Standards for Adaptive Front-lighting Systems (AFS) on vehicles

ECE R123 is a European standard that provides guidelines for the approval of adaptive headlights, also known as Adaptive Front-lighting Systems (AFS). These advanced headlights automatically adjust to driving conditions such as speed, weather, and curves. This improves visibility and enhances the safety of both the driver and other road users.

What does the regulation describe?

ECE R123 specifies the technical requirements for the approval of adaptive headlights on vehicles. The standard focuses on aspects such as light intensity, light distribution, and the functionality of the adaptive system. The aim is to ensure that the headlights effectively adapt to different driving conditions without dazzling other road users.

Key requirements of ECE R123

The regulations include guidelines for various technical aspects of adaptive headlights:

  • Light Intensity: The standard specifies different classes of light beams that adjust to specific driving conditions, such as Class C (city traffic), Class V (highway), Class E (extra lighting), and Class W (cornering lights). Each class has specific technical requirements for light intensity and distribution, depending on the driving environment. This ensures that adaptive headlights perform optimally under various conditions without dazzling other road users.
  • Adaptive Functionality: The system must automatically respond to changing conditions, such as the vehicle's speed or the steering angle. This ensures that the lighting is adjusted to optimize the driver's visibility.
  • Adaptieve functionaliteit: Het systeem moet automatisch reageren op veranderende omstandigheden, zoals de snelheid van het voertuig of de hoek van het stuur. Hierdoor wordt de verlichting aangepast om het zicht van de bestuurder te optimaliseren.

Related topics: This standard is often linked with ECE R48, which focuses on the installation and use of lighting on vehicles. Also relevant is ECE R10, which deals with the electromagnetic compatibility of vehicles.

Frequently Asked Questions about ECE R123

What is the difference between ECE R123 and other headlight standards?

ECE R123 focuses specifically on adaptive headlights, while other standards like ECE R112 are aimed at standard headlights. ECE R123 provides targeted guidelines for the unique characteristics and functionalities of adaptive lighting, which adjusts to various driving conditions.

Why are adaptive headlights important for road safety?

Adaptieve koplampen verbeteren de zichtbaarheid van de weg door zich automatisch aan te passen aan de rijomstandigheden. Dit helpt de bestuurder om obstakels en andere weggebruikers beter op te merken, wat de kans op ongevallen verkleint.
