Autonomous Emergency Braking (AEB)
AEB is an advanced safety technology that can help drivers avoid or mitigate collisions with other vehicles or vulnerable road users.
Multiple real world studies including a recent report from the Insurance Institute for Highway Safety in the United States show that AEB technologies can reduce injury claims by as much as 35%.
AEB systems use forward looking radar, cameras or optical sensors or a combination of these sensors to help quickly and accurately detect impeding vehicles, pedestrians and potentially other obstacles. That information can then be used to apply the brakes to provide up to 1 g deceleration of brake force in an effort to avoid or mitigate collisions.
AEB helps provide constant monitoring of the road ahead and is designed to assist the driver by automatically applying the brakes if they do not respond in an imminent crash situation.
AEB currently exists in three formats responding to different kinds of obstacles:
Applying the brakes in low speed situations where a crash may be imminent in city environments such as queuing traffic, at intersections or in roundabouts.
Applying the brakes to avoid high speed collisions between two vehicles such as on motorways.
Applying the brakes to avoid hitting a pedestrian stepping into the road, even in situations where pedestrians enter the roadway from behind obstructions such as parked vehicles.
As AEB systems utilize differing sensor technologies and underlying algorithms current cars on the market may be fitted with all three of the systems or only a selection.
