Figure 23.2.1 — Road vehicle to ITS technology chain

 

Six different areas of competence are part of the technology chain.

​

— Road vehicle technology:

This competence is provided by the vehicle manufacturers and their electronic system suppliers. They design vehicle's domain network architecture and connected ECUs. The diagnostic communication data of each ECU might be documented according to ISO 22901, the ODX standard, or traditionally in office type documents. The vehicle manufacturer is obliged to provide the ECU's diagnostic communication data in a non-discriminatory form to any interested party.

​

— Vehicle interface technology:

This competence is provided by the diagnostic tool suppliers. The V-ITS-SG has a similar type of functionality compared to today's Vehicle Communication Interfaces (VCI). Many VCIs support a wireless interface to communicate with remote Human Machine Interface (HMI) devices e.g. Nomadic Devices.

​

— ITS Host Applications & Mobile Routing technology (Vehicle-ITS-Station):

This competence is provided by the IT application and communication companies.

​

— Short and Wide Range Communication technology:

This competence is provided by the IT communication companies.

​

— ITS Host Applications & Mobile Routing technology (Roadside-ITS-Station):

This competence is provided by the IT application and communication companies.

​

— ITS Back Office technology (Central-ITS-Station):

This competence is provided by the ITS service provider companies.

The vehicle interface technology connects the road vehicle technology with the ITS technology via the Vehicle Mobile Gateway (V-ITS-SG) protocol. The V-ITS-SG protocol provides a single solution access method via standardized XML vehicle data transfer services.

​

The V-ITS-SG provides vehicle manufacturer/V-ITS-SG supplier controlled access to vehicle data and functions. The ND (Vehicle Station) software applications have a similar functionality compared to an Internet browser.

​

Work on developing these International Standards includes the identification of exisiting International Standards for nomadic devices and existing vehicle communication network access International Standards.

​

•  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 22837 defines the reference architecture for probe vehicle systems and a basic data framework for probe data.

• ISO 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.

 

The work also includes identifying further standardization requirements to support the provision of specific ITS services where provisions using nomadic devices have additional or different requirements than those for inbuilt communications media.

​

It also includes the provision of updating information from the passenger and the vehicle via nomadic devices to external service providers, and updating the nomadic device and/or the vehicle data systems, such as map updates, etc., and ensures that nomadic devices introduced into vehicles can be used safely to support ITS and multimedia services.

23.2.4    ISO TR 13184-1:2013   Intelligent transport systems (ITS) — Guidance protocol via personal ITS station for advisory safety systems — Part 1: General information and use case definitions

 

ISO 13184 consists of the following parts, under the general title Intelligent transport systems — Guidance protocol via personal ITS station for advisory safety systems:

​

— Part 1: General information and use cases definitions

The following parts are under preparation:

— Part 2: Road guidance protocol (RGP) requirements and specification

— Part 3: Protocol conformance test cases

 

This part of ISO 13184 specifies the requirements of a real-time decision support system for guidance information, designed to enhance mobility and vehicle safety and to provide a parking guide service using personal ITS stations. The purpose of the system is to transmit guidance or warning messages to drivers and pedestrians in real time, enhance the user’s convenience, and avoid congestion in parking facilities by preventing accidents and enabling easy parking.

​

In addition, an application level guidance protocol for crossroads, safety warning and parking bay guidance services between roadside ITS stations, installed at the road side, and user’s personal ITS stations, is defined.

​

This part of ISO 13184 considers a protocol, which covers all subjects related to traffic safety, including pedestrians and vehicle drivers. Therefore, this protocol describes how the safety-related services are provided using personal ITS stations.

​

This system is based on the following assumptions:

​

— Personal ITS stations have limited resources. Therefore, the protocol is designed in such way that it can be implemented with limited resources.

— The use cases related to the safety warning and parking bay guidance services can be classified in various ways. Also, these use cases can be enabled or disabled depending on the specific circumstances of roads and parking bays. Therefore, the protocol is designed to be flexible and extendable, which enables to add or delete use cases conveniently.

— The protocol contains core data elements to configure the messages transmitted by personal ITS stations and roadside ITS stations. The major use case includes safety warning at the road and the parking bay guidance.

— The protocol provided by this part of ISO 13184 does not take the network or transport level protocol into account. Instead, only the application level protocol for the safety warning and parking bay guidance services are presented.

 

Scope

This part of ISO 13184 specifies guidance information protocol to provide real-time decision support system to drivers or pedestrians using personal ITS stations:

• Reference architecture for the real-time decision support system

This reference architecture provides a general structure for real-time decision support systems and the method of message exchange between the personal ITS station and the roadside ITS station. This reference architecture is used to build the interconnections between personal ITS stations and roadside ITS stations.

• Design method of application protocols for light-weighted devices

This method is a flexible application protocol for safety warning and parking guidance services. Unlike many other application protocols in the ITS and Telematics domains, this protocol makes the client part independent of use cases for supporting light-weighted devices.

• Use cases at the road and parking bays for warning and parking guide

This part of ISO 13184 describes the use cases applicable to the communication services between personal ITS stations and roadside ITS stations for the purposes of providing safety warning and parking guidance.

 

​

ISO 13184 consists of the following parts, under the general title Intelligent transport systems (ITS) — Guidance protocol via personal ITS station for advisory safety systems:

— Part 1: General information and use cases definition

— Part 2: Road guidance protocol (RGP) requirements and specification

 

Additional part dealing with road guidance protocol (RGP) conformance test specification is under preparation.

​

This part of ISO 13184 specifies the use cases implementation of a real-time decision support system for guidance information, designed to enhance mobility and vehicle safety and to provide a parking guide service using the Personal ITS Station (P-ITS-S). The purpose of the system is to transmit guidance or warning messages to drivers and pedestrians in real-time, enhance the user’s convenience and avoid congestion in parking facilities by preventing accidents and enabling easy parking.

​

This part of ISO 13184 implements the road guidance protocol (RGP) requirements (derived from the use cases defined in ISO 13184–1) based on the Data eXchange Message (DXM) at the application level regarding the safety warning and parking guide services between the Roadside ITS Station (R-ITS-S) installed at the roadside and the user’s Personal ITS Station (P-ITS-S), e.g. Nomadic Device.

​

This part of ISO 13184 covers subjects related to traffic safety, including pedestrians besides vehicle drivers. Therefore, this DXM implementation describes how the safety-related services are provided using the P-ITS-S.

​

This system is based on the following assumptions:

— Based on the fact that the P-ITS-S has limited resources considers these limitations.

— Use cases related to the safety warning and parking guide service can be classified in various ways. These use cases can be added or deleted frequently depending on the specific circumstances of roads and parking spaces. Therefore, the DXM implementation design needs to be flexible and extendable, which enables to add or delete the use cases conveniently.

— The DXM implementation of road guidance contains data elements to configure the message transmitted between the ITS Stations.

— The major use cases include safety warnings at roads and parking guide services to be used between the R-ITS-S and the P-ITS-S.

​

Scope

This part of ISO 13184 specifies the road guidance use cases on the DXM to provide the real-time decision support system to drivers or pedestrians using P-ITS-S. The road guidance protocol (RGP) is an instantiation of the data exchange message (DXM), which represents a generic message to exchange data between ITS stations.

​

The RGP defines an interoperable service protocol between P-ITS-S and R-ITS-S for exchanging data elements.

 

This part of ISO 13184 specifies the following:

​

— Reference architecture for real-time decision support system.

This reference architecture provides a general structure for the real-time decision support system and the method of message exchange between the P-ITS-S and the R-ITS-S. This reference architecture is used to build the interconnections between the P-ITS-S and the R-ITS-S.

— Technique of application protocol design for various use cases on a P-ITS-S.

This technique adopts a flexible and extendable protocol design. In many cases, the application protocol for the ITS is designed to provide a set of messages that is dependent on the use cases and the message exchange method. However, it is not easy to enumerate all use cases for some applications. The use cases can be changed or enhanced frequently. For this type of application, the protocol design, depending on the use cases, is not appropriate. This part of ISO 13184 provides a general technique of designing the road guidance application protocol based on the use cases.

— Primitive data element.

The primitive data element will be commonly used to configure the safety warning and parking guide service in the form of speed, location and time.

— Use cases at the road and parking spaces for warning and parking guide.

This part of ISO 13184 describes the use cases applicable to the communication services between the P-ITS-S and the R-ITS-S for the purposes of providing safety warning and parking guidance.

ISO 13184 (all parts) have been aligned according to the requirements specified in ISO 21217, ISO/TS 17419 and ISO TS 17423.

​

This part of ISO 13184 only specifies the RGP messages based on the DXM definition (see Annex B and Annex C) at real-time. The content of the RGP messages are based on the definition of road guidance use cases as documented in ISO 13184–1.

​

This part of ISO 13184 implements ITS-SU objects, which is a general reference to ITS application objects, ITS message sets and other objects which may require globally unique identification and registration.

​

The management of ITS-SU objects is many-fold, e.g. specified in ISO 24102–4, ISO 24102–5, ISO 24102–6, ISO 24102–7, ISO 24102–8 and ISO 24102–9, and in CEN ISO TS 17423. This part of ISO 13184 implements authorized and controlled operation of ITS-SU objects, which requires considerations of ITS-SU object identifiers, i.e. ITS-AID, ITS-MsgSetID, ITS-SUID, ITS-SCUID, addresses and protocol identifiers used in the communication protocol stack of an ITS-S, and others.

​

NOTE The accuracy of the navigation and positioning system as input to the Road Guidance application is important for road guidance but is not part of the ISO 13184 series. Detailed information about crossroads is needed for implementation of Road Guidance applications.

​

To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.

 

This part of ISO 13185 can be used by vehicle manufacturers for future vehicle design to support the design of vehicle gateways to interface with NDs.

​

The ND applications need vehicle information data through an in-vehicle interface access method (V-ITS-S with V-ITS-SG).

​

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 to easily exchange vehicle information data among ND, vehicle V-ITS-SG, and ECUs.

​

The protocol implementation in the vehicle gateway features the following:

​

— the deny of access to the vehicle gateway data by unauthorized on-board and off-board test equipment;

— the deny of access to parts of the vehicle gateway data by unauthorized on-board and off-board test equipment (privacy);

— the identification of the vehicle gateway and the vehicle it is installed in;

— the list of in-vehicle connected ECUs to the vehicle gateway and their data parameters;

— methods to configure the access to vehicle data.

 

Scope

This part of ISO 13185 specifies the requirements of an ASN.1-based protocol between a vehicle-ITS-Station Gateway (V-ITS-SG) and a nomadic and/or mobile device (ND) to easily exchange vehicle information data.

​

The ASN.1-based protocol has been specified to support a wired or wireless connection between the ND and V-ITS-SG.

​

The Unified Gateway Protocol (UGP) is used between the V-ITS-SG and the ND. UGP supports several features in order to provide:

​

— authorization (data privacy),

— secured access,

— V-ITS-SG and in-vehicle ECUs identification,

— real-time vehicle data parameters with identifier and type information in ASN.1 format, and

— enhanced vehicle data parameters with identifier and type information in ASN.1 format.

 

23.2.10 ISO 13185-3:2018           Intelligent transport systems  — Vehicle interface for provisioning and support of ITS Services — Part 3: Unified vehicle interface protocol (UVIP) server and client API specification

 

This document has been established to define the UGP client and server Java API of a common software interface to a vehicle UGP server to easily exchange vehicle information data amongst nomadic and/or mobile devices, cloud servers, vehicle servers and the vehicle's Electronic Control Units (ECUs).

Applications supporting service provision use via nomadic and mobile devices need vehicle information data through an in-vehicle interface access method as well as the harmonization of existing standards to support a single vehicle data access solution.

​

A Nomadic Device (ND) becomes a Personal ITS station (P-ITS-S) if a Hardware Security Module (HSM) and software, that prohibits unauthorized access to an ITS-secured domain inside the ND, has been implemented.

​

This document defines the UGP client and server Java API protocol between the P-ITS-S and the UGP server in the vehicle.

​

The protocol specified in this document is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.

​

This document may be used by vehicle manufacturers to implement an interoperable UGP server in on-board communications modules that are allowed to interface with P-ITS-S(s). Through this interface, P-ITS-S(s) can access in-vehicle information provided to the UGP server. The means by which the UGP server obtains the in-vehicle information is outside the scope of this document.

​

The P-ITS-S applications need vehicle information data through an in-vehicle interface access method.

This document supports ITS applications based on a client-server model which allows clients on P-ITS-S to obtain data from ECUs in the in-vehicle networks (IVNs) through a common interface to a server located in a Vehicular ITS station (V-ITS-S) which in turn is acting as a gateway to the IVNs. The protocol implementation in the vehicle's UGP server may include the following features:

​

— the denial of access to the vehicle's UGP server data by unauthorized on-board and off-board test equipment;

— the denial of access to parts of the vehicle's UGP server data by unauthorized on-board and off-board test equipment (privacy);

— the identification of the vehicle's UGP server and the vehicle it is installed in;

— the list of in-vehicle connected ECUs to the vehicle's UGP server and their data parameters;

— methods to configure the access to vehicle data.

 

Scope

 

This document specifies the server and client APIs of the Unified Gateway Protocol (UGP). Figure 1 shows an overview of the UGP client and server API. A UGP client application on a P-ITS-S communicates with a UGP server application on a V-ITS-S. The UGP client application implements the UGP client API using ISO 13185-2. The UGP server application implements the UGP server API using ISO 13185-2.
