Abstract
The article considers a possible improvement of road vehicle safety by using eCall – a system which initiates an emergency call in case of traffic accident. A possible way of better description of a frontal impact accident of a vehicle is examined and enriched by the information from the onboard e-call unit. In this article, we analyze results of frontal crash tests with different types of barriers and overlapping area and look for the correlation between the individual vehicle and collision parameters in order to provide a better description of the severity of the accident by the eCall system. The relation among the selected parameters is described using the correlation analysis.
Highlights
In a long-term timeframe, there is a noticeable decrease in the amount of road accidents, casualties and fatal victims of road accidents in Europe
Based on the information obtained from passive safety systems installed in the vehicle and additional eCall system sensors, the eCall system automatically detects a road accident and sends a Minimum Set of Data (MSD) message to the emergency service and at the same time establishes a voice communication with 112 service
Analysis of the crash tests results was made based on correlation analysis between selected parameters presented in Table 1 and 2, considering if it is suitable to use them for estimation of the severity of the accident by eCall system
Summary
In a long-term timeframe, there is a noticeable decrease in the amount of road accidents, casualties and fatal victims of road accidents in Europe. It is mostly achieved thanks to newly accepted legislation measures increasing road safety and minimizing consequences of road accidents. One of these measures is a mandatory installation of the eCall system – an emergency call system in case of a road accident. Based on the information obtained from passive safety systems installed in the vehicle and additional eCall system sensors, the eCall system automatically detects a road accident and sends a Minimum Set of Data (MSD) message to the emergency service and at the same time establishes a voice communication with 112 service. The operator of the emergency service decides on the measures and safety services dispatched to the accident site based on the information obtained in the MSD message and from oral communication with passengers of the crashed vehicle. This was concluded based on results of series of crash tests
