The invention discloses an integrated automatic emergency brake-by-wire system and method, relates to the field of automobiles, and can enable control strategies of a vehicle-mounted emergency intelligent collision avoidance system to be easy to cooperate. The system comprises a camera sensor, a millimeter wave radar sensor, an automatic emergency braking drive-by-wire unit, a hydraulic control unit and an electric cylinder unit. The camera sensor is connected with the automatic emergency braking drive-by-wire unit and transmits collected image information of a target object in front of a vehicle to the automatic emergency braking drive-by-wire unit. The millimeter wave radar sensor is connected with the automatic emergency braking drive-by-wire unit and transmits detected point cloud picture information of a target object in front of a vehicle to the automatic emergency braking drive-by-wire unit. A visual perception unit and a drive-by-wire brake unit are arranged in the automatic emergency brake drive-by-wire unit; the automatic emergency braking drive-by-wire unit is configured to receive and process image information, collected by the camera sensor, of a target object in front of the vehicle, receive data, collected and processed by the millimeter wave radar sensor, of the target object in front of the vehicle, and perform fusion processing and judgment with a visual perception result output by the visual perception unit; and sending a brake request signal to the brake-by-wire unit. The hydraulic control unit and the electric cylinder unit are respectively connected with the automatic emergency brake drive-by-wire unit, and the drive-by-wire brake unit builds pressure through the electric cylinder unit and completes braking.
