AUTOMATIC EMERGENCY BREAKING SYSTEM(AES):
Automatic Emergency Braking (AEB) is a combo product of advanced driver assist systems and Electronic Stability Control to slow the vehicle and potentially mitigate the severity of an impact when a collision is unavoidable.
AEB works with or without driver intervention by combining data from forward-looking radar and video systems to provide a complete, accurate and real-time image of the road ahead. AEB can utilize long-range radar (LRR) or mid-range radar (MRR) in combination with a scalable video camera.
Next, brake pressure is applied automatically, providing maximum brake boost immediately once the driver does engage the brakes.
If a driver's steering and braking intervention is not enough to avoid a collision, autonomous emergency braking with maximum brake pressure will be applied to help mitigate the impact. This final action is realized as full ABS braking, and it ensures maximum speed reduction. AEB is the highest escalation step for a safety system to react to a critical situation.
FUNCTIONS OF AEB:
1.Alert the driver to an imminent crash and help them use the maximum braking capacity of the car and
2.Apply the brakes independently of the driver if the situation becomes critical
- The systems use sensors, radar, laser or cameras to monitor for risk and detect potential collisions with other vehicles, pedestrians or hazards.Although AEB systems vary in their functionality, most systems will provide a warning (audible and/or visual) to the driver. AEB systems will also intervene and brake the vehicle automatically if the driver does not respond. Some systems will also charge the brakes in order to provide the most efficient braking and prepare the vehicle for collision by pre-tensioning the seatbelts.Some AEB systems deactivate if they detect avoidance action being taken by the driver.Crash avoidance systems can be classified into three main categories:
- LOW SPEED SYSTEM – this version targets city driving where crashes often occur at low speeds but can cause debilitating injury such as whiplash injuries. Typically, these systems look for the reflectivity of other vehicles and are not as sensitive to pedestrians or roadside objects.
- HIGH SPEED SYSTEM – this version typically utilises long range radar to scan further ahead of the vehicle (up to 200 metres) at higher speeds.
- PEDESTRIANS – these versions use a camera combined with radar to detect vulnerable road users through their shape and characteristics. The way in which pedestrians move relative to the path of the vehicle is calculated to determine whether they are in danger of being struck.
