Road collision detection for the needs of an on-board eCall device

The article describes the problems associated with road collision detection for the purpose of automatic emergency service notification. Upon detecting a collision, the eCall device installed in the vehicle will automatically establish a connection with the Public Safety Answering Point and transmit a set of basic information regarding the vehicle and the location of the incident. Information about airbag deployment will not be used to trigger the alarm, as connecting an eCall device could interfere with the vehicle’s safety systems. It is necessary to develop a method that enables the detection of a road collision based on available data provided by acceleration sensors.1. INTRODUCTION
The European eSafety initiative aims to improve safety and efficiency in road transport. The main element of eSafety is the pan-European eCall project, within which an automatic emergency notification system will be created. Once the system is implemented, every new vehicle will have an on-board eCall device installed, capable of detecting a road collision and automatically calling for help to the scene of the incident. Owners of older vehicles will also be able to install such a device. Currently, the method and protocol for data transmission have already been defined. The minimum set of transmitted data – the so-called MSD packet – has also been specified.
Nowadays, fast data transmission, even over long distances, is not a problem.
ICT technologies enable data transmission using the Internet or mobile networks. (…)
