Accident simulation for extended eCall system without integration in existing car onboard systems

Abstract

New passenger cars and light commercial vehicles manufactured after March 31st, 2018 should be obligatorily equipped with an eCall system that automatically calls for assistance in the event of an accident. The idea of our research was to develop a system, that will be possible to integrate into older that date vehicles without modification and connection to existing onboard car systems. The system will be able to detect a road accident and beyond standard calls recognize number of vehicle’s travelers and report their vital functions. This paper focuses on a road accident detection part of the whole system. We need to know if an accident took place actually or not, i.e. it might be just a car shock, not collision. In the beginning the state of the art was briefly presented and our direction regarded to the approach was taken based on the worked out model, sensors, equipment and the way of simulation. The second part was focused on the created physical model of test set lab with the designed machine for collision simulation with impact force analysis using selected sensors. At this stage of the project we have built the machine with pendulum and trolley on which we put three-axial accelerometers. We have done some controlled collision with data gathering and the first data analysis of the results.
