Full title and description

ISO 20077-2:2018 — Road vehicles — Extended vehicle (ExVe) methodology — Part 2: Methodology for designing the extended vehicle. This part of the ISO 20077 series specifies rules, basic principles and templates that an extended vehicle (ExVe) manufacturer should use when designing ExVe functionality and when responding to requests for new ExVe services.

Abstract

ISO 20077-2:2018 defines general rules and basic principles that an extended vehicle (ExVe) manufacturer considers when developing its design methodology for ExVe functionality. It provides templates for the information to be supplied by a requester when asking for a new ExVe functionality and for the information the ExVe manufacturer provides in response. The document applies to the design and production phases (including subsequent design upgrades of models/variants still in production) and is independent of the communication interface used between ExVe and external systems. It does not standardize internal vehicle communications nor prescribe software or hardware implementation details.

Scope

This part of ISO 20077 specifies the methodology for designing extended vehicle (ExVe) functionality. It sets out the essential information elements and templates to be exchanged between requesters (service providers, third parties, internal stakeholders) and the ExVe manufacturer when proposing and designing new ExVe services. The standard applies irrespective of the external communication interface chosen, and covers design and production phases including later design upgrades of vehicles still in production. It excludes internal ExVe communications and does not mandate specific hardware or software implementations.

Key topics and requirements

• Principles and general rules for an ExVe manufacturer's design methodology (high-level requirements and constraints).
• Template for requester information — the minimum information a requester should supply when asking for a new ExVe functionality.
• Template for response information — the information the ExVe manufacturer should provide when responding to a request.
• Applicability to vehicle design and production phases, including subsequent design upgrades of models and variants.
• Independence from specific external communication interfaces — the methodology applies regardless of transport or protocol choices.
• Explicit exclusion of internal vehicle communication details and implementation choices for software/hardware.
• Guidance that the standard remains applicable should new remote communication interfaces become mandatory.

Typical use and users

Primary users are vehicle manufacturers (OEMs) and their engineering teams responsible for ExVe architecture and product design. Secondary users include automotive suppliers, system integrators, telematics and connectivity platform providers, third‑party service providers requesting vehicle data or functions, regulatory and compliance teams, and consultants involved in vehicle data access policies and service development.

Related standards

ISO 20077-1:2017 (Extended vehicle — General information) — establishes concepts and terminology for ExVe. ISO/TS 20077-3 (Upstream process to develop services) provides related upstream process guidance. Work items and technical specifications under the 20077 series (for example data-structure and API guidance in later parts/work items) and related ISO 20078 series (ExVe web services — content and definitions) and ISO/TR 23791 (risk assessment on ExVe web services) are relevant for implementers seeking a complete ExVe framework.

A: ISO 20077-2:2018 is Part 2 of the Extended Vehicle (ExVe) methodology series; it defines the methodology and templates used when designing ExVe functionality and when exchanging requests and responses between requesters and an ExVe manufacturer.

Q: What does it cover?

A: It covers high-level rules, principles and information templates for requesting and designing ExVe services during vehicle design and production phases. It does not define internal vehicle communication protocols or mandate implementation details.

Q: Who typically uses it?

A: Vehicle manufacturers (OEMs), suppliers, telematics and platform providers, third-party service developers, and regulatory/compliance stakeholders involved in vehicle data access and service design.

Q: Is it current or superseded?

A: The document was published on 3 January 2018 (Edition 1). It is part of an active series and was subject to periodic review; implementers should check the latest ISO catalogue or national standards bodies for any amendments, related technical specifications or newer parts in the 20077 series.

Q: Is it part of a series?

A: Yes — ISO 20077 is a multi-part series addressing the Extended Vehicle (ExVe) methodology. Part 1 provides general information; Part 2 covers design methodology; subsequent parts/technical specifications address related processes, data structures and service development steps.
