ISO/TS 7815-1:2025 インテリジェント交通システム — ITS ステーションを使用した規制商用貨物車両 (TARV) 用のテレマティクス アプリケーション — Part 1:安全な車両インターフェイスのフレームワークとアーキテクチャ | ページ 6

3.1

application service

service provided by a service provider accessing data from the in-vehicle system (IVS) of a regulated commercial freight vehicle via a wireless communications network

3.2

appoint

assign officially to take responsibility for a role

3.3

architecture

formalized description of the design of the structure of the telematics applications for regulated commercial freight vehicles secure vehicle interface (TARV-SVI) and its framework

3.4

controller area networking bus

CAN bus

network designed for use in automotives

Note 1 to entry: See ISO 11898-1, ISO 11898-2 and ISO 11898-3 for further information.

Note 2 to entry: CAN uses a single terminated twisted pair cable and is multi-master. The maximum signal frequency used is 1 Mbit/s, with a typical length of 40 m at 1 Mbit/s up to 10 km at 5 Kbit/s.

Note 3 to entry: CAN has high reliability with extensive error checking. The typical maximum data rate achievable is 40 KB/s. The maximum latency of a high priority message < 120 µs at 1 Mbit/s.

Note 4 to entry: CAN is unusual in that the entities on the network, called nodes, are not given specific addresses. Instead, it is the messages themselves that have an identifier which also determines the messages' priority. For this reason there is no theoretical limit to the number of nodes, although in practice it is approximately 63.

3.5

certificate authority

<digital> organization which issues digital certificates for use by other parties, specifically in the context of communications security

3.6

commercial application

intelligent transport systems (ITS) application in regulated commercial freight vehicles for commercial (non-regulated) purposes

3.7

framework

particular set of beliefs or ideas referred to in order to describe a scenario or solve a problem

3.8

global navigation satellite system

GNSS

several networks of satellites that transmit radio signals containing time and distance data that can be picked up by a receiver, allowing the user to identify the location of its receiver anywhere around the globe

[SOURCE:ISO 15638-1:2012, 4.21, modified —"comprises" has been removed from the beginning of the definition.]

3.9

in-vehicle system

IVS

intelligent transport system (ITS) station and connected equipment on board a vehicle

3.10

jurisdiction

government, road or traffic authority which owns the regulatory applications

3.11

map

spatial dataset that defines the road system

3.12

on-board unit

OBU

integrated telematics unit installed on board which provides the specified telematics functionality required for the in-vehicle system (IVS)

3.13

regulated application

regulatory application approval arrangement utilized by jurisdictions for granting certain categories of commercial vehicle rights to operate in regulated circumstances subject to certain conditions

Note 1 to entry: Each jurisdiction may use their own terminology including, but not limited to,"permit","application","scheme","concession","exemption","gazettal" and"notice".

3.14

regulated application service

telematics applications for regulated commercial freight vehicles (TARV) application service that is mandated by a regulation imposed by a jurisdiction, or an option supported by a jurisdiction

3.15

regulated commercial freight vehicle

vehicle (often but not always designed to haul commercial freight) that is subject to regulations determined by the jurisdiction as to its use on the road system of the jurisdiction in regulated circumstances, subject to certain conditions, and in compliance with specific regulations for that class of vehicle

Note 1 to entry: Jurisdictions can choose to require the provision of information via telematics applications for regulated commercial freight vehicles (TARV) or provide operators with the option to do so.

3.16

specification

explicit and detailed description of the nature and functional requirements and minimum performance of equipment, service or a combination of both

3.17

Unified Modeling Language

UML

graphical language for visualizing, specifying, constructing and documenting the artifacts of a software- intensive system

Note 1 to entry: UML offers a standard way to write a system's blueprints, including conceptual elements such as business processes and system functions as well as concrete elements such as programming language statements, database schemas, and reusable software components, and is standardized as ISO/IEC 19501.

3.19

user

party that makes use of the vehicle
