EU-27 when fully deployed, and furthermore to reduce the severity of injuries, to bring significant savings to the society in and to reduce human suffering. Emergency calls made from vehicles or mobile telephones using wireless technologies, can assist with the objectives of significantly reducing road deaths and injuries, but drivers often have poor (imprecise) location-awareness, especially on interurban roads or abroad. Additionally, in many situations the car occupants may not be in a position to call using a normal mobile phone. The situation is worse for those travelling abroad. A high (and increasing) number of vehicles travelling outside their home country is thus also contributing to the need for automated emergency call system in vehicles. In EU there are over 100 million trips to another EU country per year (EU-15), 65 % of the people feel less protected while abroad and most do not know which number to call in an emergency (in some countries over 60 %). Language problems are pertinent and may render proper communication difficult .Yet, in the most crucial cases, the victim(s) may not be able to call because they have been injured/trapped, do not know the local number to call, and in many cases, particularly in rural situations and late at night, there may be no witnesses who happen to have a mobile phone and a sense of community. eCall, in the context of "Road Traffic and Transport Telematics" (otherwise known as "Intelligent Transport Systems" or "ITS"), can be described as a "user instigated or automatic system to provide notification to public safety answering points, by means of wireless communications, that a vehicle has crashed, and to provide coordinates and a defined minimum set of data, and where possible a voice link to the PSAP. The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate the notification of a traffic accident, wherever in the European Union and associated countries, with the same technical standards and the same Quality of Services objectives of other emergency (TS12) services. This European Standard specifies the "Minimum Set of Data" (MSD) to be transferred by such an in-vehicle eCall system in the event of a crash or emergency. NOTE The communications media and means of transferring the eCall MSD are not defined in this European Standard. The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this European Standard may involve the use of a patent concerning eCall given in this European Standard. CEN takes no position concerning the evidence, validity and scope of this patent right. SIST EN 15722:2011

emergency call generated either automatically via activation of in-vehicle sensors or manually by the vehicle occupants; when activated it provides notification and relevant location information to the most appropriate 'Public Safety Answering Point’, by means of mobile wireless communications networks, carries a defined standardised Minimum Set of Data notifying that there has been an incident that requires response from the emergency services, and establishes an audio channel between the occupants of the vehicle and the most appropriate 'Public Safety Answering Point'

6 Requirements 6.1 Concepts and formats 6.1.1 MSD data concepts NOTE The minimum set of data is important information to assist the provision of the most appropriate services to the crash or emergency site and to speed up the response. The minimum set of data makes it possible for the PSAP operator to respond to the eCall even without the voice connection. The "Minimum Set of Data" shall be a direct, timely message to the PSAP operator receiving the emergency call. 6.1.2 Format definition of MSD data concepts The definitions shown in this standard are shown below in semantic representation. Data presentation shall be as determined in 6.1.4. The real position of the element in the data-stream is defined by the ASN1 definition in Annex A; elements therefore do not necessarily start or end on a byte boundary. NOTE The information elements in the minimum set of data have been selected on the basis of their relevance in an emergency rescue situation. 6.1.3 Sequence of MSD data concepts The sequence of data presentation shall be as specified in 6.2, presented as defined in 6.1.4.
TestCall type: true = Test call false = Emergency
PositionCanBeTrusted: true = Position can be trusted false = Low confidence in position Precise vehicle type encoding is defined in Annex A. The supported vehicle types are as follows: passenger vehicle (Class M1) buses and coaches (Class M2) buses and coaches (Class M3) light commercial vehicles (Class N1) heavy duty vehicles (Class N2) heavy duty vehicles (Class N3) motorcycles (Class L1e) motorcycles (Class L2e) motorcycles (Class L3e) motorcycles (Class L4e) motorcycles (Class L5e) motorcycles (Class L6e) motorcycles (Class L7e) NOTE 1
Vehicle definitions class M, N according to directive 2007/46/EC; class L according directive 2002/24/EC. NOTE 2
The position confidence bit is to be set to “Low confidence in position” if the position is not within the limits of ± 150 m with 95 % confidence. 4 Vehicle identification String M VIN number according to ISO 3779

The following storage types are supported:
 Gasoline tank  Diesel tank  Compressed natural gas (CNG)  liquid propane gas (LPG)  Electric energy storage (with more than 42 v and 100 Ah)  Hydrogen storage
All bits shall be set to zero to indicate an unknown or other type of energy storage. NOTE 1
This information may be unreliable if there has been a change of vehicle propulsion type (e.g. from gasoline to CNG). NOTE 2
More than one bit may be set if there is more than one type of energy storage present.
