Proposal to

1. Enable real-time reading of electrical transmission brake values during periodical technical inspections, and
2. Clarify that the Emergency Stop Signal (ESS) may be generated by application of the service braking system via the Electronic Parking Brake (EPB) control.

Proposal to clarify that the Emergency Stop Signal (ESS) may be generated by application of the service braking system via the Electronic Parking Brake (EPB) control.

Proposal to enable the type approval of ADS vehicles, including those without manual controls (to be considered during the June 2026 WP.29 session at the time of consideration of the proposed new regulations on ADS).

Proposal from OICA, CLEPA, and CITA to amend CITA’s proposal to enable real-time reading of electrical transmission brake demand values via an electronic vehicle interface and an off-board electronic device during periodical technical inspections, including a 24-month transitional period.

Proposal to clarify that only one braking control (e.g., service braking control, parking brake control) shall be used for each test condition of the secondary braking effectiveness and to permit the selection of the braking control based on the vehicle load condition.

Proposal to clarify that the Emergency Stop Signal (ESS) may be generated by application of the service braking system via the Electronic Parking Brake (EPB) control.

Proposal from the FADS task force to amend its proposal to enable the application of UN R13-H to ADS vehicles.

Proposal to enable real-time reading of electrical transmission brake values during periodical technical inspections.

Proposal from the FADS informal group to introduce amendments to enable the type approval of ADS vehicles, including those without manual controls.

The Task Force on regulatory Fitness for Automated Driving Systems reports proposed amendments to UN R13, R13-H, and R79. Amendments to R13 and R13-H, submitted as GRVA/2025/24 and GRVA/2025/25, include general clarifications, relaxed manual control requirements for vehicles of categories X and Y, clarification of braking system warning transmission to the ADS, and ESC compatibility provisions. R79 amendments, submitted as GRVA/2025/23, establish baseline manual control requirements for X and Y vehicles, remote control capabilities, ADS steering equipment requirements, and remove ALKS exemptions. Transitional provisions apply. The task force coordinates with other expert groups on horizontal topics and continues amending additional UN Regulations.

Proposal to clarify that an Emergency Stop Signal may be generated by application of the service braking system via the Electronic Parking Brake.

Proposal to enable the type-approval of ADS vehicles, including those without manual controls.

Proposal to amend provisions in documents GRVA/2025/13 and GRVA/2025/14 concerning the type approval of a park lock device as an alternative to or in combination with the friction parking braking.
