2.2. Enhanced eCall
eCall is activated automatically when i-VITAL sensors detect an accident. Once the eCall is triggered, the system
will establish a data and audio connection with the respective service center sending details such as time of incident,
accurate position, travel direction, and health data. An eCall can also be triggered manually by using the i-VITAL
application. To enhance the eCall with vital sign data, the common MSD content (Minimum set of Data as defined in
EN 15722:2011 [5]), especially the optional data block will be adapted and specified accordingly.
