Virtual Headlight Leveling Sensor on Sonatus AI Director
Unlocking In-Vehicle AI for Smarter Headlight Leveling — A comprehensive case study demonstrating how COMPREDICT's AI-driven Virtual Sensor technology revolutionizes automotive safety while reducing costs.
COMPREDICT, in partnership with Sonatus, has developed an AI-based Virtual Headlight Leveling Sensor to meet the 2027 UN R48-09 regulation, replacing costly traditional sensors. This software-only solution utilizes CAN signals and the Sonatus AI Director platform to deliver accurate, real-time headlight leveling across various vehicle platforms, reducing hardware costs by up to $20 per vehicle.
The Challenge
To meet the UN R48-09 regulation requiring automatic headlight leveling in European passenger vehicles by 2027, automakers have traditionally relied on expensive hardware ride height sensors. These physical sensors add significant costs to the bill of materials while limiting flexibility in vehicle design and architecture.
COMPREDICT recognized the opportunity to replace these hardware sensors with a 100% software-based Virtual Sensor using AI technology. The challenge was to create a solution that could accurately calculate vehicle pitch angles using existing CAN signals while ensuring regulatory compliance and seamless integration across different vehicle platforms.
The Solution
COMPREDICT's Virtual Headlight Leveling Sensor leverages existing CAN signals, made available via Sonatus AI Director, to calculate the current pitch angle of the vehicle. After processing by the COMPREDICT model, the pitch angle is made available to other consumers on the vehicle network to control the headlight actuators.
