AEB – Definition & Meaning

AEB is a term that is commonly used in the field of automotive safety. It refers to a technology that helps prevent collisions by detecting obstacles in the path of a vehicle and automatically applying the brakes to avoid a collision. In this article, we will explore the definition and meaning of AEB in greater detail.


AEB stands for Automatic Emergency Braking. It is a safety feature that is designed to prevent or reduce the severity of collisions by automatically applying the brakes when a potential collision is detected. AEB systems use sensors, cameras, and radar to detect obstacles in the path of a vehicle and calculate the distance and speed of those obstacles. If the system determines that a collision is imminent, it will automatically apply the brakes to avoid or mitigate the impact.


The development of AEB technology can be traced back to the early 2000s when car manufacturers began exploring ways to improve the safety of their vehicles. AEB was first introduced by Volvo in 2008, and since then, it has become a standard feature on many new vehicles.
