eCall – Saving Lives
白皮书
In 2017, car accidents across Europe killed 25,300 people and injured 135,000 more. To reduce these numbers, the European Union (EU) passed legislation in 2015 that requires all new cars sold after March 31, 2018, to come equipped with a device called eCall (emergency call).
An eCall device automatically alerts emergency services (Figure 1) once an invehicle sensor (IVS) or processor, such as an airbag, detects a crash. The device dials the European emergency number 112; establishes a telephone link to the appropriate emergency call center, known as a public safety answering point (PSAP); and sends details, known as a minimum set of data (MSD), about the accident. The MSD includes information about the time of the accident, the position and location of the crashed vehicle, and the direction of travel. Drivers, passengers, and witnesses can also trigger a call by pressing the eCall buttons in their automobiles.
