Informal Group on Accident Emergency Call Systems | Session 3 | 26-28 Feb 2014
Moscow
Agenda Item 5.2.
Technical items

EMC
Background:

  • simply referring to UN R10, or including all necessary requirements into the regulation
  • not all UN R10 requirements are necessary for AECD/AECS
Status of discussions at GRSG-AECS informal group: reference to UN R10, plus additional relevant tests if necessary.

Climate resistance
Background:

  • Need to ensure proper resistance to climate extremes in order to guarantee emission of e-call in all circumstances. Item of particular importance in RUS
  • Resistance to climate usually not defined in other regulations, except UN R97, R116 and few others. Industry and J consider this as “over-regulation”.
  • Resistance to climate currently well addressed by the market in the frame of product liability.
Status of discussions at GRSG-AECS informal group: item to be further discussed with proper justifications

Mechanical resistance
Background:

  • Need to ensure proper resistance to mechanical aggressions in order to guarantee emission of e-call in all circumstances
  • OICA concerned that the proposed requirements could be detrimental to safety as the manufacturers usually adapt the specifications to the vehicle.
Status of discussions at GRSG-AECS informal group: item to be further discussed with proper justifications.

AECS triggering conditions (UN R94/R95 environment)
Background:

  • Question on whether UN R94/95 are relevant for assessing AECD/AECS resistance to crash
    • Worst case configuration
    • AECD/AECS post-crash functionality assessment
  • Proposal to perform a separate AECD sled test
  • Status of discussions at GRSG-AECS informal group:
    • Verification (in minimum) of generation of trigger signal during the UN R94/95 impacts,
    • audio capabilities and MSD transmission during crash test procedure.
  • This can also be done via other measures.

Navigation module requirements
Background:

  • Question on whether the regulation should mandate GNSS for achieving accuracy in positioning (design restriction vs. technical necessity)
  • European Commission keen that all AECD/AECS are Galileo compatible
Status of discussions at GRSG-AECS informal group: general requirements with no technology, and approval tests imposing GNSS.
