Adaptive Front Lighting System (AFLS)


Technology

  • Adaptive Front Lighting System (AFLS) suitable for Indian Road and traffic conditions
  • TRL-6 (Prototype with Validation and Validation)

Illustration of AFLS modes: Country, Town, Expressway, and Dynamic Swivel

Properties/Features

  • Provides wider visibility in town and country roads during night driving
  • Provides longer range of visibility at higher speeds especially on expressways.
  • Avoids exposure glare on oncoming passengers as the system encourages use of Low Beam
  • Automatically selects the required light pattern from pre-defined set of modes
  • Automatically aims light according to the passenger occupancy
  • Swivels to follow road and traffic conditions
  • Cost effective indigenous solution

Application

  • Applicable for Advance Lighting technologies in passenger and commercial vehicle segment
  • Applicable for both projector and reflector based headlamps
  • Applicable for 2W/3W/4W/Bus and Construction & Mining equipment vehicles can also be developed

Scale of Validation Achieved

The AFLS equipped vehicle was driven through various test geometries and traffic conditions including Ghat section for verification of Dynamic Swivel, and on expressway for high speed related aiming. Calibration and verification of the system was carried out on test tracks and proving ground. The system and its functionalities have been evaluated as per standards AIS-008 and AIS-127, equivalent to ECE-R112 and ECE-R123 respectively.

Abstract

The Automotive Research Association India has developed indigenous and cost effective technology solution for Adaptive Frontal Lighting System (AFLS) for passenger cars and SUVs/MPV. This algorithm is designed to address needs of Indian road and traffic conditions. AFLS adjusts the headlamp beam pattern to driving condition, environment, further vehicle. The AFLS operates in different modes, viz. Expressway Mode, Country Mode and Town Mode. The developed prototype AFLS ECU has been integrated with a UDS enabled Electrical & Electronic Architecture on CAN network to achieve these modes. These AFLS modes are achieved using actuators by controlling beam pattern of projector headlamps as well as ON/OFF of cornering lamps and vehicle parameter signals from the car. Speed thresholds are optimized to meet the Indian traffic requirement. With this AFLS technology development, ARAI is now able to offer the following development services in automotive lighting.

Functional Architecture Development:

  • Component selection for intelligent Lighting Technologies
  • Software development using MATLAB & Simulink / C
  • Verification and validation methodologies
  • Consultancy for AFLS development and new technologies in the area of lighting

ARAI is also geared-up to develop similar AFLS technologies for 2&3 wheel vehicles, Buses, Commercial Vehicles, off-road vehicles and Construction & Mining machinery vehicles as well.

Beneficiary Industry

  • Vehicle Manufacturers of 2w, 3w, Cars, SUV/MPV, Buses, Commercial vehicles etc…
  • Lighting Systems Manufacturers supplying to vehicle OEMs.
  • Off road vehicles manufacturers/integrators working on Mining equipment & vehicles
