Who does not know, the fear of a car accident? For many, even greater is the fear of not being able to call for help in the event of an accident (for example due to loss of consciousness or because the smartphone has stayed at home) and then stay undetected in the emergency situation. Because of this horror concept many road users therefore have the desire to retrofit an automatic emergency call system in their vehicle.
Retrofitting the emergency call function - useful?
There is probably no reason to consider this function as meaningless! Therefore, such a retrofit worthwhile in any case. The so-called eCall (Abbreviation of Emergency Call, ie emergency call) is an automatic emergency call system. From 2018, this sensible and in some cases life-saving system must be installed in every new vehicle. However, this feature should not be reserved just for new vehicles, because retrofitting the system in older vehicles also provides a significant increase in road safety and can make our roads safer.
What options for retrofitting are there?
Most systems for retrofitting an emergency call system for cars are based on a smartphone coupled to sensors of the vehicle.
This can be coupled either with an optional, additionally installed crash sensor or with an OBD 2 interface. If an accident occurs, the smartphone coupled with the sensors triggers an automatic eCall via the app. Most of the sensors in the vehicle can be used for these retrofitted systems. It is then often on the sensors that are used for the active safety devices of the vehicle (mostly sensors for triggering the airbags, belt tensioners, rollover protection for convertibles / roadsters etc.). The advantage is that no external sensor (“Crash sensor” that strikes when the vehicle is subjected to high loads) must be installed.
Advantage in all emergency situations - safety plus!
The functions are complemented by a panic alarm or emergency button on the phone, so that the system for medical emergencies (eg heart attack etc.) suitable is. Another great advantage of these systems is that the smartphone can transmit an exact accident report. By using the data of the GPS, an exact accident position can be sent together with the emergency call. The very fast response time of the system is also a plus that can save lives. For the faster an exact accident report is received by the rescue service and important accident data is transmitted to rescue workers, the faster it can be helped directly on site. It may be possible in this way to further reduce the still high number of traffic deaths.
Conclusion! The automatic, retrofitted emergency call makes you safer on the road so that every car driver without this system in his vehicle canusually uncomplicated) Should consider retrofitting. If an OBD 2 interface is available on the car, then your own smartphone (that is usually there anyway) are perfectly used as a helper in distress!
