Learn How Automatic Emergency Braking Helps You Avoid Collisions

Automatic Emergency Braking (AEB) is a critical component of Advanced Driver Assistance Systems (ADAS), designed to enhance vehicular safety and mitigate the risk of collisions. AEB uses a combination of sensors, including radar and cameras, to detect imminent crash scenarios. When such a situation is identified, the system automatically applies the vehicle’s brakes to either reduce the severity of the impact or prevent the collision altogether.

The function of AEB is grounded in the principles of real-time data processing and decision-making algorithms. These systems rely heavily on advanced machine learning techniques and sensor fusion to accurately perceive the environment around the vehicle, distinguishing between various obstacles, such as other vehicles, pedestrians, and static obstacles.

Different type of AEB systems:

Low Speed AEB: Sometimes referred to as city speed AEB. This system is particularly useful in urban environments, working effectively at speeds below 55 mph. It’s designed for those close encounters when you’re navigating through traffic.

Highway Speed AEB: As you might guess, this one kicks in at speeds above 55 mph. It’s engineered to detect potential collisions at higher speeds, giving you that much-needed peace of mind on the open road

Pedestrian AEB: This is where technology gets really interesting. This system can detect pedestrians in your path and apply the brakes to avoid hitting them. Safety is paramount, right? The fact that we have AEB systems capable of recognizing people is a step forward in automotive safety.

When comparing different models, it’s essential to note that currently, the National Highway Traffic Safety Administration (NHTSA) challenge only includes low-speed AEB with Forward Collision Warning. While many cars today may have advanced AEB features, not all are standardized or included in safety regulations, which can affect their availability in vehicles.

Why Need Automatic Emergency Braking?

Research shows that vehicles outfitted with AEB features, combined with Forward Collision Warning (FCW) systems, are much less likely to rear-end fellow drivers. In fact, studies indicate that the combination can reduce crash rates by a whopping 50%. Even without AEB, vehicles equipped solely with FCW still experience a noteworthy 27% reduction in rear-end collisions.

So, what about the impact of AEB on crash severity? Let’s picture a scenario: an AEB-equipped Mercedes-Benz hitting a stationary Chevrolet. The Mercedes-Benz, thanks to AEB, reduces its speed by 13 mph before impact, resulting in about $5,700 in damages. The stationary car? It clocks in at $28,000 in damages. That’s a complete loss! Just imagine the implications of this technology in preventing severe injuries. NHTSA Deputy Administrator James Owens stated it well: “Automatic emergency braking can help prevent or reduce the severity of crashes, which also reduces the risk of injury.”

Pros of AEB Technology:

Significant Reduction in Accidents: As previously mentioned, AEB can reduce rear-end collisions by up to 50%.

Lower Collision Severity: AEB can decrease the impact speed, leading to less vehicle damage and potentially fewer injuries.

Enhanced Safety Ratings: Vehicles with AEB tend to score better in safety ratings, which is definitely something to consider.

Cons of AEB Technology:

Cost: Vehicles equipped with advanced AEB systems often come with a higher price tag.

False Sense of Security: Drivers may over-rely on AEB features, which could be dangerous if they neglect basic safe driving practices.
