Full title and description

Road vehicles — Visibility — Method for establishment of eyellipses for driver's eye location. This International Standard specifies a statistical, elliptical (eyellipse) model and procedures for locating drivers' eyes inside road vehicles to support visibility and driver's field-of-view assessments.

Abstract

This document establishes three‑dimensional eyellipse models representing tangent cut‑off percentiles of driver eye locations and gives procedures to construct 95th and 99th percentile tangent cut‑off eyellipses for a 50/50 gender mix of the adult user population. It also defines neck pivot (P) points for adjustable‑seat eyellipses to derive specific left/right eye points for direct and indirect viewing tasks. The standard applies to Class A (passenger cars, multipurpose passenger vehicles and light trucks) and Class B (heavy trucks) vehicles.

Scope

ISO 4513:2022 specifies methods to determine the spatial distribution of drivers' eye positions using eyellipse models (in 2D/3D) for use in visibility and field‑of‑view measurements. It provides construction procedures for 95th and 99th percentile tangent cut‑off eyellipses for an adult population with a 50/50 gender mix, defines neck pivot (P) points for adjustable seats, and indicates applicability to Class A and Class B road vehicle types. The procedures support standardizing driver eye locations for design and regulatory visibility assessments.

Key topics and requirements

• Definition and construction of 3D eyellipse models representing driver eye‑location percentiles (95th and 99th tangent cut‑off).
• Procedures for establishing eyellipses for adjustable‑seat vehicles and fixed‑seat applications.
• Definition of neck pivot (P) points and derivation of specific left/right eye points for viewing tasks (aligned with SAE viewing task conventions).
• Application to Class A (passenger cars, MPVs, light trucks) and Class B (heavy trucks) vehicles.
• Use of eyellipse data as a design tool and for harmonized field‑of‑view/regulatory measurements.

Typical use and users

Vehicle designers and engineers (body, seating and exterior design), visibility and human factors specialists, test laboratories performing field‑of‑view and visibility checks, type‑approval and regulatory bodies, and standards developers use ISO 4513 to define standardized driver eye positions for design validation, laboratory testing and regulatory assessment. OEMs use the eyellipse procedures to ensure compliance with visibility requirements and to optimize driver sightlines.

Related standards

ISO 4513:2022 updates and replaces earlier editions (for example ISO 4513:2010 and the withdrawn 2003 edition). It references industry practices for viewing tasks such as SAE J1050 and vehicle classification conventions such as SAE J1100 (and leverages definitions used in ISO 3833 for certain vehicle classes). Users often consult complementary standards on seating, anthropometry and vehicle visibility when applying eyellipse methods.

FAQ

Q: What is this standard?

A: ISO 4513:2022 is an International Standard that specifies methods for establishing statistical eyellipse models and locating drivers' eyes inside road vehicles to support visibility and field‑of‑view assessments.

Q: What does it cover?

A: It covers construction procedures for 95th and 99th percentile tangent cut‑off eyellipses (3D), definitions of neck pivot (P) points for adjustable seats, and application guidance for Class A and Class B vehicles. The standard is intended for use in design, testing and regulatory measurement of driver visibility.

Q: Who typically uses it?

A: Vehicle OEMs, seating and exterior designers, human factors engineers, test laboratories, certification authorities and standards bodies involved in vehicle visibility and ergonomics.

Q: Is it current or superseded?

A: Current — ISO 4513:2022 is the active (published) edition that supersedes earlier editions such as ISO 4513:2010 and prior versions.

Q: Is it part of a series?

A: It is a stand‑alone ISO technical standard within ISO/TC 22 (road vehicles) work on visibility and ergonomics; it complements other vehicle‑related standards (e.g., those addressing seating, anthropometry and visibility test methods) rather than being a numbered series.

Q: What are the key keywords?

A: eyellipse, driver eye location, visibility, field of view, neck pivot, percentile, Class A vehicles, Class B vehicles.
