Proposal to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.

Proposal to

1. delete redundant provisions (paragraphs 2.2. and 2.2.1.) in favor of paragraph 5.2.2.13. which requires all O4 trailers to be equipped with Anti-lock Braking Systems (ABS) of Category A.
2. clarify exemptions from electronic stability control requirements, and
3. enable the verification of sufficient movement of the balancer without having to take measurements underneath the trailer.

Proposal to expand the scope of UN R90 to include requirements for the approval of replacement brake lining assemblies for L-category vehicles.

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF). This proposal includes amendments the annex on complex electronic systems (Annex 6), in particular, to require auditing of the methodologies used to ensure system safety at both concept and system level. The concept level specifically requires consideration of interaction with other vehicle systems.
