This informal document proposes amendments to UN R78 to introduce new requirements for “Complex Electronic Control Systems” aimed at addressing new technologies such as automatically commanded braking.

Comments on the proposal for amendments to the UN Regulation on Cyber Security Management.

Proposal to introduce requirements to enable the type approval of Electro-Mechanical Braking (EMB) systems.

Proposal to introduce provisions for electric regenerative braking systems.

Revised version of the FRAV recommendations as updated pursuant to GRVA discussions.

Revised text based on document WP.29-187-08 submitted by the VMAD informal group.

Proposal to correct an error in para. 2.3. Weight reduction solutions for brake discs must yield a higher (not lower) ratio between vehicle kinetic energy and mass of the disc braking surface than the reference disc.

Proposal to introduce new text concerning activation: “Notwithstanding the activation criteria above and following the activation request at any type of road by a deliberate action with the same means as for ACSF of Category B1, the ACSF of Category C may turn automatically to standby mode when entering a type of road as described above.”

Proposal for a provision to address use of a steering robot with mechanical power greater than 1200 W to enable testing of certain direct (low) steering gear ratio systems due to the given 0.7 Hz sine frequency.

Proposal to clarify the interpretation of “engine start/run cycle”.

At the 13th session of GRVA the UK presented an informal document (GRVA-13-19) with the purpose of starting discussion on the content of UN Regulation 13, Annex 18. The proposal was made in recognition of the inconsistent understanding of the current text, identified during the discussions leading to the 03 series of amendments to UN R79 which shared common language. It is intended that using harmonised text between Regulations, as far as is practicable, will deliver more consistent application of the requirements and avoid unnecessary changes in procedures and documentation for different vehicle systems.

Review of the existing national / regional activities and a proposed way forward for DSSAD.

Input concerning the review of existing UN Regulations and Global Technical Regulations with regard to their application to vehicles equipped with Automated Driving Systems.

Updated proposal from the UN R157 special interest group to revise provisions concerning DSSAD and data recording/storage.
