Full title and description

St ISO 17458-1-2013 — Road vehicles — FlexRay communications system — Part 1: General information and use case definition. This part of ISO 17458 provides the overall structure of the FlexRay series, common terminology and a set of representative use cases that illustrate where and how the FlexRay communications system is applied in road vehicles.

Abstract

ISO 17458-1:2013 gives an overview of the structure and partitioning of the ISO 17458 series and shows the relationships between the individual parts. It outlines typical use-case scenarios for FlexRay in automotive systems and defines terminology that is common across all parts of ISO 17458, establishing a baseline vocabulary and conceptual model for FlexRay-based network design and documentation.

Scope

This part describes the scope and organization of the ISO 17458 series and establishes use-case definitions where FlexRay is an appropriate communications solution for road-vehicle control applications. It does not specify protocol bit-level or electrical parameters (these are dealt with in other parts of the series); instead it defines the conceptual framework, terminology and typical application scenarios (for example time-triggered control, mixed synchronous/asynchronous traffic, and fault-tolerant topologies) to guide implementers and integrators.

Key topics and requirements

• Overview of the ISO 17458 series structure and relationships between parts.
• Definitions of common terminology and concepts used across FlexRay documents.
• Use-case descriptions showing where FlexRay is applicable in vehicle networks (time-triggered control, high-speed deterministic communication, mixed traffic patterns).
• Guidance on partitioning system functionality between synchronous (time-triggered) and asynchronous communication mechanisms.
• Reference to where detailed protocol, conformance and physical-layer requirements are specified (other parts of ISO 17458).

Typical use and users

Primary users are automotive system architects, vehicle network engineers, ECU and subsystem designers, test and verification teams, and standards/quality managers who need a consistent conceptual model and vocabulary for FlexRay deployments. Typical uses include early-phase design decisions, architecture and partitioning studies, supplier/customer communication about network-level requirements, and as a reference when mapping control functions to deterministic network resources.

Related standards

ISO 17458 is a multi-part standard for the FlexRay communications system. Key related parts include: Part 2 (Data link layer specification), Part 3 (Data link layer conformance test specification), Part 4 (Electrical physical layer specification) and Part 5 (Electrical physical layer conformance test specification). These parts contain the detailed protocol, test and electrical specifications that implementers and test houses will use alongside the overview and use cases found in Part 1.

FAQ

Q: What is this standard?

A: ISO 17458-1:2013 is the introductory part of the ISO 17458 series for the FlexRay communications system. It provides general information, common terminology and use-case definitions for FlexRay in road vehicles.

Q: What does it cover?

A: It covers the structure of the ISO 17458 series, use-case scenarios where FlexRay is appropriate, and standardized terminology to be used across the series. It does not give protocol-level or electrical specifications (these are in Parts 2–5).

Q: Who typically uses it?

A: Vehicle network architects, ECU and subsystem designers, test engineers, integrators, and standards/quality personnel who need a shared conceptual framework and vocabulary for designing or specifying FlexRay-based systems.

Q: Is it current or superseded?

A: The 2013 edition is the published edition for Part 1. ISO standards are subject to periodic review (typically every five years); users should consult ISO or their national standards body for the latest confirmed status or any amendments. As published information indicates the 2013 edition remains the reference edition for Part 1.

Q: Is it part of a series?

A: Yes — ISO 17458 is a multipart series. Part 1 is the general information and use-case definition; other parts provide the data link specification, conformance tests and physical-layer specifications and tests (for example Parts 2, 3, 4 and 5).

Q: What are the key keywords?

A: FlexRay, time-triggered, deterministic communication, in-vehicle network, ECU, data link layer, physical layer, conformance testing, automotive networking, ISO 17458.
