In terms of safety, the automotive industry has shifted into high gear, with various advanced features leading the charge. Autonomous Emergency Braking (AEB) is the most significant among these innovations. This system enhances safety by automatically applying brakes in emergencies to prevent collisions.
AEB has altered how vehicles identify and react to potential dangers on the roads. It responds faster than human reflexes, highlighting major advancements in automotive safety.
Apart from the prevention of accidents, this system also enhances drivers’ confidence to a huge extent. Let’s explore the different aspects of autonomous emergency braking in cars to understand how it ensures a safe driving experience.
Autonomous Emergency Braking (AEB) Explained
AEB is a modern car safety feature that applies brakes to the detection of obstacles like cars or pedestrians. This collision avoidance system works by engaging brakes when it detects that the driver is not taking action. AEB either slows down the car or brings it to a complete halt to fulfil its purpose.
AEB has different names, such as automatic emergency braking, brake assist or collision mitigation braking. The primary function of this feature, regardless of the name, remains the same.
Types of AEB Systems
Several types of AEB systems cater to different driving scenarios for utmost safety. Here are some of the most common types of autonomous emergency braking systems in cars:
Forward AEB
Forward automatic emergency braking helps prevent front-end collisions by collaborating with the Forward Collision Warning (FCW) system. The FCW system warns the driver when it detects an obstacle ahead. If the driver doesn’t take action promptly, forward AEB engages to avert front-end collision.
Rear AEB
Rear automatic emergency braking is enabled when a vehicle detects an obstacle while reversing. This system consists of rear cross-traffic alerts that identify moving vehicles behind the car. Rear AEB helps significantly in reducing accidents while reversing.
AEB with Pedestrian Detection
AEB with pedestrian detection has a similar function as forward AEB. However, apart from detecting vehicles, this system can also alert drivers about pedestrians on the way.
City-Speed AEB
City-Speed AEB is ideal when driving in urban areas or heavy traffic. This system is developed for low-speed driving areas lowering the probability of slow-speed accidents.
Highway-Speed AEB
Highway-Speed AEB is engineered for high-speed driving routes such as highways. It incorporates advanced sensors that detect distant objects and slow down the car to avoid collision.
AEB Working Principle
AEB systems are composed of various sensors, cameras and radar to identify potential risks on the road. Let’s take a look at how these systems work to enhance safety:
Continuous Monitoring
AEB systems are able to detect vehicles and objects due to the radar sensors and cameras placed on the car grille, windshield or bumper. This way the system is always in the know of the vehicle’s surroundings and potential dangers. These components work together to measure the speed and distance of the obstructions in the vehicle’s pathway.
Signalling Alerts
The AEB system sends an alert to the driver when the distance between the car and the obstacle decreases. These alerts may be sent via audio signal, such as a loud beeping noise or visual prompts on the dashboard. The purpose of these alerts is to provide drivers with enough time to take appropriate action.
Engaging Brakes
If the driver takes no action after receiving the alert, the AEB system automatically applies car brakes to prevent collision. The force of braking depends on the speed of the car and the distance from the obstacle.
Role of ABS (Anti-Lock Braking System)
An anti-lock brake system (ABS) works together with an AEB to ensure safe braking during emergencies. When the AEB system applies the brakes, the ABS stops the wheels from locking up. This helps avoid skidding and keeps the driver in control of the steering. Additionally, other types of car braking systems, like hydraulic and mechanical systems, also enhance safety.
Pros and Cons of Autonomous Emergency Braking (AEB) in Cars
AEB is among the exceptional safety systems that help considerably lower the rate of car collisions. However, despite its benefits, the AEB system also has some disadvantages. The pros and cons of autonomous emergency braking in cars are as follows:
Pros
- Collision Prevention: Decreases the probability of collision due to distracted driving or delayed responses.
- Damage Mitigation: Lowers the intensity of the impact in unavoidable collisions.
- Pedestrian Safety: Ensures pedestrian safety in urban settings.
- Driver Confidence: Promotes a worry-free driving experience.
Cons
- Abrupt Braking: Sudden braking may alarm passengers and increase the chances of rear-end collision.
- Expensive Feature: AEB systems are limited to premium car models that require a larger budget.
FAQs
What is the difference between AEB and FCW?
FCW alerts the driver about an obstacle in the way. On the other hand, AEB applies the brakes automatically if the driver doesn’t respond.
Which sensor does autonomous emergency braking AEB use?
The AEB system uses a radar sensor in combination with a front windshield camera that helps detect obstructions on the road.
What is an AEB warning light?
The AEB system has a yellow warning light that illuminates when there’s a fault in the system.
That wraps up the key points of an autonomous emergency braking system in cars for safety. This system minimises road accidents significantly. Furthermore, the different types of AEB cater to the varying driving situations, enhancing safety while driving. Apart from ensuring safety, it has also become a crucial feature that boosts driver confidence.
