Auto braking technologies combine sensors and brake controls to help prevent high-speed collisions. Some automatic braking systems can completely avoid collisions, but most of them are designed to simply reduce the vehicle’s speed before it collides with anything. Because high-speed crashes are more likely to be fatal than low-speed ones, automatic braking systems can save lives and reduce the damage to property that occurs during an accident. Some of these systems provide braking assistance driver, and others are actually capable of activating the brakes without driver input.
How do automatic braking systems work?
Each car manufacturer has its own automatic brake system technology, but they all rely on some type of sensor input. Some of these systems use lasers, others use radar, and some even use video data. This sensor input is then used to determine if there are any objects in the vehicle’s path. If an object is detected, the system can then determine if the vehicle’s speed is greater than the speed of the object in front of it. A significant difference in speed may indicate the possibility of a collision, in which case the system may automatically apply the brakes.
In addition to directly measuring sensor data, some automatic braking systems can also use GPS data. If the vehicle has an accurate GPS system and access to a database of stop signs and other information, it can activate its automatic brakes if the driver does not inadvertently stop in time.
Do I really need automatic brakes?
All of this happens without driver intervention, so you don’t have to drive a car with automatic brakes any differently than you would drive any other car or truck. If you stay vigilant all the time, you will probably never notice that your car even has an automatic braking system.
However, automatic brakes can save your life if you ever suffer from a momentary drop in concentration. Automatic braking systems are primarily designed to protect against distracted driving and the technology could also save lives if the driver falls asleep at the wheel. Many drivers will never need to use this type of system, but it’s still a good safety net.
What systems use automatic brakes?
The main use of automatic brakes in systems collision avoidance . These systems are usually able to warn the driver of an impending collision, tighten seat belts, and take other actions that can help prevent an accident or mitigate damage during a collision.
In addition to pre-collision avoidance systems in many adaptive systems cruise control automatic brakes are also used. These systems are able to measure the speed of the lead vehicle and compare it. They can also slow down by cutting off the gas, shifting gears, and finally applying the brakes.
