Automakers can now achieve compliance for their drowsiness monitoring system using JDS as the ground truth

Automotive Original Equipment Manufacturers (OEMs) can now achieve both EU General Safety Regulation (GSR) compliance and European New Car Assessment Programme (Euro NCAP) assessment using Optalert’s non-invasive Johns Drowsiness Scale (JDS™) as the ground truth.

Numerous automotive technical services firms in Europe, including UTAC, TÜV Rheinland, and Applus+ IDIADA, have reviewed the evidence and confirmed that Optalert’s JDS is a compliant measure of drowsiness under the European GSR. All of them operate Euro NCAP accredited testing laboratories. Each of them has recognised Optalert’s JDS as a valid alternative to the KSS[1]. This will ensure compliance with the latest European regulations and future-proof design for both Euro NCAP assessment and the anticipated stricter requirements of the 2024 European regulations.

“This recognition has been made after a thorough review of the large volume of independent scientific evidence provided by your organisation, demonstrating the effectiveness and reliability of your drowsiness detection technology,” acknowledged UTAC’s Head of Technical Expertise and Vehicle Regulation Department, Céline Vallaude.

Optalert’s objective JDS™ is non-invasive and passively detects the driver’s impairment from drowsiness via their eyelid movements. It is the most accurate measure of its kind, bringing to the automotive market the most state of the art science and research available in drowsiness monitoring. Until now, the primary ground truth for testing drowsiness monitoring systems was the Karolinska Sleepiness Scale (KSS). This involved training the driver and asking them how tired they were every five minutes, inadvertently rousing them and invalidating the test. OEMs have been surprised and frustrated when their systems performed drastically differently once moving from test conditions to real world driving. Optalert’s JDS™ will minimise these frustrations, making the transition seamless.

This clears the way for both OEMs and tier 1 suppliers to either integrate Optalert’s drowsiness measurement technology via a software development kit (SDK) into their driver monitoring system (DMS) or occupant monitoring system (OMS), or validate their own drowsiness detection technology using Optalert’s JDS™, a scientifically validated objective measure of drowsiness.

It is heartening to see the industry moving away from the imprecise and subjective KSS to the more accurate, reliable, and objective JDS™. The JDS™ is a superior neurological biomarker that directly quantifies impairment from drowsiness. It requires no driver interaction, ensuring it does not bias the measurement.
