2.23. "AECD (Accident Emergency Call Device)" means a unit or a set of components performing at least the following functions: (a) Receiving and/or generating the automatic and manual triggering signals; and (b) Sending a Minimum Set of Data (MSD). It may in addition perform any of the following functions: (a) Receiving or determining the vehicle location; (b) Providing a warning signal; and (c) Allowing bidirectional audio signals for voice communication, unless specified otherwise in this Regulation. 2.24. "AECS (Accident Emergency Call System)" an AECD when installed in a vehicle. 2.25. "Triggering signal" means a logic signal that requests emergency call transaction. 2.26. "Minimum Set of Data (MSD)" means a set of data as defined in Annex 12. 2.27. "Control module" means a component designed to ensure the combined functioning of all components of the AECC/AECD/AECS. 2.28. "Information signal device" means a device that provides information on the status of the emergency call transaction. 2.29. "Warning signal device" means a tell-tale that provides a failure indication of the AECC/AECD/AECS. 2.30. "Mobile network antenna" means a component that ensures the transmission of data and bidirectional audio signals for voice communication. 2.31. "Multi-task display" means a display on which more than one message can be shown simultaneously. 2.32. "Total permissible mass" means the vehicle's technically permissible maximum mass stated by the manufacturer. 2.33. "R point" means a reference point defined for each seat by the manufacturer in relation to the vehicle's structure, as indicated in Annex 8 to UN Regulation No. 94. Part Ia: Approval of components are intended to be fitted as part of an Accident Emergency Call Device (AECD) 3. Definitions 3.1. "AECC (Accident Emergency Call Component)" means one or a combination of the following components: (a) Control module and related connector(s); (b) Communication module and related connector(s)2 excluding microphones, loudspeakers and connectors;
Mobile network communication device internal failure Item necessary because it is a function: a failure implies that the AECS cannot perform its function. GNSS receiver Electrical connection / module communication failure GNSS receiver Internal failure Mobile network antenna Electrical connection GNSS antenna Electrical connection Crash Control Unit (CCU) Electrical connection e.g. crash detection sensor system, triggering device, … CCU Internal failure If not in good condition, then the automatic emergency call is not possible. If CCU internal failure verification is not part of AECC approval (Part Ia), then it shall be subject to AECD approval (Part Ib) Power supply Electrical connection Dedicated battery is connected SIM not present This item only applies if a removable SIM card is used. Back-up supply (if fitted) The state of charge, threshold for warning at the discretion of the manufacturer Failure if the state of charge is at a critical level according to the manufacturer. Verification of the performance of the AECC malfunction shall be conducted against the manufacturer's specification. This can be either by actual test or simulation. 7.5.2.2. Test procedure Self-test function verification test: 7.5.2.2.1. The following test shall be performed on an AECC on a representative arrangement of components. 7.5.2.2.2. Simulate a malfunction of the AECC system by introducing a critical failure in one or more of the monitored by the self-test function according to the technical documentation provided by the manufacturer. The item(s) shall be selected at the discretion of the Technical Service. 7.5.2.2.3. Power the AECC up and verify that the AECC warning signal device illuminates shortly afterwards or the electrical signal is generated shortly afterward, whichever is relevant. 7.5.2.2.4. Power the AECC down and restore it to normal operation. 7.5.2.2.5. Power the AECC up and verify that the AECC warning signal device does not illuminate or extinguish shortly after initial illumination, or the electrical signal is not generated shortly afterward or is cancelled after being generated initially, whichever is relevant.
