It is nice when good things happen automatically. When the good thing that happens automatically can prevent injury or even death, that is even nicer, and that is just what automatic emergency braking is all about.
A car equipped with automatic emergency braking can sense an impending collision and slow the car autonomously. The best result is the automatic braking enables what otherwise would have been a collision to be avoided. Sometimes the physics of the incident makes avoiding a collision impossible, but by slowing the vehicle before impact, the resulting crash can be far less severe. Many current automatic braking systems, especially those on inexpensive cars, are only operative at fairly low speeds, while others work in conjunction with adaptive cruise control systems to bring cars to a full stop automatically when that’s called for (including in normal traffic, not merely in emergencies). Here are the least expensive cars that have automatic emergency braking.
