Proposal to amend Annex 8, para. 3.4.1. to require the manufacturer’s statement and explanation to address how the chosen strategy will not prejudice safe operation of systems involved in achieving the function of the system, such as tyres or wheels, and to require the Technical Service to assess the explanation and validation plan, and amend Annex 8, para. 3.4.4. to require documentation to include analysis of faults with other systems involved in achieving the function of the system and to require the Technical Service assessment to include inspection of the safety approach at vehicle level with confirmation of consideration of interactions with other vehicle systems. The proposal responds to a fatal collision where a tyre failure combined with ABS activation resulted in unsafe braking performance. Expanding the functional safety assessment beyond the braking system to include all relevant systems ensures all faults influencing system function are captured.

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.
