Guidelines 1/2020 on processing personal data in the context of connected vehicles and mobility related applications
Section 3.2 eCall
128. In the event of a serious accident in the European Union, the vehicle automatically triggers an eCall to 112, the EU-wide emergency number (see section 1.3 for further details) which allows an ambulance to be sent the place of the accident promptly according to regulation EU 2015/758 of 29 April 2015 concerning type-approval requirements for the deployment of the eCall in-vehicle system based on the 112 service, and amending Directive 2007/46/EC.
129. Indeed, the eCall generator installed inside the vehicle, which enables transmission via a public mobile wireless communications network initiates an emergency call, which is either triggered automatically by vehicle sensors or manually by the vehicle occupants only in the event of an accident. In addition to activation of the audio channel, the second event triggered automatically as a result of an accident consists in generating the Minimum Set of Data (MSD) and sending it to the public safety answering point (PSAP).
