  1. DG eCall meetingBrusselsEG.2 17 November 2005

  2. EG. 2 members • Lennart Strandberg, Autoliv • Magnus Haraldsson, Autoliv • Alfred Krappel, Motorola • Gianmaria Timossi, Magneti Marelli • Olivier Beaujard, Wavecom • Darren Stratton, SonyEricsson • Stefan Gudmundsson, SonyEricsson • Stephane Pellerin, Sagem • Andreas Kohn, Siemens

  3. Objectives/Description • Objectives • Define the high level functional requirements for a in-vehicle system and a nomadic devise as the eCall generator • Description • Fact finder study on requirements for the In-Vehicle System and a nomadic device based on the results from “PSAP.1”

  4. EG.2 Working Principles The approach for establish the EG.2 Clarification Paper has been that all EG.2 members has been asked to give input to the paper, Autoliv has then compiled the inputs into the document. The work has been done via e-mail and telephones conferences, no face to face work shop has taken place.

  5. Block Diagram

  6. Functions IVS * The cost for a nomadic device with GPS (smart phone) will be an added cost for the customer ** The nomadic device needs to be charged *** SIM or no SIM discussions

  7. Pros & Cons Embedded vs Nomadic

  8. Nomadic device

  9. Embedded device

  10. Pros & Cons SIM vs No SIM

  11. Pros & Cons With SIM

  12. Pros & Cons Without SIM

  13. SIM issues • Is it eCall requirement to make a call-back to the car if the connection is interrupted, this is not possible without a SIM? • How will we handle identification on pre-paied cards, if the buyer is anonymous? • How can we act so that all operators allow 112 calls without SIM?

  14. Localization accuracy • Is accuracy a real issue? • GPS accuracy 10 m is enough

  15. Vehicle Interfaces • ACU interface • Physical Interface: • This will most probably not be standardized, it will be different from one manufacturer to another depending on vehicle architecture. • Triggers and Thresholds • More studies need to be done • Interface Manual Trigger • Requirement: there should be a manual triggerThe implementation will differ from one car manufacturer to another depending on vehicle architecture • Audio interface • Requirement: there should be a eCALL speaker and microphoneThe implementation will differ from one manufacturer to another depending on vehicle architecture

  16. Automotive requirement • The in vehicle system must fulfill the automotive requirements: • Operating temperature rage (-40°C to +85°C) • EMC compatibility • Reliability • Resistance to shock, vibrations, corrosion, water

  17. Transport Protocol/Bearer • The work is ongoing within ETSI • Protocol candidates • GTP (Global Telematic Protocol) • GSM Signalling protocol • Data bearer candidates • USSD (Unstructured Supplementary Service Data) • UUS.1 (User to User signalling) • SMS (Short Message Service) • Airbiquity (digital modem over voice channel) • DTMF (Dual Tone Multiple Frequency)

  18. Cost estimation • The cost estimation does not include costs for microphone, speaker, MMI (manual trigger), external antennas. • Embedded device cost for automatic E-Call will be <100 Euros in 2009. This cost is related to a crash-proof solution able to perform the following functions: • Positioning (GPS + dead reckoning) • Communication protocol management (SMS or data, Voice) • Airbag signal management • Power supply management, with integrated backup battery • Cost for the In vehicle part of a Nomdic system is approximately 50% of a embedded system, cost for smartpohone not included

  19. Open key issues • SIM, no SIM • Transport Protocol/Bearer specification (ETSI) • E-CALL trigger requirements • MSD (what data is mandatory)
