Automatic braking is a technology for automobiles to sense and avoid an imminent collision with another vehicle, person or obstacle by braking without any driver input. Sensors to detect other vehicles or obstacles can include radar, video, infrared, ultrasonic or other technologies. GPS sensors can detect fixed dangers such as approaching the stop signs tAutomatic braking by the system after sensing an obstacle can be executed in two modes. In collision avoidance, the collision is avoided by the automatic braking, but the driver will not be warned by this type of system. There is a very good chance of wrongly interpreting the signals, especially in the case of radars or lasers. In a collision mitigation system, the sensors detect the possibility of collision but will not take immediate action. A warning will be sent to the driver in the form of a signal or a voice message. There is a threshold safe distance calculated by the system, and if the driver fails to respond even when the vehicle crosses that region, then only brakes will be applied automatically. Even if there is a mis-interpretation of signals, there is no problem, because the decision to apply brakes is left with the driver and the brakes are applied automatically only in the most emergency situations. Many vehicles are provided with the option of turning on or off the automatic system based on their surroundings. In some automobiles, even though they cannot be completely disabled, they can be limited to warning the driver about a coming obstacle. Even this emergency braking initiates ABS which help the driver to retain the control over vehicle without any skidding. An automatic braking system is only effective if the mode of sensing the obstacles is reliable, or else any kind of false interpretation may cause a lot of damage.hrough a location database.
