The CS/OTA Task Force held its thirty-seventh session on 21-22 April 2026 by video conference. The group adopted the provisional agenda and minutes from the thirty-sixth session. Discussions addressed proposals for amendments to UN R155 concerning multi-stage vehicle approvals and separate technical units, for which a subworking group was established. Proposals were also considered on type approval authority responsibility for cyber security management systems and remote operation of automated driving systems. The group reviewed cyber and software requirements in the ADS GTR and WP.29/2022/60 as amended by WP.29/2023/87, and discussed application of RXSWIN to UN Regulations, selecting option 2 for presentation to GRVA with R155, R156, and R89 square bracketed. The IWG mandate renewal was discussed, with potential new items including component and STU approval and software numbering proposals.

Proposal to insert provisions on software identification and software updates into UN R13, UN R13-H, UN R79, UN R89, UN R130, UN R131, UN R152, UN R155, UN R156, UN R157, UN R171, UN R175, and UN R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles, clarifying that production discontinuation does not apply when manufacturers seek approval extensions for software updates of registered vehicles, and amending communication forms to include software identification numbers and related information.

Proposal to amend UN R13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178 by introducing provisions on software identification and software updates. Amendments add new paragraphs referring to Software Identification Number definitions in Consolidated Resolution R.E.3, require manufacturers to provide Technical Services with information on hardware and software influencing performance, permit vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles while avoiding test duplication, and modify production discontinuation provisions to exclude cases where manufacturers seek approval extensions for software updates of registered vehicles.

Proposal to introduce references to ADS acceleration demands, establish speed limitation requirements for vehicles of Categories X and Y, require ASLF and ASLD deactivation upon ADS feature activation, and specify testing procedures including dedicated activation methods for vehicles without manual driving controls.

Proposal to remove the draft provisions concerning the approval of stability performance under UN R13 and UN R140 for ADS vehicles via demonstration under the safety case provisions of the forthcoming UN Regulation on ADS, and to remove bracket unintentionally retained in the original submission.

Proposal to clarify the references to UN R10 in UN R89. This was part of a collective amendment proposal concerning (in addition to UN R89) UN R13, UN R13-H, UN R79; UN R130 and UN R131. Proposal also to

1. exempt cases where the driver has temporarily deactivated the speed limiter from the warning requirement for excess speed in in order to reduce driver distraction
2. introduce throttle control via adjustment of the accelerator pedal position
3. to correct an editorial error in paras. 5.2.5.4.2. and 21.2.5.4.2.

The European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) requires vehicles to be equipped with a speed limitation device compliant with UN R89. UN R89 refers to speed limitation devices (SLD) and speed limitation functions (SLR) (i.e., aims to be technologically neutral). Russia requests GRRF confirmation that compliance with UN R89 can be achieved through either an SLD or SLF.

Revised proposal from OICA pursuant to comments received during the previous GRRF session to

1. exempt cases where the driver has temporarily deactivated the speed limiter from the warning requirement for excess speed in in order to reduce driver distraction
2. introduce throttle control via adjustment of the accelerator pedal position
3. to correct an editorial error in paras. 5.2.5.4.2. and 21.2.5.4.2.

Presentation of issues raised during discussions of the GRE Task Force on EMC requirements with regard to the application of several UN Regulations to trolley buses depending upon their configuration (e.g., dual-mode operation either connected to overhead cables or in standard bus mode).

Proposal to extend the possibility of actuating the service braking system to vehicles of categories M2 and N2 below 5t.

Proposal to extend the possibility of actuating the service braking system to vehicles of categories M2 and N2 below 5t.

Reference prepared by the WP.29 secretariat

Proposal for collective amendments of amendments to Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices) and the new Regulations on LDWS and AEBS to clarify the references to Regulation No. 10 into the UN Regulations mentioned above.

Italy proposes to introduce into each Regulation dealing with the type approval of lighting or light signalling devices a direct reference to the requirements contained in Regulations 48, 53 and 74, and 86, mandating the lamp manufacturers to apply them to obtain type approvals.

Several vehicle control regulations refer to compliance with UN Regulation No. 10 on electromagnetic compatibility. The proposal would revise these references to focus only on the technical (thus excluding administrative) requirements since some countries do not apply UN R10.
