NEW UN REGULATION PAVES THE WAY FOR THE ROLL-OUT OF ADDITIONAL DRIVER ASSISTANCE SYSTEMS UNVEILS SMART SEAT BELT TECHNOLOGY
UNECE’s Working Party on Automated/Autonomous and Connected Vehicles has adopted the draft of a new regulation that defines provisions for the approval of vehicles with Driver Control Assistance Systems (DCAS) and provides minimum safety requirements for vehicles equipped with the Advanced Driver Assistance System (ADAS), such as lane keep assist.?
DCAS are a subset of Advanced Driver Assistance Systems (ADAS). While active, DCAS are able to stabilize or manoeuvre the vehicle. ?
The new regulation builds on?UN Regulation No. 79?adopted in 2018 and covers a broader range of technologies to be introduced in new models. For instance, the new regulation will no longer limit the use of lane changing systems to motorways (roads with 2 lanes and a physical separation from traffic in the opposite direction) but will extend it to other types of roads. ?
The new regulation aims to allow the approval of a combination of driving control assistance features, including assistance to braking, accelerating, and overtaking. ?
However, the new regulation does not cover full driving automation, and therefore requires manufacturers to implement strategies to ensure that drivers have appropriate knowledge of the capabilities of assistance systems and do not overestimate them (mode awareness).?
To avoid driver overreliance on such systems, the regulation stipulates that DCAS shall be designed to ensure that the driver remains engaged with the driving task. The driver’s hands must remain on the wheel and the system shall monitor the driver’s visual engagement with the road, triggering alarms after 5 seconds when it detects that this is no longer the case.?
The regulation also stipulates that manufacturers will be required to submit an outline of the systems’ design to type approval authorities. The validation of DCAS shall ensure that a thorough assessment, considering the functional and operational safety of the features integrated in DCAS and the entire DCAS integrated into a vehicle, is performed by the manufacturer during the design and development processes. ?
The regulation will require manufacturers to monitor the performance of these systems once on the roads and provide periodic (at least once a year) and ad-hoc reports on critical safety occurrences to the authority that approved the vehicle.?
The new regulation will be submitted to the World Forum for Harmonization of Vehicle Regulations (WP.29) for adoption in June 2024, with an entry into force foreseen in January 2025.

DRI LAUNCHES NEW ADAPTIVE DRIVING BEAM TESTING SERVICE FOR US MARKET
领英推荐
Dynamic Research Inc (DRI), a leading test consultancy, has developed new testing capabilities for Adaptive Driving Beams (ADB) as the latest legislation from the National Highway Traffic Safety Administration (NHTSA) allows the technology to be used in the US market for the first time.
A study by the Insurance Institute for Highway Safety (IIHS) found that pedestrian deaths increased by 56% in dark conditions between 2009 to 2016 and cites better headlights as a solution to this problem [1]. ADB enables the vehicle’s high beams to be used continuously as the system automatically adjusts the direction and intensity of the light beam to prevent glare for surrounding traffic. This improves visibility for the driver and better illuminates Vulnerable Road Users (VRU), such as pedestrians.
While these headlights are prevalent in other markets, pre-existing legislation in the US didn’t accommodate their use. As a result, NHTSA revised its FMVSS 108 headlight standard to enable vehicles in the US to be equipped with ADB technology. This has been accompanied by a new test procedure to evaluate the performance of these headlights.
"OEMs that have invested in ADB technology will be keen to exploit it in the US market and we have already seen a significant increase in demand for ADB testing in the region," said Nadine Wong, DRI Director of Track Testing. "The combination of our bespoke test equipment and the smooth paving on our proving ground, which is critical to ADB testing, means we are perfectly placed to help OEMs and Tier 1 suppliers ensure they are ready to meet these latest regulations."
DRI has introduced new test capabilities, including in-house designed lighting and sensor rigs, to conduct the dynamic test procedure at its Minter test facility in California. The vehicle under test is precisely driven through a series of turn radii and speeds using AB Dynamics driving robots while the lighting rig mimics surrounding vehicle headlights and taillights. The rig is also equipped with luminance sensors positioned to represent where the driver would be with the resulting lux measurements showing how effectively the ADB technology is adjusting its beam to reduce glare. The company has also developed post-processor software to evaluate if the vehicle successfully passes the test, providing an end-to-end test solution.
The California test facility is sufficiently large to accommodate the various driving paths dictated by this latest standard. The track also features high-quality surface grade pavement, which is essential for ADB testing as it minimizes the variation in vehicle pitch caused by bumps, improving the consistency of results.
DRI offers comprehensive testing and validation services for adaptive headlight systems and the company has already successfully completed the latest test protocols for European and Japanese OEMs.
"DRI has a close working relationship with NHTSA as an approved contractor for ADAS verification testing and often supports the creation and improvements of new protocols," continues Wong. "As an independent consultancy, OEMs can work with DRI to not only test and develop their ADB systems but also generate the necessary data to self-certify for the updated legislation."
