In case of a crash, an eCall-equipped car automatically calls the nearest emergency centre. Even if no passenger is able to speak, e.g. due to injuries, a 'Minimum Set of Data' is sent, which includes the exact location of the crash site. Shortly after the accident, emergency services therefore know that there has been an accident, and where exactly.
eCall cuts emergency services response time. It goes down to 50% in the countryside and 60% in built-up areas. The quicker response will save hundreds of lives in the EU every year. The severity of injuries will be considerably reduced in tens of thousands of cases. You can also make an eCall by pushing a button inside the car. Witnessing an accident, you can thus report it and automatically give the precise location. As eCall normally 'sleeps', it does not allow vehicle tracking outside emergencies.
On 28 April 2015 the European Parliament voted in favour of eCall regulation which requires all new cars be equipped with eCall technology from April 2018. eCall will be seamlessly functioning throughout Europe by that time. In the event of a serious accident, eCall automatically dials 112 - Europe's single emergency number.
