The **AEB (Autonomous Emergency Braking)** system is an active safety device in vehicles responsible for performing an **emergency braking** when necessary. This system uses a **radar** to calculate the distance between your vehicle and the one in front. If it detects that the distance is too short and there is a risk of collision, the system will first warn you with a voice and a sound. If you do not react to these signals, the AEB will automatically execute an emergency braking to avoid the accident.

This system is different from other safety devices, such as the **EBD (Emergency Brake Warning)**, which only warns the driver that the vehicle in front is braking in an emergency, but does not perform the braking itself. Therefore, the AEB is the system that effectively carries out the **emergency braking** when necessary.
