Research Finds ADAS Systems Work With OEM or Aftermarket Windscreens

New research by Autoglass® has found that Original Equipment Equivalent (OEE) glass offers the same top-quality standard as an Original Equipment Manufacturer (OEM) windscreen. The research found that the OEE glass used by Autoglass® does not impact the functionality of Advanced Driver Assistance System (ADAS) sensors.

The research, conducted by TRL, the Transport Research Laboratory, undertook independent tests to compare the performance of ADAS systems calibrated after the installation of OEM and OEE screens. The performance of two ADAS systems (Autonomous Emergency Braking and Lane Departure Warning) were tested under controlled conditions on a test track. After each windscreen change, the ADAS camera was calibrated to the manufacturer’s specification.

The tests concluded that the ADAS technology on a vehicle functions correctly when either OEM or an aftermarket replacement windscreen was used for the repair work. This research does not apply for all aftermarket equivalents.

Dr Chris Davies, Head of Technical Superiority at Autoglass® said: 

“The use of OEM or OEE glass makes no difference to ADAS functionality. This independent research refutes the claim by some manufacturers that their windscreens must be used to ensure the safety technology continues to work properly. This is purely a case of the manufacturers trying to push their own branded products.

“Glass used on vehicles is changing and every year we see more complexity, requiring immaculate quality to house the evolving technology which sits on the windscreen. It is important that the industry is able to adapt and be flexible and our use of OEE glass allows us to offer the best possible service to the customer without any compromise on quality or safety.”

The research in the UK forms part of a global investigation into ADAS calibration and windscreen quality by Belron, the parent of Autoglass®. This conclusion in the UK is supported by the same research from Belron Canada and Safelite® in America, which also tested whether the glass used had any impact on the Automatic Emergency Braking and Lane Departure Warning ADAS functions. The same conclusion was reached across all tests.

Dr Davies added:

“Not all glass is made to the same quality standard, we also know that many VGRRs use inferior glass that doesn’t meet the same rigorous safety standards, and that’s a genuine risk.

“This risk will only increase as the number of cars in the car parc with ADAS technology increases. It is expected that 22% of cars will feature some form of ADAS technology by 2021, so it’s an imperative for the entire industry to ensure that glass used is of the necessary high quality.”
