Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no longer
valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TR 13185-1 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

Introduction
This part of ISO 13185 specifies the requirements for a common software interface to a vehicle gateway
to easily exchange vehicle information data among nomadic and/or mobile device, vehicle gateway and the
vehicle’s ECUs.
Applications supporting ITS service provision and multimedia use via nomadic and mobile device need a
common access method to vehicle data through an in-vehicle interface as well as the harmonization of existing
standards to support a single vehicle data access solution.
This document defines a vehicle data transfer protocol between vehicle gateway also called V-ITS-SG and the
nomadic and/or mobile device (ND).
This part of ISO 13185 may be used by vehicle manufacturers for future vehicle design to support the design
of ITS/Telematics and as a retrofit equipment for aftersales vehicles.
Applications supporting ITS service provision and multimedia use via ND may be implemented using vehicle
information, driver advisory, warning systems and entertainment systems. The following standards are subject
to analysis in regard to their applicability to supporting ITS service provision and multimedia use via nomadic
and mobile device.
— ISO 15031 defines emissions-related diagnostic data supported by vehicles in all countries requiring
OBD compliance.
— ISO 27145 WWH-OBD defines diagnostic data (emissions-related systems, future safety related systems,
etc.) to be supported by vehicles in all countries implementing the GTR (Global Technical Regulation) into
their local legislation.
— ISO 22900-2 defines the Modular Vehicle Communication Interface (MVCI) D-PDU API to separate the
protocol data unit (PDU) from the vehicle specific protocols.
— ISO 22901 defines the Open Diagnostic data eXchange (ODX) format which is a standard for describing
diagnostic related ECU data. This International Standard is becoming the vehicle manufacturer’s choice to
document vehicle system diagnostic data and protocol information.
— ISO 22902 is a multimedia and telematics standard based on the AMI-C specification and reference
documents for automotive industry. The important logical element of the architecture is a vehicle interface.
— ISO 22837 defines the reference architecture for probe vehicle systems and a basic data framework
for probe data.
— ISO/TS 29284 defines the standardization of information, communication and control systems in the
field of urban and rural surface transportation, including intermodal and multimodal aspects thereof,
traveller information, traffic management, public transport, commercial transport, emergency services
and commercial services in the ITS field.
— SAE J2534 defines a standardized system for programming of ECUs in a vehicle.
— SAE J2735 defines the support of interoperability among DSRC applications through the use of standardized
message sets, data frames and data elements.
This part of ISO 13185 supports ITS applications which are based on ND in vehicles to operate on a common
software interface to a V-ITS-SG integrated within the CALM architecture and easily exchange vehicle
information data among ND, V-ITS-SG and ECUs.

5.2 Purpose of this Technical Report
The main purpose of this Technical Report is to:
a) Identify the requirements of bidirectional vehicle data transfer,
b) Identify the usability of the existing International Standards for nomadic and mobile devices and existing
vehicle communication network access standards,
c) Identify additional work required to develop the common software interface to a vehicle gateway integrated
within the CALM architecture by the amendment of the existing interface to D-PDU API in the provision
and support of ITS services via nomadic and mobile devices.
5.3 ITS communication architecture components
The ITS communication architecture is a communication system designed for ITS and made of four physically
separated subsystem components:
— the vehicle subsystem component: Vehicle ITS Station (Vehicle ITS-S),
— the nomadic and mobile subsystem component: Personal ITS Station (Personal ITS-S),
— the roadside subsystem component: Roadside ITS Station (Roadside ITS-S),
— the central subsystem component: Central ITS Station (Central ITS-S).
Figure 2 illustrates the connection between the Personal and Vehicle ITS Station. The V-ITS-S consists of:
— the V-ITS-S Router supporting the CALM architecture, and
— the V-ITS-S Host and Gateway to the in-vehicle networks.

NOTE The V-ITS-SG is not a part of the Vehicle ITS Station.
The scope of this Technical Report is V2N (or N2V). V2N is the abbreviation used to cover all types of
communication between vehicle and nomadic and mobile devices.
There are many existing International Standards for the communication between Vehicle ITS Station and
Personal ITS Station for bidirectional vehicle data transfer.
There is a need to identify the usability of the existing International Standards for nomadic devices and existing
vehicle communication network access standards.
6 Vehicle interface standardization
6.1 Overview of relevant standards
Various standards exist which are applicable to either the vehicle network or ITS infrastructure. The following
is a summary of applicable standards:
— ISO 15031 (all parts) defines emissions-related diagnostic data supported by vehicles in all countries
requiring legislative OBD compliance. This International Standard defines a diagnostic connector and
facilities which should be provided by an external test tool. ISO 15031 (all parts) also specifies the diagnostic
6 © ISO 2012 – All rights reserved

---------------------- Page: 10 ----------------------
ISO/TR 13185-1:2012(E)
messages and DTCs (Diagnostic Trouble Codes) which are reported by the vehicle to the external test tool.
It specifies additional details of the diagnostic message format and communication for the ISO 9141-2,
ISO 14230-4 and SAE J1850 protocols. ISO 15031-5 supersedes those protocol standards.
— ISO 27145 (all parts) defines diagnostic data (emission-related systems, future safety related systems) to
be supported by vehicles in all countries implementing the GTR (Global Technical Regulation) into their
local legislation. The ISO 27145 series includes the definitions for a common data dictionary, provides
data definitions for emissions-related legislated diagnostics (reference to SAE J1930-DA, SAE J1979-
DA, SAE J2012-DA) and common message dictionary, provides the message implementation details
from ISO 14229-1 and ISO 14229-2, Unified Diagnostic Services (UDS) to support the required legislated
WWH-OBD. It also defines the details necessary to implement the communication between the vehicle’s
WWH-OBD systems and external test equipment including the definition/reference of physical layers, data
link layers, network layer, transport layer and session layer.
— ISO 22837 defines the reference architecture for probe vehicle systems and a basic data framework for
probe data. The basic data framework provides an initial set of probe data elements which are commonly
used in typical probe data enabled application domains, such as traffic, weather, and safety. The basic
data framework provides example probe messages, which define how probe data elements are combined
to convey information to a probe processing centre.
— ISO 22900-2 defines the Modular Vehicle Communication Interface (MVCI) D-PDU API to separate the
protocol data unit (PDU) from the vehicle specific protocols. This part of ISO 22900 is becoming the
diagnostic tool supplier’s choice to separate diagnostic data conversion and application test logic from the
vehicle communication.
— ISO 22901 (all parts) defines the Open Diagnostic data eXchange (ODX) format, which is a standard for
describing diagnostic related ECU data. This series of International Standards is becoming the vehicle
manufacturer’s choice to document vehicle system diagnostic data and protocol information.
— ISO 22902-5 and ISO 22902-6 define a multimedia and telematics standard based on the AMI-C
specification and reference documents for the automotive industry. The important logical element of the
architecture is a vehicle interface. The vehicle interface is defined as a component that provides access
to vehicle services from an AMI-compliant network. It may act as a gateway to the in-vehicle manufacturer
defined network or it may implement some or all of the vehicle services directly.
— ISO/TS 29284 defines the probe data format that is sent from vehicles depending on particular events.
The proposed Technical Specification defines events for, e.g. fog, snowfall, and accidents.
— SAE J2534 defines a standardized system for programming that includes a standard personal computer
(PC), standard interface to a software device driver, and an interface that connects between the PC and a
programmable ECU in a vehicle.
— SAE J2735 defines the interoperability among DSRC applications through the use of standardized message
sets, data frames and data elements. This International Standard provides the messages sets, data frames
and data elements to produce interoperable DSRC applications between Road Side Equipment (RSE) and
On-Board Equipment (OBE).
6.2 Standardized vehicle interface
6.2.1 Vehicle interface for ITS applications
Each International Standard (ISO 22837, ISO/TS 29284 and SAE J2735) defines messages sets, data frames
and data elements to produce interoperable ITS applications between Vehicle Station and Roadside Station.
Figure 4 illustrates that these International Standards do not include the access method to ‘1’ and ‘2’ from the
vehicle manufacturer’s in-vehicle network (vehicle domain architecture).
IMPORTANT — The vehicle interface does not include a standardized access method to data elements
from the in-vehicle network.
