Automatic Emergency Breaking (AEB) has just been declared a requirement for all new cars in Europe to reach a maximum safety rating. The same requirement is said to be applied in the US by 2022. New sensing technologies are being applied to AEB systems constantly to improve safety in all cars, and with the current state of development of driverless cars, AEB technology is quickly improving.
Fusion of different sensing technologies is critical for the further development of AEBs. Some of the different sensing technologies currently being used to produce better AEBs are radar, LiDAR, ultrasonics, and numerous types of cameras. These devices are being used to gather data so that programs can, with numerous types of inputted data, make the best possible decisions for how cars should break in emergency situations. Recreating the 360 degree surrounding area around the car is crucial in ensuring the effectiveness of AEBs, and AEB systems try to not only produce a simulation of the surrounding area, but monitor the motion, temperature, and sounds of objects around the car, as well as simulating different outcomes based on different motions that the car could perform to ensure the most safe solution. Also, all of this must be done as quickly as possible to avoid missing potentially life-saving opportunities.
Europe has decided, as of 2018, that AEBs are advanced enough now that all new cars produced must have them. One reason for this is the incorporation of new millimeter-wave radars that will be able to improve the effecincy of all AEBs. This decision has also led the US to plan on implementing the same regulations by the year 2022.
