IEC 63033-4:2022

Overview

IEC 63033-4:2022 is an international standard developed by the International Electrotechnical Commission (IEC). This standard is part of the IEC 63033 family focusing on multimedia systems and equipment for vehicles, specifically surround view systems. Part 4 of this series details the application of camera monitor systems (CMS), clarifying how composite images generated from multiple cameras must meet specified field of view (FOV) and display requirements, particularly those outlined in UN Regulation No. 46.

The goal of IEC 63033-4:2022 is to enhance indirect vision for drivers by defining standardized guidelines for the integration of surround view camera systems, ensuring both safety and regulatory compliance in modern vehicles.

Key Topics

• Composite Image Requirements: Outlines which camera views and image combinations are necessary for compliance and how their output must be managed.
• Field of View (FOV) Specification: Defines the FOV classes (I to VI) that must be captured by the surround view system, conforming to the requirements of UN Regulation No. 46.
• Display Requirements: Aligns with international vehicle regulations, ensuring camera monitor systems display the correct fields of view to support road safety.
• Obstruction Management: Specifies tolerances for physical and overlay obstructions within the required FOV for different mirror classes.
• Overlay Restrictions: Only temporary overlays are permitted, and overlays must not exceed 2.5% of the display area for a given FOV class.

Applications

IEC 63033-4:2022 is highly relevant for:

• Automotive OEMs: Standardizes the integration of surround view camera systems for compliance with safety regulations.
• Vehicle System Integrators: Ensures CMS solutions reliably replace or complement traditional mirrors under regulatory frameworks.
• Aftermarket Suppliers: Supports the design and installation of retrofitted camera monitor and surround view systems.
• Technical Inspectors and Regulatory Bodies: Provides benchmarks for assessing conformity with international indirect vision requirements.
• Software and UI Developers for In-Vehicle Displays: Guides the design of compliant user interfaces for composite camera images, aiming to improve driver awareness without causing distraction or obstruction.

Key practical values include:

• Enhancing driver situational awareness via panoramic and composite camera images.
• Facilitating safer maneuvering and parking by eliminating blind spots.
• Supporting innovation in driver assistance and autonomous vehicle technologies through standardization of image processing and display.
• Ensuring global regulatory compliance for vehicles equipped with advanced vision technologies.

• UN Regulation No. 46: Uniform provisions concerning the approval of devices for indirect vision and the installation in motor vehicles
• ISO 16505:2019: Road vehicles – Ergonomic and performance aspects of Camera Monitor Systems – Requirements and test procedures

Summary

Adopting IEC 63033-4:2022 is essential for organizations engaged in the design, manufacture, integration, or regulation of surround view systems and camera monitor systems for vehicles. This standard helps ensure that composite camera images contribute to safer roads, higher quality vehicle systems, and conformity with international standards. By following these guidelines, stakeholders support the ongoing evolution of vehicle safety technologies and driver assistance systems, enabling more reliable and effective indirect vision solutions.
