Comments on the draft amendment to UN R79 addressing automated steering as it stood at the end of the third ACSF informal group session. This document also raises links to rear vision (UN R46), AEBS (UN R131), and park assist systems.

Working draft pursuant to the 10th AECS informal group session (September 2015).

Updated version of the text following the 11th R55 informal group session and highlighting the changes

Updated version of the draft consolidated revision of UN R55 following the 11th R55 informal group session.

Draft proposal under development within the R55 informal group.

Proposal under preparation for the GRRF by the R55 informal group. This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. This proposal would amend the Revision 2 proposal for UN R55.

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

Comparison of the 227g ball impact test across UN R43, Japan “Safety Regulations for Road Vehicles, Article 29”, US FMVSS 205-ANSI/SAE Z26.1-1996, and GTR No. 6.

Description of an accident wherein a blind person was killed by a truck backing up with its reverse-mode sound signal deactivated and of possible policy responses in Japan.

UN R55 does not include provisions for minimum articulation angles of couplings. However, couplings may be damaged if a vehicle combination takes a narrow curve or other maneuver that exceeds the coupling design. In order to prevent coupling failures, this proposal suggests minimum articulation requirements based partly upon ISO 1726-1 and 11407 for drawbar and fifth wheel couplings.
