eCall – Emergency Call System

eCall is a project intended to bring rapid assistance to motorists involved in a collision anywhere in the European Union. 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.

Embitel, along with a silicon vendor, has created an evaluation platform to demonstrate eCall functionality. The chipset offered by the silicon vendor, which combines GPS and ARM core is used to create the proof of concept system.

System Overview:

  • eCall is an emergency call either generated  manually by vehicle occupants or automatically via activation of in-vehicle sensors when an accident occurs.
  • When activated, the in-vehicle eCall system establishes a 112-voice connection directly with the relevant PSAP (Public Safety Answering Point).
  • A minimum set of data (MSD) – including key information about the accident such as time, location and vehicle description – is sent to the PSAP operator
  • Embedded solution with in-built network access device(NAD)
  • SIM support
  • Backup power supply
  • Proof of concept in partnership with a Bangalore based silicon manufacturer
Tools
  • SST230 Micro-controller core 
  • IAR/ Code Sourcery GNU Tool chain
  • GPS, Bluetooth, CAN
