Automatic emergency braking (AEB) systems have become a crucial component in modern vehicle safety, designed to prevent or mitigate collisions by automatically applying the brakes. This technology has evolved significantly over the years, becoming a standard feature in many new vehicles. This article explores the historical development of AEB systems, highlighting key milestones and advancements that have shaped their current form.
Early Developments in Braking Technology
The journey towards
automatic emergency braking systems began with the development of basic braking technologies. One of the earliest advancements was the anti-lock braking system (ABS), which maximizes braking friction on slippery surfaces or during emergency maneuvers. ABS laid the groundwork for more advanced systems by preventing wheel lock-up and maintaining vehicle control during hard braking.
In the 1990s, the concept of emergency brake assist (EBA) emerged. This system was designed to increase braking effectiveness when a driver executed a panic stop. By interpreting the speed and force with which the brake pedal was pushed, EBA could detect emergency stops and apply maximum braking effort, reducing stopping distances and the likelihood of accidents.
The Introduction of Autonomous Emergency Braking
The first modern forward collision avoidance system was patented in 1990, marking a significant step towards autonomous emergency braking. By the mid-1990s, radar-based systems were being developed, allowing vehicles to detect potential collisions and warn drivers. These systems evolved into what we now know as AEB, which can autonomously apply brakes when a collision is imminent.
In the early 2000s, AEB systems began to be introduced in the market. By 2008, AEB was available in the British market, and various car manufacturers started incorporating these systems into their vehicles. The technology continued to improve, with systems becoming more sophisticated and capable of detecting a wider range of potential hazards.
Regulatory and Commercial Advancements
The widespread adoption of AEB systems was significantly influenced by regulatory and commercial developments. In 2016, the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety announced that 99% of U.S. automobile manufacturers had agreed to include AEB systems as standard on virtually all new cars sold in the U.S. by 2022. This agreement accelerated the rollout of AEB technology, with projections suggesting it could prevent thousands of collisions and injuries annually.
In Europe, similar agreements and regulations have been established, with the United Nations Economic Commission for Europe (UNECE) mandating AEB systems for new heavy vehicles starting in 2015. These regulatory measures have played a crucial role in making AEB systems a standard feature in vehicles worldwide, enhancing road safety and reducing accident rates.
