters, bevor der Anruf an die PSAP weitergeleitet wird.) Die folgenden Spezifikationen beziehen sich nur auf die Bereitstellung von 112-eCall oder IM-112 eCall und sind enthalten keine Spezifikationen für die eCall-Diensterbringung durch Dritte.

Inteligentni transportni sistemi - e-Varnost - 4. del: e-Klic za kmetijska/gozdarska vozila UN/ECE kategorij T, R, S

V zvezi s storitvijo e-Klic 112 (zahteve za delovanje so določene v standardu EN 16072) ta dokument določa dodatne specifikacije za zagotavljanje e-Klica za kmetijska/gozdarska vozila.
Tako kot obstoječe določbe za e-Klic za vozila kategorije M1/N1 so tudi ti sistemi opredeljeni v okviru paradigme, da gre za originalno nameščeno opremo (OEM), ki je dobavljena z novimi vozili.
OPOMBA 1: Zagotavljanje e-Klica za vozila po naknadni vgradnji (po prodaji in registraciji) bo predmet drugih dokumentov. V okviru zahtev za delovanje za katere koli take naknadne rešitve za kmetijska/gozdarska vozila bodo specifikacije te tehnične specifikacije uporabljene kot glavna referenčna točka.
OPOMBA 2: Primer e-Klica 112 je neposredni klic iz vozila do najustreznejšega centra za usklajevanje reševanja (zagotavljanje storitev drugih ponudnikov – za primerjavo – vključuje podporo posredniškega drugega ponudnika storitev, preden je klic posredovan centru za usklajevanje reševanja). V tem dokumentu navedene specifikacije se nanašajo samo na zagotavljanje e-Klica 112 ali e-Klica 112 IMS in ne podajajo specifikacij za zagotavljanje storitve e-Klic drugega ponudnika.

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
---------------------- 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.

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.

Table 2 — Contents/format of Commercial vehicle additional data AV1
M – Mandatory data field (ie. mandatory if this encoding scheme is used)
O – Optional data field.
optionalAdditionalData
oid RELATIVE OID M Fixed value: 4.1
data encoded as OCTET STRING
rolloverSignal ENUM M Indicates if rollover has been detected by IVS
(3.9). Rollover is when the vehicle orientation
has changed by more than 90o
The supported values are:
noRolloverDetected
rolloverDetected
rolloverDetectionUnclear
NOTE: Considering agricultural accident data
this is considered the most important
information (both indicating the accident type
and severity to the PSAP operator) and may
have impact on emergency response action.
operatorInVehicle ENUM O Indicates if vehicle’s operator was present in the
vehicle at the moment of eCall triggering.
The supported values are:
- notInVehicle
- inVehicleNoSeatbeltInfo
- inVehicleSeatbeltFastened
- inVehicleSeatbeltNotFastened
- automatedVehicleWithoutOperator
NOTE: this information can be used by the PSAP
to assert the condition of the operator.
implementList O List of at maximum 3 connected implements
NOTE: the contents of this data element gives
context about the type of work performed to the
PSAP, that might be useful in the assessment of
the severity of the incident.
implementType[1] ENUM M NOTE: the enumeration is derived from the
ISOBUS dictionary which follows
ISO 11783-11.and can be found in the ASN.1
definition in the Annex.

(normative)
Definition of OAD for Agricultural/Forestry Vehicles
A.1 General

As soon as the OID has revealed the nature of the data as being AV1 (using the standard eCall MSD

message definition, see EN15722) the data from the optionalAdditionalData block can be decoded. Either

by applying the definition of the datablock to that data
A.2 ‘Agricultural Vehicle’ AV1 OAD ASN.1 definition

This module definition is appropriate for transmission of the OAD “Agricultural Vehicle” (AV1).

MSD_ADDITIONAL_AV1

– Definition of the eCall related OAD message for Agricultural/Forestry Tractors in ASN.1

– Any OAD message will encoded using this scheme, following the
– UPER encoding rules.
