Brake Assist vs Automatic Emergency Braking: What’s the Difference
The Brake Assist VS Automatic Emergency Braking Debate
Every modern iteration of a vehicle is geared towards bettering its predecessor in some particular capacity. However, the most important aspect of development has focused on enhancing the safety system of the vehicle. Furthermore, today’s cars are equipped with cutting edge, smart technology that minimizes the possibility of accidents and protecting its occupants. Although well defined, two systems often are confused for one another. These are the brake assist vs automatic emergency braking.
Though working towards the same ends, to stop the vehicle, they use different means to do so. Moreover, they rely on different sensors and intervene at different stages of the braking event. But, why is it important to know about them? Well, educating yourself regarding the details of the brake assist vs automatic emergency braking debate will help you make informed decisions. Hence, putting you in the perfect place to make the right decision both economically and functionally.
Brake Assist VS Automatic Emergency Braking: What Is Brake Assist?
Before we get into the specifics of the brake assist vs automatic emergency braking discussion, let’s establish the basics. We need to understand what this piece of technology is before we understand its significance. The brake assist system (often called BA, BAS, EBA) is designed to help drivers stop their vehicles quickly during emergencies. Interestingly, it does not activate on its own. Rather, it uses the driver’s behavior as a cue to initiate.
For instance, when a driver suddenly slams the brake pedal, often during extreme circumstances, the brake assist system activates. Then it identifies panic braking where many drivers fail to apply enough pressure to fully engage the maximum braking force. Here, the brake assists enters the picture to solve the problem by doing the following:
- Detecting rapid brake pedal application
- Increasing the braking pressure automatically
- Ensuring maximum stopping power is delivered
- Working alongside ABS (Anti lock Braking System)
Over time, this system has evolved from a rare advancement to becoming a standard one in modern vehicles. Additionally, it is usually a purely mechanical, electronic, or hydraulic brake assist depending on the design.
Brake Assist VS Automatic Emergency Braking: How It Works?
Essentially, it uses sensors typically located in the braking system or brake pedal assembly to detect emergency braking behavior. Once identified, it then evaluates the following factors:
- The speed at which the brake pedal is pressed
- The force applied to the brake pedal
- The suddenness of the driver’s braking decision
By keeping them under examination, the system instantly identifies whenever they exceed the normal threshold. Then, the brake system boosts the hydraulic pressure. Thus, stopping the car faster than the driver on his own could achieve.
Hydraulic Brake Assist: Often, the brake assists system opt for hydraulic pressure in order to amplify braking force. In the case where it detects an emergency braking event, it proceeds to do the following:
- Pressurizes the brake lines
- Delivers stronger braking force
- Engages the ABS to prevent wheel lock
The reason people prefer it is that it offers high reliability. Working with the vehicle’s existing braking infrastructure, it responds quickly to any and all emergencies.
Brake Assist VS Automatic Emergency Braking: What Is Automatic Emergency Braking (AEB)?
On the other hand, an automatic emergency braking (AEB) system does not rely on the driver at all. Instead, it is an autonomous system that monitors the vehicle’s surroundings and brakes. Moreover, in case it detects the possibility of an accident it works on its own to prevent it. It uses the following sensors and technologies to achieve that:
- Radar
- LIDAR
- Ultrasonic sensors
- Cameras
- Onboard computers and decision making algorithms
All these elements are there to detect the following possibilities and objects:
- Other vehicles
- Pedestrians
- Cyclists
- Obstacles
- Sudden hazards
If the AEB system interprets that an accident is highly likely and the driver is not responding to it, it acts. By applying the brakes automatically with enough force, it reduces or prevents the impact completely. Thereby, keeping both the driver and vehicle safe.
Brake Assist VS Automatic Emergency Braking: How It Works
This system works in three distinct phases.1. Hazard Detection: Here, the sensors pick up the threat of a potential collision risk by identifying the following:
- A stopped car
- A slowing vehicle ahead
- A pedestrian stepping into the road
- A bicycle crossing
Once identified, the system springs into action. It processes the distance, speed, trajectory, and relative movement to measure how dangerous the situation is
2. Warning Phase: If it determines a credible threat, it warns the driver through the following means:
- Visual alerts
- Audible warnings
- Steering wheel vibrations
This provides the driver to avert the danger on his own without any support.
- Applies partial braking (to slow the vehicle)
- Or applies full braking to attempt a complete stop
This significantly reduces the severity of a crash if not prevent it altogether.
Brake Assist VS Automatic Emergency Braking: The Verdict
Now, that we know the specifics of the brake assist vs automatic emergency braking debate, it is time to decide. However, the unique aspect of this discussion is that neither of the systems is inherently better than the other. Simply, they perform two completely different roles.
- Brake assist improves braking when the driver initiates it.
- AEB prevents crashes when the driver fails to respond.
Today, many vehicles integrate both systems in their design to offer maximum protection. AEB has even become mandatory in numerous regions. Meanwhile, brake assist remain an essential braking aid
Conclusion
All in all, the brake assist vs automatic emergency braking discussion is not pointless in the slightest. It helps keep a person informed on the internal mechanics of their car. Thereby, elevating their understanding of how their vehicles work and the roles various parts play in that process. Only once truly aware can a driver understand even the slightest alterations in their car’s performance and get it checked by a technician immediately. Hence, preventing potential danger in its earliest phase.
FAQs
A: It detects panic braking and instantly boosts the hydraulic pressure. This helps make sure that maximum stopping force is utilized to help drivers quickly particularly during emergencies.
A: The short answer is no. Working with ABS, the automatic emergency braking prevents wheel lock. Hence, the system is there to make sure that braking is controlled and without skidding.
A:There are various examples of advanced braking technology. They include ABS,AEB, brake assist, traction control, and electronic stability control to name a few. All these come together to enhance the safety of the vehicle, reducing stopping distances and minimizing the threat of collisions.
A: Essentially, the hydraulic brake assist increases the brake line pressure during emergency braking events. Hence, allowing a vehicle to utilize maximum braking force. This holds true even if the driver does not press the pedal hard enough.
