  • Patent number: 9925963
    Abstract: Disclosed herein are an autonomous emergency braking system and a method of controlling the same, capable of autonomously performing emergency braking using information detected by a radar sensor. The autonomous emergency braking system includes a radar sensor and an ECU. The radar sensor transmits a radio wave and receives a wave reflected from an object in front of a vehicle, so as to detect the object in front of the vehicle. The ECU receives object detection information from the radar sensor, and stops or puts off autonomous emergency braking when the number of times the object is detected within a predetermined distance is equal to or greater than a predetermined number of times, based on the received object detection information.
