ISO 15622-2018 PDF

Full title and description

Intelligent transport systems — Adaptive cruise control systems — Performance requirements and test procedures. This International Standard defines system‑level performance requirements, minimum functionality, driver‑interface elements, diagnostics and failure reactions, and standardized test procedures for Adaptive Cruise Control (ACC) systems, including Full Speed Range ACC (FSRA) and Limited Speed Range ACC (LSRA) implementations.

Abstract

ISO 15622:2018 specifies how ACC systems should behave and be tested at the system level. It covers basic control strategy and states, following and “go” transitions, minimum driver interface requirements, diagnostics and safe‑fallback behavior, and performance test methods (test targets, environmental conditions and test procedures). The standard is intended for longitudinal control on highways and (for FSRA) congested traffic including stop/hold/resume behaviour.

Scope

ISO 15622:2018 applies to Adaptive Cruise Control systems implemented for longitudinal vehicle control on roads where non‑motorized traffic and pedestrians are prohibited (primarily highways). It defines FSRA and LSRA categories, minimum functionality (set speed, time‑gap following, target acquisition and following), limits on response to stationary/slow objects, and system behaviour for stop/hold/resume (FSRA). It also standardizes performance test procedures, test target specification and environmental conditions for evaluation.

Key topics and requirements

• Classification of ACC types: Full Speed Range ACC (FSRA) and Limited Speed Range ACC (LSRA) with subtypes.
• Basic control strategy and defined system states (off, stand‑by, active, speed control, following, FSRA hold).
• Minimum functionality: set speed, time‑gap following, target acquisition and following capability, and “go” transition behaviour.
• Driver interface requirements: operation elements, displays and symbols (references ISO symbol guidance).
• Diagnostics and failure reactions: fault detection, safe fallback (handover to driver), activation of brake lights and other safety responses.
• Performance evaluation: standardized test procedures, environmental test conditions, and test target specifications for radar/LIDAR systems.

Typical use and users

Used by automotive OEMs, Tier‑1 ADAS suppliers, test laboratories, homologation and regulatory bodies, and research organisations. Typical activities include system design and validation of ACC features, development of driver displays and diagnostics, type‑approval and compliance testing, and integration of ACC into broader partially automated driving functions.
