Automatic Emergency Braking

Automatic Emergency Braking

Automatic emergency braking (AEB) is a relatively new concept that’s now included in virtually all new vehicles. But what exactly is it? And how does it work?

Read on to discover everything you need to know about AEB, how it works, and some of the different names by which it’s known.

What is automatic emergency braking?

In its most basic terms, automatic emergency braking is a safety system that activates the brakes if an imminent collision is detected. This is done without any intervention from the driver. In addition, it can also increase the force of braking if the system determines that the driver isn’t hitting the brake pedal hard enough to prevent an impact.  

How does automatic emergency braking work

There are different systems in use that vary from manufacturer to manufacturer. Some use sensors, others use cameras. Some cars are equipped with both. Whatever method is used, these constantly scan ahead, and the data is returned in real-time to the car’s onboard computer. If a potential collision is detected, the AEB will be triggered.

The system is usually complemented by what’s known as Forward Collision Warning (FCW). Should a hazard be detected where the AEB might need to be activated, then a warning tone will sound. This happens just before the automatic emergency braking comes into play, giving you time to hit the brakes yourself or, if you don’t, not be shocked by a sudden deceleration episode.

Advantages, driver control, and servicing

The most obvious advantage of automatic emergency braking is a reduction in accidents or a lessening of the impact forces when they occur.

At present, most car AEB systems allow a driver to disengage the system. Others let you change the sensitivity, so you can personalize how far ahead the car scans and when it might activate. As semi and fully autonomous driving inches ever towards reality, whether this will be the same in the future remains to be seen.

Of course, as we become more accustomed to such safety features (and dare we say, complacent), ensuring they work as expected is vital. This means that AEB systems should be regularly serviced alongside every other mechanical element of a vehicle. 

Automatic emergency braking by other names

Different manufacturers like to use their own terminology for AEB. However, they all boil down to the same thing—a vehicle that senses danger ahead and can automatically brake to prevent or lessen the impact of a collision.

Some of the terms you might see include:

  • Forward Collision Mitigation (Mitsubishi)
  • Active Brake Assist (Mercedes)
  • Forward Collision-Avoidance Assist (Genesis)
  • Safety Collision Avoidance Technology (Volvo)
  • Autonomous Emergency Braking (Maserati)
  • Frontal Collision Warning with City Collision Mitigation (BMW)
  • Emergency Braking (Jaguar)
  • Pre-Collision System with Automatic Emergency Braking (Lexus)
  • Porsche Active Safe (Porsche)
  • Front Assist (VW)
  • Audi Pre-Sense Front or Audi Pre-Sense City (Audi)
