ISO 22133:2026 PDF

Overview

ISO 22133:2026, titled "Road vehicles - Test object monitoring and control for active safety and automated/autonomous vehicle testing - Functional requirements, specifications and communication protocol," is a key international standard published by ISO. It specifies requirements, procedures, and message formats for the monitoring and control of test objects used in the testing of active safety and autonomous vehicle functions. By providing a unified communication protocol, ISO 22133:2026 enables interoperable testing environments where control centers can safely manage test objects from multiple vendors.

This standard is crucial for anyone involved in developing, testing, or certifying technologies related to active safety and automation in road vehicles. It ensures consistency, safety, and interoperability during the orchestration and execution of complex automotive test scenarios on proving grounds and other controlled environments.

Key Topics

• Functional Requirements: Defines the necessary features and performance criteria for test object control and monitoring systems.
• Communication Protocol: Specifies standardized message formats and protocols that enable seamless communication between the control centre and various test objects, regardless of the manufacturer.
• Test Object Types: Covers both moveable and stationary test objects, such as vehicles, pedestrians, bicyclists, and infrastructure elements.
• Control Centre Functionality: Describes the responsibilities of the centralized or distributed control centre, including scenario execution and safety monitoring.
• Safety and Risk Assessment: Details requirements and recommendations for geofencing, emergency stops, and risk mitigation during tests.
• Time and Coordinate Systems: Standardizes coordinate reference frames and time synchronization methods for precise scenario execution and data logging.
• Monitoring Functionalities: Outlines real-time status and positional monitoring, as well as heartbeat and diagnostic messages.
• Scenario and Trajectory Handling: Specifies methods for both static (pre-planned) and dynamic (real-time created) trajectory communication.

Applications

ISO 22133:2026 is directly applicable in the following contexts:

• Automated Vehicle Testing: Enables accurate, safe, and interoperable testing environments for autonomous vehicles by providing uniform protocols for test object control.
• Active Safety Function Development: Supports the evaluation and validation of advanced driver assistance systems (ADAS), including collision avoidance and emergency braking.
• Multi-vendor Test Setups: Facilitates collaborative testing with test objects and equipment from different suppliers, ensuring compatibility and standardized data exchange.
• Proving Ground Operations: Standardizes the setup and execution of complex, multi-actor traffic scenarios, improving reliability and repeatability of safety assessments.
• Scenario-based Simulation and Testing: Informs software-in-the-loop (SiL) and hardware-in-the-loop (HiL) testing that demands synchronized interactions between control centers and test objects.
• Regulatory and Certification Testing: Provides a foundation for independent or third-party testing organizations to perform consistent assessments according to international requirements.
