Automatic emergency braking system is an advanced driver-assistance system (ADAS) that detects obstacles on the road and brakes automatically to avoid potential car accidents.
Being part of the “second wave” of active safety systems, AEB uses cutting-edge technology such as sensors, lasers, cameras, GPS and radar. The system undertakes either crash imminent braking (CIB) or dynamic brake support (DBS). CIB applies brakes to slow or stop the car if the driver does not take action. After detecting an issue, the system first tries to warn the driver. If there is no response, it takes control and applies brakes automatically. DBS automatically supplements the driver’s braking action if it is ineffective.
Automatic emergency braking systems can come with different warning and braking stages as well as various levels of deceleration. In addition to the core functionality, there can be more functional interactions, such as closing windows, unlocking doors, transmitting an accident report, etc.
The main purpose of an automatic emergency braking system is to decrease the number of traffic accidents. Since the beginning of its development in the 1970s, the number of traffic fatalities shows a decreasing trend despite the increasing number of road users.
