Automatic Emergency Braking monitors the proximity of vehicles in front, detecting potential collisions towards the front. Braking is automatically applied to avoid or reduce the collision effects.

If a radar or video camera sensor detects an obstacle ahead of the moving car, the system prepares the braking system for emergency braking and warns the driver, usually with audio visual or other sensory alerts, such as steering wheel feedback.

If the driver doesn’t respond, the system performs partial braking in order to increase the time available to react. As soon as the driver steps on the brakes, the system helps to avoid an accident by calculating the braking power needed and increasing the braking power applied should the driver brake too gently.

If the driver still fails to respond and the system detects that a collision is unavoidable, it performs emergency braking. This helps to greatly mitigate the consequences of the accident.

As with many ADAS system, it’s not always reliable (objects which are elevated or are not picked up by forward facing sensors may not be detected), so the severity of accident in the event of system failure is likely to be high.
