Automatic emergency braking (AEB) systems use radar, cameras, or lasers to detect obstacles in the road and can automatically apply the brakes if the driver does not react in time. AEB systems are becoming increasingly common on new cars and are expected to become standard equipment in the United States by 2022.

There are several major automakers that have implemented automatic braking systems in their vehicles. These include:

* Toyota

* Honda

* Subaru

* Mazda

* Volvo

Automatic braking is an important technology that has the potential to save the lives of many drivers and pedestrians. It works by continuously scanning the road ahead for obstacles. When an obstacle is detected, the system will automatically apply the brakes if the driver does not take action.

There are some limitations to automatic braking systems, however. For example, they may not work well in all weather conditions, and they may not be able to detect all obstacles. Drivers should still be aware of their surroundings and should not rely solely on automatic braking systems to avoid accidents.

Overall, automatic braking systems are a valuable safety feature that can help to prevent accidents. As the technology continues to develop, it is likely to become even more effective in the future.

Here are some additional details about automatic braking systems:

* They typically work at speeds of up to 50 mph.

* They can detect cars, pedestrians, and bicycles.

* They can also be used to prevent rear-end collisions.

* Some systems can also detect traffic signs and signals.

* Automatic braking systems are becoming more common on new cars and are expected to become standard equipment in the United States by 2022.
