According to Postal, although the basic regulation has already been in force since July 6, 2022, for new vehicles in development, as Autogear explains that the obligation will be extended to all passenger cars and commercial passenger vehicles on sale in the European Union from June 7, 2024. It is worth mentioning that the EDR installation is exclusive to new cars.

What is EDR and how does it work

The Event Data Recorder is one of the eight mandatory safety systems and its function is to record crucial data in the 5 seconds before an accident and in the 0.03 seconds after. The information collected, anonymous in nature, will only be stored in specific circumstances, helping to determine the causes and responsibilities in the event of an accident.

Typically integrated into the airbag control unit, the EDR is the size of a small portable battery and activates automatically when the airbags and seat belt tensioners come into play. Furthermore, it starts recording data when the vehicle's active hood is activated or when a lateral or longitudinal speed change greater than 8 km/h in 0.15 seconds is detected.

It is important to highlight that EDR does not record images or audio, focusing exclusively on data related to driving. Among the variables monitored are speed, accelerator pressure, engine speed, turning angle, brake action, and airbag activation, among others.

This measure aims to reinforce road safety and provide a more detailed analysis in cases of accidents, contributing to safer and more responsible driving.
