ISO 15638-9:2020

Overview

ISO 15638-9:2020 - "Intelligent transport systems - Framework for cooperative telematics applications for regulated commercial freight vehicles (TARV) - Part 9: Remote digital tachograph monitoring" defines a standardized framework for remote digital tachograph monitoring (RTM). It specifies the form, content and access methods for transmitting digital tachograph data to support regulatory and enforcement systems for regulated commercial freight vehicles. The standard applies to digital tachographs and IVS (in‑vehicle systems) - it is not applicable to analogue tachographs.

Key technical topics and requirements

• Service definition and realization: High‑level description of the RTM application service (what a service provider delivers) and options for how jurisdictions can adopt it without mandating instantiation details.
• Data naming, content and quality: Standardized data elements, content profiles and quality requirements for tachograph data delivered by IVSs; profiles recognize jurisdictional limits on what may be transmitted over the air.
• Communication profiles: Defines multiple communications options to support remote inspection:
  • Profile C1 - Short‑range roadside inspection initiating a physical roadside check (master/slave): C1a (hand‑held/temporary), C1b (vehicle‑mounted interrogator), C1c (permanent/semi‑permanent roadside or gantry).
  • Profile C2 - Short‑range interrogator that downloads data to an application service provider (master/slave + peer‑peer): C2a, C2b, C2c (same sub‑variants as C1).
  • Profile C3 - Remote inspection via ITS‑station initiating a wireless download to an application service provider (per ISO 15638‑2).
• Quality of service, testing and conformance: Provisions for QoS, test requirements, approval of IVSs and service providers, audits, and software engineering quality systems.
• Security and access control: Requirements for information security, data access control policies and jurisdictional approval arrangements.
• Operational concepts: Roles and responsibilities (jurisdiction, approval authority, prime service provider, application service provider, user), sequences of operation, and service elements for RTM deployment.

Practical applications and users

ISO 15638-9 supports practical implementations for:

• Regulators and enforcement agencies seeking standardized remote inspection and compliance checks.
• Telematics and application service providers designing RTM back‑office services and data exchanges.
• Vehicle OEMs and IVS manufacturers implementing compliant on‑board systems and data interfaces.
• Fleet operators and hauliers who contract RTM services or need to comply with jurisdictional monitoring.
• Testing labs and conformity assessment bodies performing approvals, audits and interoperability tests.
