What Is An Automatic Braking System?


How does an Automatic Braking System work?

An Automatic Braking System, also known as Autonomous Emergency Braking (AEB), is a safety feature designed to prevent or reduce the severity of collisions by automatically applying the brakes when it detects an imminent collision. This advanced technology uses a combination of sensors, cameras, and radar to continuously monitor the road ahead and the surrounding environment, allowing the system to react quickly and effectively.

When the AEB system detects a potential collision, it sends a signal to the vehicle’s braking system. This signal triggers the brakes to engage, either partially or fully, depending on the severity of the situation. The system calculates the necessary braking force based on factors such as the speed of the vehicle, the distance to the object or vehicle in front, and the relative speed difference between the two.

The AEB system primarily relies on various sensors, such as forward-facing radar, cameras, or lidar (light detection and ranging), to gather data about the surroundings. These sensors continuously scan the road, detecting potential obstacles like vehicles, pedestrians, or other objects in the path of the vehicle.

Once an obstacle is detected, the AEB system assesses the risk of a collision. It uses complex algorithms to analyze the distance, relative speed, and trajectory of the obstacle and compares it to the vehicle’s current speed and direction. If the system determines that a collision is imminent and the driver hasn’t taken appropriate action, it will automatically apply the brakes to reduce the impact or avoid the collision altogether.

Some advanced AEB systems also include features such as pedestrian detection, cyclist detection, and intersection assist. These additional capabilities further enhance the safety of the system by detecting and reacting to vulnerable road users or potential collision scenarios in complex driving environments.

It is important to note that while AEB systems are designed to assist drivers and prevent collisions, they are not a substitute for attentive and responsible driving. Drivers must always remain focused on the road and be prepared to intervene if necessary.

Types of Automatic Braking Systems

Automatic Braking Systems can be classified into several types, each with its own capabilities and specific applications. Let’s take a closer look at the most common types:

  1. Forward Collision Warning (FCW) with Autonomous Emergency Braking (AEB): This is the most basic type of AEB system. It uses sensors to detect potential collisions and provides a warning to the driver through visual alerts, auditory alerts, or haptic feedback like vibrations in the steering wheel. If the driver fails to respond, the system will automatically apply the brakes to prevent or mitigate a collision.
  2. City-speed AEB: This type of AEB system is specifically designed for urban driving, where there is a higher risk of low-speed collisions, such as in stop-and-go traffic. It can detect pedestrians, cyclists, and stationary objects at low speeds, issuing warnings and applying the brakes to avoid or minimize the impact of a potential collision.
  3. High-speed AEB: As the name suggests, this type of AEB system is optimized for high-speed driving scenarios, such as on highways or open roads. It can detect vehicles ahead and calculate the relative speed and trajectory, providing warnings and applying the brakes if necessary to reduce the risk of rear-end collisions at higher speeds.
  4. Pedestrian AEB: Pedestrian detection is a crucial feature in AEB systems, as pedestrian-related accidents are a significant concern. This type of AEB system uses advanced sensor technology to detect pedestrians and automatically applies the brakes if there is an imminent risk of a collision, helping to protect vulnerable road users.
  5. Cyclist AEB: Similar to pedestrian AEB, cyclist AEB systems use sensors to detect cyclists on the road. The system can differentiate between cyclists and other objects, issuing warnings or automatically applying the brakes when necessary to prevent collisions with bicycles.

It’s worth noting that not all vehicles come equipped with the same type of AEB system. The availability and functionality of these systems may vary depending on the vehicle’s make, model, and trim level. Therefore, it is essential for consumers to research and understand the specific AEB features offered by different car manufacturers before making a purchase.
