eCall

Technical Articles

eCall is a European initiative intended to bring rapid assistance to motorists involved in a collision anywhere in the European Union. The eCall initiative aims to deploy a device installed in all vehicles that will automatically dial 112 in the event of a serious road accident, and wirelessly send airbag deployment and impact sensor information, as well as GPS coordinates to local emergency agencies.

eCall provides reliable full-duplex data transmission between In-vehicle System (IVS) and Public Safety Answering Point (PASP) in addition to emergency voice call via the cellular network and can be initiated either automatically or manually. The eCall In-band modem ensures reliable data transmission of the eCall Minimum Set of Data from IVS to PSAP via the voice channel of cellular and PSTN network. In the event of a vehicle collision, the in-band modem transmits vehicle location, airbag deployment, and other relevant information timely and reliably from the IVS over the cellular network voice channel to PSAP. As soon as the PASP received the emergency call, it will dispatch rescue assistance to the accident site, which can shorten response time and save lives.

Requirements on the Products for eCall

● High Reliability and Sensitivity To ensure Minimum Set Data can be timely and reliably sent to the PASP from the IVS after strong collision, high reliability and sensitivity of the products are of prime importance in addition to supporting backup battery.
● Remotely Upgrade Firmware The firmware in the products can be updated remotely via FOTA function, which can dramatically reduce maintenance cost.
● Compact Form Factor The products with tiny size can be easily embedded in the automotive applications.
