IEC 63033-3:2019

Overview

IEC 63033-3:2019 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies measurement methods for drive monitoring systems used in car multimedia equipment. This standard complements IEC TS 63033-1:2017, which defines the system models and general requirements for such systems. Drive monitoring systems enhance driver safety by providing real-time images of a vehicle’s surroundings using external cameras, enabling dynamic viewpoints suited to varying driving situations through “free eye point” technology.

This standard plays a vital role in ensuring consistent, reliable measurement and verification of system performance criteria such as camera resolution, image quality, calibration, field of view, and system response timing. It supports automotive manufacturers and system integrators in validating drive monitoring systems for safety, regulatory compliance, and ergonomic efficiency.

Key Topics

System Model

The standard outlines a system model where cameras mounted externally on the vehicle generate composite or single images. The system captures multiple fields of view essential for comprehensive drive monitoring. Measurements reference ISO 16505 and UN Regulations No. 46 and No. 125 related to camera monitor systems and driver field of vision but do not require full compliance with these regulations.

Camera Image Quality

• Resolution: Cameras used in the system must have a minimum resolution of 300,000 pixels.
• Image Quality: Image quality requirements for both cameras and monitors adhere to ISO 16505:2019 standards. Specific measurement procedures ensure clarity, color accuracy, and legibility in diverse driving environments.

Camera Calibration

• Calibration follows guidelines set in IEC TS 63033-1:2017 Annex C.
• Verification involves capturing a 1.5-meter orthogonal frame around the vehicle as a reference within the camera’s image. The frame in composite video must align within a tolerance of 10 cm to ensure spatial accuracy.

Field of View (FOV)

• Defines the visible areas from camera images or composite views.
• Essential FOV zones correspond to regulatory requirements for indirect vision devices and forward driver visibility as per UN regulations.
• Multiple classes of FOV are detailed to cover various perspectives necessary for safe vehicle operation.

Time Behaviour

• Addresses system latency, frame rates, and start-up times to guarantee timely and smooth visual feedback essential for driver situational awareness.

Applications

IEC 63033-3:2019 measurement methods are critical for:

• Automotive manufacturers developing advanced driver-assistance systems (ADAS) and integrated multimedia displays.
• OEM suppliers validating camera modules, image processing units, and monitoring interfaces.
• Regulatory compliance testing labs assessing adherence to international safety regulations related to camera monitor systems.
• Aftermarket device developers ensuring their products meet minimum performance and interoperability standards.
• Enhancing driver safety by verifying system accuracy in representing the vehicle’s surroundings to reduce blind spots and improve maneuvering confidence.
• Supporting ergonomic vehicle design where dynamic viewpoint adjustment improves user experience and reduces cognitive load.

Related Standards

• IEC TS 63033-1:2017 – Provides the foundational system model and general requirements for drive monitoring systems.
• ISO 16505:2019 – Specifies ergonomic and performance requirements and test procedures for camera monitor systems used in road vehicles.
• UN Regulation No. 46 – Covers the approval guidelines for devices providing indirect vision on motor vehicles.
• UN Regulation No. 125 – Defines forward field of vision requirements for motor vehicle drivers to ensure unobstructed views.

By harmonizing with these established standards, IEC 63033-3:2019 ensures that drive monitoring systems deliver measurable, reliable, and safe visual information to drivers, contributing significantly to the advancement of vehicle safety technologies.
