European Commission draft regulatory language for its Regulation on Vehicle Construction Requirements (RVCR) and UN R100 for L-category electric vehicles.

“COMMISSION DELEGATED REGULATION (EU) No …/.. of XXX supplementing Regulation (EU) No 168/2013 of the European Parliament and of the Council and amending Part A of its Annex V with regard to the environmental and propulsion performance requirements for two- or three-wheel vehicles and quadricycles”

The EU established Regulation (EU) No 540/2014 concerning vehicle noise in 2014. This regulation includes provisions for acoustic vehicle alerting systems (AVAS) in Annex VIII. This document summarizes Commission objectives and plans with regard to the draft UN Regulation on this same subject.

Proposal to ensure that EDR record collisions involving vulnerable road users.

Proposal to amend Annex 4 – Data elements and format, Table 1, modifying Advanced driver distraction warning (ADDW) data elements to record status and time since warning issued instead of number of warnings and time elapsed since last warning, modifying Driver control assistance system (DCAS) driver monitoring system data elements to record time since disengagement warning issued and warning type instead of number of hands-on requests, eyes-on requests, direct control alerts, and time elapsed since last warning, and adding Driver drowsiness and attention warning (DDAW) status and time since warning issued data elements while removing number of warnings and time elapsed since last warning, with ADDW and DDAW elements listed up to five times for most recent warnings and DCAS warning type listed up to fifteen times for most recent warnings on current trip.

Proposal to add retrieval of DSSAD time-stamp data elements recorded for at least the last 30 seconds before the last setting of the event flag “Event Data Recorder (EDR) trigger input” alongside EDR data through the same interface, add provisions for retrieval when no such event occurs within the last 30 seconds, add provisions to replace date and time with relative time information when required by national or regional law, and add detected collision by Automated Driving System as an EDR trigger for UN R160 and UN R169.

Proposal to amend UN R160:

• Amend definitions 2.8., 2.10., and 2.11. to clarify that automatically commanded steering function categories B2, D, and E are not part of a DCAS
• Delete definition 2.25.
• Amend definition 2.35. to simplify non-volatile memory
• Amend para. 2.45. to change service brake terminology
• Amend para. 2.51. to clarify time interval between events
• Amend para. 2.65. to abbreviate vulnerable road user
• Insert new definitions 2.71.–2.83. for rollover protection system, advanced emergency braking system, trigger activated, pre-event synchronization timer, blind spot monitoring system, emergency stop signal, turn signal, acceleration control for pedal error, advanced driver distraction warning system, driver drowsiness and attention warning system, driver control assistance system, and time to collision
• Restructure para. 5.3.1. to distinguish planar, VRU, and rollover events from AEBS events with specified triggers
• Amend para. 5.3.2. to clarify data locking conditions
• Restructure para. 5.3.3. to establish time zero for planar, VRU, rollover, and AEBS events
• Amend para. 5.4.3. to specify side and frontal collision tests
• Amend para. 6.1. to clarify post-crash acceleration measurement
• Insert transitional provisions 12.12.–12.16. providing that as from the official date of entry into force Contracting Parties shall not refuse type-approvals under the 03 series, as from 1 September 2031 or 2029 [date TBD] shall not accept type-approvals to preceding series first issued after that date, until 1 September 2033 shall continue accepting preceding series approvals first issued before 1 September 2031 or 2029 [date TBD], may grant approvals to preceding series, and shall grant extensions of existing approvals
• Amend Annex 4 Table 1 to split engine throttle and accelerator pedal data elements, increase sampling rates to 10 Hz, extend recording intervals for rollover events, add pre-event synchronization timer, trigger activated, ACPE status, ADDW status, DDAW status, blind spot monitoring status, turn signal status, DCAS status, DCAS driver monitoring system warnings, emergency stop signal status, and time to collision data elements, and modify footnotes accordingly

Proposal based on GRSG/2026/38 to amend para. 2.18. to define end of event time separately for planar events and all other events, amend para. 2.20. to redefine engine throttle percent full, insert new definitions for Advanced emergency braking system (AEBS) and Trigger activated, amend para. 5.4.3. to modify crash test data requirements and reference UN Regulations Nos. 95 and either 94 or 137, and amend Table 1 in Annex 4 to modify data element requirements including changing Air bag warning lamp and other elements from conditional to Mandatory, adding AEBS event recording, modifying Yaw Rate recording intervals and sample rate, clarifying Vulnerable road user secondary safety system warning indicator status recording, modifying Accident emergency call system status recording interval, and revising footnotes regarding TTC calculation and AEBS requirements, effective upon entry into force of the 03 Series of Amendments.

European Commission priorities for EDR Step 3 include improving detection of vehicle-to-vulnerable road user collisions and low-severity vehicle-to-vehicle collisions through adjusting delta-v trigger thresholds, developing new jerk-based trigger criteria, and exploring ADS collision detection for EDR triggering in automated vehicles on a long-term timeline. Data elements and format must be ensured to remain up-to-date with new safety system developments and close gaps between light and heavy vehicles through reviewing data elements in light of newly regulated safety systems and mirroring DDAW, ADDW and DCAS data elements from UN R160 to UN R169 on short-term and ongoing timelines.

Proposal to clarify that the EDR volatile memory buffer for last stop trigger activation shall accommodate data related to at least five different stops to be overwritten on a first-in first-out basis, and that data for the most recent stops shall be written to non-volatile memory in a way that does not interfere with the event record related to any other trigger of paragraph 5.3.1.

For vehicles equipped with an Automated Driving System, it shall be possible to retrieve DSSAD time-stamp data elements specified under paragraph 5.2. of Annex 8 of UN Regulation No. 185 recorded within at least the last 30 seconds prior to triggering of the respective EDR event, regardless of whether the DSSAD and the EDR are implemented as a single system or as separate systems. The time-stamp data elements retrievable from the DSSAD shall include the record for the last activation or deactivation of the feature used at the time of the event within the same power cycle. The data elements shall be retrievable in the format specified in Annex 8 of UN Regulation No. 185, though DSSAD location data may be omitted and dates and times recorded may be replaced with information representing the time elapsed between the recording of each DSSAD data element and the triggering of the EDR.
