Proposal to increase yaw rate recording frequency to 10 Hz. Yaw-rate data recorded at 2 Hz corresponds to one measurement every 500 ms; increasing to 10 Hz provides a measurement every 100 ms, resulting in a fivefold improvement in temporal resolution. This enhancement significantly improves ability to reconstruct pre-crash vehicle dynamics, identify vehicle instability onset and progression, and evaluate Electronic Stability Control functionality. A yaw-rate recording frequency of at least 10 Hz reduces temporal uncertainty from 500 ms to 100 ms and enables more accurate reconstruction of loss-of-control events, vehicle rotation, ESC interventions, and driving dynamical issues.
International reference standards for harmonics and flicker testing define differing applicable supply voltage levels and operating frequencies. CLEPA proposes maintaining baseline requirements for UN R10.08 unchanged, testing according to standardized parameters of reference IEC standards. Contracting Parties with diverging local grid configurations should define tailored national requirements or propose harmonized evaluation methods directly within relevant IEC standard committees, as direct application or mathematical conversion of limits for diverging grids lacks standardized metrological foundation in IEC publications.
Document raises question on the use of a combination of Level I/II immunity tests based on ISO 7637-2:2011 in the 07 series given that the 06 series prescribed Level III.
The document addresses open issues and comments regarding UN R11 and GTR No. 1 concerning emergency door opening. It proposes defining vehicle master control switch as the device bringing onboard electronics from off to normal operation mode, and suggests activating this switch rather than switching ignition on in test procedures. The document defines main power supply as power source(s) and supply path(s) normally used for door system operation, excluding secondary or back-up supply. It raises concerns about secondary or back-up power supply failure occurring in the field before emergencies despite compliant test results. The document discusses objective intuitiveness criteria including visibility, accessibility, discoverability, identification, and operability. It recommends standardized marking for exterior door handles and proposes that door opening and closing procedures be described in vehicle owners’ manuals.
Proposal to insert a new definition of functional test configuration, amend para. 2.1.1.2. to clarify that test conditions are agreed between manufacturer and technical service and that tables provide guidance which may be extended or amended depending on vehicle characteristics, add tables specifying basic vehicle test conditions for “50 km/h mode,” “Brake mode,” and “Active ADS Mode,” add an alternative “Brake mode” with active ADS for vehicles where braking mode cannot be applied with ADS operational without ADS feature(s) activated, add AECS and AVAS test condition tables, and insert a new table cross-referencing UN Regulations with specific provisions and test configurations to demonstrate compliance with UN R10.
Proposal to require test reports provided by manufacturers to comply with paragraph 3.3. and to be attached to the test report of the technical service.
Proposal for conducting the ADS Active Test Specified in Annex 6 to clarify ADS Active Mode, clarify methods to activate ADS using test equipment or by modifying in-vehicle ADS-related ECU software, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, including testing in a non-active state using warning indicators and diagnostic functions, and testing when errors occur upon ADS activation. The proposal defines ADS Active Mode as representative ADS functions remaining operational using sensors whose inputs can be simulated within the anechoic chamber environment, with alternative test methods including application based on ESA or subsystem test results, testing with ADS not activated using steady-state driving conditions with pass/fail criteria verifying no communication errors, ECU malfunction, freeze, shutdown, or ADS system malfunctions occur, and testing with simulated sensor outputs using data from real-world driving or representative driving scenarios.
