Full title and description

ISO 20077-1:2017 — Road vehicles — Extended vehicle (ExVe) methodology — Part 1: General information. This part defines concepts and terms related to the Extended Vehicle (ExVe) approach, presents general information and dedicated terminology, and describes how ExVe workstreams relate to other standards in the automotive domain.

Abstract

ISO 20077-1:2017 defines the key concepts and vocabulary for the Extended Vehicle (ExVe) methodology. It explains the extended vehicle concept, identifies the vehicle categories in scope (road vehicles with four or more wheels for carriage of persons or goods per UN Resolution No.1 definitions), and describes the interrelation with other standards addressing ExVe interfaces and services. The document notes that specification of particular interfaces or external test equipment is outside its scope.

Scope

Applies to road vehicles with four or more wheels designed primarily for carriage of persons (Category 1) or goods (Category 2) as defined in UN Special Resolution No.1. The standard provides general information and establishes terminology and relationships with related standards for ExVe; it does not standardize detailed interface or device implementations.

Key topics and requirements

• Definition of the Extended Vehicle (ExVe) concept and core terminology.
• Description of stakeholders and information flows between vehicle manufacturers, service providers and third parties.
• Clarification of which vehicle categories and development phases are in scope.
• Guidance on how ExVe-related standards interrelate (reference framework rather than technical interface specifications).
• Exclusions: does not mandate interface protocols, device specifications or implementation details for external test equipment.

Typical use and users

Used as a normative reference and conceptual foundation by vehicle manufacturers (OEMs), tier‑1 suppliers, telematics and service providers, regulatory and conformity-assessment bodies, testing laboratories, and engineers defining data-access and service‑provision processes for connected vehicles. It is primarily a vocabulary and methodology reference to align stakeholders when designing ExVe solutions and related specifications.

Related standards

ISO 20077 is a multipart deliverable. Relevant related documents include ISO 20077-2:2018 (Methodology for designing the extended vehicle), ISO/TS 20077-3:2024 (Upstream process to develop services), and work items for Part 4 (data structure description) under development. Complementary ISO work addressing ExVe web services and access/security includes the ISO 20078 series (web services: content/definitions, access, security) and related vehicle diagnostic/remote‑support standards such as ISO 20080. These related parts and documents together describe the conceptual, process and service layers of ExVe implementations.

FAQ

Q: What is this standard?

A: ISO 20077-1:2017 is Part 1 of the Extended Vehicle (ExVe) methodology series; it provides general information, definitions and the conceptual framework for ExVe.

Q: What does it cover?

A: It covers terminology, concepts, stakeholder relationships and the scope of ExVe activities for road vehicles (4+ wheels, passenger and goods categories). It explicitly does not define specific interface protocols or hardware devices.

Q: Who typically uses it?

A: OEMs, suppliers, telematics/service providers, testing labs, regulatory bodies and standards developers use it to align definitions and processes when designing or regulating ExVe‑based services.

Q: Is it current or superseded?

A: ISO lists ISO 20077-1:2017 as published and confirmed following its systematic review (the ISO catalogue indicates the standard was confirmed in 2023), so this edition remains current. Users should check ISO catalogue or national bodies for any later revisions.

Q: Is it part of a series?

A: Yes — ISO 20077 is a multipart deliverable. Key related parts include ISO 20077-2:2018 (design methodology), ISO/TS 20077-3:2024 (upstream process for service development), and further work items such as Part 4 (data structure description). The ISO 20078 series (ExVe web services) and ISO 20080 (remote diagnostic support) are also closely related.

Q: What are the key keywords?

A: Extended vehicle, ExVe, vehicle data, telematics, APIs, diagnostics, service provider, vehicle manufacturer, ISO 20077, ExVe methodology.
