Automatic emergency braking is designed to stop or slow a vehicle before it hits an object in its path. When sensors or cameras detect an object ahead, determine that the vehicle is closing on it at too fast a rate of speed, and establish that the driver is taking no action to slow or stop the vehicle, it automatically activates the brakes. braking in cars.jpg Some systems work only at lower speeds, helping to prevent fender benders in traffic. Others work at higher speeds, slowing a vehicle before an impact in order to reduce injuries and prevent deaths. Some react to pedestrians, cyclists, and animals, while others don't. Increasingly, automatic braking is available when reversing, too. Depending on the design of the system, automatic emergency braking relies on cameras, radar, or sensors. When these technologies identify an object in the car's path and the potential for a collision with that object, they automatically activate the braking system. car braking system.jpg These systems do not guarantee that you will avoid a collision. Rather, under normal situations, they will try to stop your vehicle in time. At a minimum, they slow your vehicle to reduce the severity of the impact. braking system in cars.jpg It is also important to remember that the technology works only when the camera, radar, or sensors can identify objects ahead. Bright sunlight, heavy rain, caked-on snow, darkness, and other variables affect automatic emergency operation. car braking system.jpg Therefore, it is not a replacement for attentive driving. Rather, it is a safety net. braking in car.jpg
