What is Forward Emergency Braking (FEB) or Autonomous Emergency Braking (AEB) and How To Use It

Forward Emergency Braking (FEB), also known as Autonomous Emergency Braking (AEB), is an advanced safety feature found in many new cars. FEB takes the concept of Forward Collision Warning (FCW) a step further by not only alerting the driver to an impending collision but also automatically applying the brakes to mitigate or prevent a front-end collision. This system is designed to work in conjunction with FCW and acts as an additional layer of protection to enhance road safety.

How Forward Emergency Braking Works

1. Sensor Fusion: Similar to FCW, FEB relies on a combination of sensors such as radar, lidar, and cameras to continuously monitor the road ahead. These sensors gather data on the distance and relative speed between the car and potential obstacles, including other vehicles, pedestrians, or objects.
2. Collision Detection: FEB’s algorithm analyzes the incoming data to determine if a collision is imminent. It takes into account factors such as the closing speed, time to impact, and other relevant parameters.
3. Emergency Brake Activation: If the system determines that a collision is likely and the driver has not taken appropriate action, FEB engages the brakes autonomously. It applies the brakes with sufficient force to reduce the severity of the impact or, in the best-case scenario, prevent the collision entirely.

How to Use Forward Emergency Braking in New Cars

Using Forward Emergency Braking in new cars is generally a seamless process. The system is typically pre-configured and ready to operate once the vehicle is turned on. However, drivers should be aware of a few essential points to ensure they can use FEB effectively:

1. Enable the FEB System: Check that the FEB system is activated in your car’s settings or infotainment system. It is usually part of a suite of advanced driver-assistance systems (ADAS) and may be labeled as “Forward Emergency Braking,” “Autonomous Emergency Braking,” or “Automatic Emergency Braking.”
2. Understand the Limitations: While FEB is a valuable safety feature, it has limitations. It may not be effective in all driving conditions or scenarios. For example, the system may have reduced functionality in heavy rain, snow, or low-visibility situations. It’s essential to be aware of these limitations and not overly rely on the system’s capabilities.
3. Stay Attentive: Even with FEB engaged, it’s crucial for the driver to remain attentive and ready to take control of the vehicle at any time. FEB is designed to assist the driver, but it should not replace responsible driving habits.
4. Keep the Sensors Clean: The sensors that enable FEB to function optimally need to be clean and unobstructed. Regularly inspect and clean the front-facing sensors to ensure their accuracy and proper operation.
5. Practice Safe Driving: While FEB can help mitigate the consequences of a front-end collision, it’s essential to practice safe driving habits, maintain a safe following distance, and obey traffic laws at all times.

Forward Emergency Braking is a significant advancement in automotive safety technology, potentially saving lives and reducing the severity of accidents. As with any safety feature, understanding its capabilities and limitations is key to using it effectively and responsibly.
