Full title and description

Intelligent transport systems — Forward vehicle collision warning systems — Performance requirements and test procedures. This International Standard specifies performance requirements and test procedures for forward vehicle collision warning systems (FVCWS) intended to warn drivers of potential rear‑end collisions with vehicles ahead in normal driving conditions.

Abstract

ISO 15623:2013 defines the operating envelope, performance criteria, warning modalities and systematic test procedures for FVCWS operating within specified subject‑vehicle speed ranges and road curvature limits. It covers service on roads with curve radii greater than 125 m and applies to motor vehicles including cars, trucks, buses and motorcycles; responsibility for safe operation remains with the driver.

Scope

Specifies performance requirements and standardized test procedures for systems that provide driver warnings to help avoid or mitigate rear‑end collisions. Performance and test methods address detection, target discrimination, warning timing, human–machine interface (visual, auditory, haptic), and system operating limits (including minimum curve radius >125 m). The standard is intended for assessment of FVCWS in ordinary driving conditions and defines the measurement and evaluation methods used to verify compliance.

Key topics and requirements

• Definition and classification of FVCWS classes and operating envelopes (speed ranges, curve radius limits).
• Detection and sensing performance: target detection, relative position/velocity measurement, and target discrimination requirements.
• Warning logic and HMI: timing of preliminary and imminent‑collision warnings; permitted modalities (visual, auditory, haptic) and guidance to avoid nuisance alerts.
• Quantified test procedures: test target specifications, environmental/test conditions, detection zone and warning distance evaluations, and performance metrics.
• Limitations and safety notes: statement that driver retains responsibility and that system limits must be documented in user information.

Typical use and users

Automotive OEMs, sensor and system suppliers, test laboratories, regulatory bodies and conformity assessment organizations use ISO 15623:2013 to specify, design, evaluate and validate forward collision warning functions. The standard is also used by researchers and ITS architects when comparing FCW performance or integrating FCW behavior with other active safety systems (e.g., ACC, AEB).

Related standards

ISO 15623:2013 replaces the earlier ISO 15623:2002. Closely related documents and series commonly referenced alongside ISO 15623 include ISO 15622 (adaptive cruise control performance), SAE human‑factors reports such as SAE J2400, and other ITS active‑safety standards (lane‑departure and lane‑change performance standards, and test‑device standards such as the ISO 19206 series). These documents are frequently used together when defining integrated active safety or advanced driver assistance system (ADAS) testing programs.

Keywords

FAQ

Q: What is this standard?

A: ISO 15623:2013 is an International Standard that specifies performance requirements and test procedures for forward vehicle collision warning systems (FVCWS).

Q: What does it cover?

A: It covers system classification, detection and sensing performance, warning logic and human‑machine interface requirements, quantified test methods (including test targets and environmental conditions), and operating limits such as road curve radius and speed ranges.

Q: Who typically uses it?

A: Automotive manufacturers, ADAS/sensor suppliers, test houses, regulators and researchers use the standard to design, validate and benchmark forward collision warning functions.

Q: Is it current or superseded?

A: ISO 15623:2013 supersedes ISO 15623:2002. The 2013 edition is the published (current) version of the standard; users should check with ISO or their national standards body for any amendments or later revisions.

Q: Is it part of a series?

A: Yes—ISO 15623 sits within a family of ITS/vehicle active‑safety standards (for example ISO 15622 for ACC and various lane‑departure/lane‑change standards) and is commonly used alongside human‑factors and test‑device standards when developing or validating ADAS.
