Vehicle emergency call systems make an emergency call in the event of an accident – either automatically or at the touch of a button. eCall, for example, triggers a call to the single European emergency number 112. The system sends a data record to an emergency call center, which provides information about the accident situation. The minimum data record contains: Time of accident Place of accident (coordinates) Direction of travel (relevant for motorways and tunnels) Vehicle ID Service Provider ID eCall qualifier (information whether eCall was triggered automatically or manually) In addition, on-board security systems can transmit other data, for example: Number of occupants Seriousness of the accident Condition of the seat belts: fastened or not fastened Possible rollover of the vehicle
