GOST R ISO 11898-1-2015 PDF

Full title and description

GOST R ISO 11898-1-2015 — "Road vehicles. Controller area network (CAN). Part 1. Data link layer and physical signalling" — a Russian national adoption (GOST R) of the international ISO 11898-1:2015 standard that specifies the CAN data link layer and physical signalling, including provisions for Classical CAN and CAN FD frame formats.

Abstract

This standard defines the Controller Area Network (CAN) data link layer and physical signalling, covering logical link control (LLC), medium access control (MAC) and physical coding sub-layer behaviour. It documents the Classical CAN frame format (up to 1 Mbit/s and up to 8‑byte payload) and the CAN Flexible Data Rate (FD) frame format (higher bit rates and extended payloads), and provides options for implementations that support or tolerate CAN FD.

• Number of pages: Listed vendor copies of the GOST R text show approximately 42 pages (packaged national publication). ISO edition metadata for ISO 11898-1:2015 indicates 65 pages for the international document.

Scope

The standard specifies the characteristics required to set up interchange of digital information between modules using the CAN data link layer. It covers the architecture (DLL and physical coding sub-layer), LLC and MAC sublayers, frame formats (Classical CAN and CAN FD), error handling, arbitration, frame timing and signalling conventions necessary for interoperable CAN implementations in road vehicles and related control applications. Note: the international ISO 11898‑1:2015 edition has been subsequently revised by ISO 11898‑1:2024, which expands the family (for example to include CAN XL).

Key topics and requirements

• Definition of CAN frame formats: Classical CAN (standard and extended identifiers) and CAN FD (flexible data-rate frames with extended payload lengths).
• Logical Link Control (LLC) and Medium Access Control (MAC) sublayer behaviours: arbitration rules, bit timing, frame sequencing and acknowledgements.
• Physical coding sub-layer signalling and bit-level encoding required for interoperable messaging on a CAN bus.
• Implementation options: classical-only, tolerant-to-FD, and full FD-support implementations, and recommendations for new designs to support newer formats.
• Error detection and confinement, frame error handling and bus fault behaviour to ensure robustness in automotive environments.
• Compatibility considerations where mixed networks (Classical CAN, CAN FD, and later CAN XL) may interact and interoperability constraints that designers must observe.

Typical use and users

This standard is used by automotive and vehicle electronics designers, ECU manufacturers, embedded systems engineers, transceiver and controller IC vendors, test laboratories, and certification bodies. It is referenced when developing or validating CAN controllers, transceivers, bus architectures, vehicle network diagnostics and higher-layer protocols that rely on the CAN data-link behaviour (for example, diagnostics and vehicle communications stacks).

Related standards

ISO 11898 series and other CAN-related standards commonly referenced with GOST R ISO 11898-1-2015 include: ISO 11898-2 (high-speed physical medium attachment / physical layer), ISO 11898-3 (low-speed fault-tolerant MDI), ISO 11898-4 (time-triggered communication), and higher-level or conformance documents (for example ISO 16845 and CiA recommendations for CAN XL). Note that ISO 11898-1:2015 has been revised by ISO 11898-1:2024 which adds CAN XL and other updates; corresponding parts of the ISO 11898 family were also updated in 2024.

FAQ

Q: What is this standard?

A: GOST R ISO 11898-1-2015 is the Russian national publication of the international ISO 11898-1:2015 standard that defines the CAN data link layer and physical signalling for vehicle networks (Classical CAN and CAN FD frame formats).

Q: What does it cover?

A: It covers the logical link control and medium access control sublayers, frame formats and signalling rules, arbitration and error handling, and physical coding conventions needed for interoperable CAN implementations. The 2015 edition incorporated CAN FD; later ISO revisions (2024) further expanded the standard family (for example to include CAN XL).

Q: Who typically uses it?

A: Vehicle OEMs, ECU and embedded systems designers, semiconductor vendors (CAN controllers and transceivers), test labs, integrators and standards compliance assessors use this document when implementing, testing or validating CAN bus functionality.

Q: Is it current or superseded?

A: The GOST R publication corresponds to the ISO 11898-1:2015 edition; internationally ISO 11898-1:2015 has been superseded/revised by ISO 11898-1:2024. Users should check whether their projects require the 2015 text (for legacy compatibility) or the 2024 edition (for CAN XL and newest features).

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 11898 series (CAN). Other related parts include ISO 11898-2 (high-speed physical layer), ISO 11898-3 (low-speed fault-tolerant MDI), ISO 11898-4 (time-triggered communication), and additional conformance/higher-layer documents in the CAN ecosystem.

Q: What are the key keywords?

A: CAN, CAN FD, Controller Area Network, data link layer, physical signalling, LLC, MAC, physical coding sub-layer, GOST R, automotive networks.
