Emergency call system definition via robustness structure in vehicle applications

The European Union Parliament introduced the legislation EU-2015/758 which includes the obligation of emergency call system equipped vehicles in the European countries with the starting date of 31 March 2018. After the regulation is started to be applied, new system updates and modifications in the vehicle systems are released. Emergency call (eCall) system can be applied to the vehicle structures with different types such as manual eCall device, automatic eCall device including control unit and/or measurement unit. When manual eCall device is triggered manually, automatic eCall device is activated automatically when an accident occurs. In this point of view, emergency call structure in the vehicle system is defined with its robust working principles including boundary diagram, P-diagram, and verification methods which enable the system to work properly.
