The present invention relates to an emergency avoidance driving system linked to a front vehicle brake and a method, which can promote a quick and accurate avoidance maneuver by being linked to a brake lamp of a front vehicle when a vehicle performs autonomous driving (autonomous driving mode, ACC mode, constant ACC operation) and by integrally using front radar and front-lateral radar to perform the avoidance maneuver. The emergency avoidance driving system is configured to: detect a lamp operation of the front vehicle through a front camera in a DCU during autonomous driving; automatically convert into an avoidance maneuver mode when the brake lamp operation of the front vehicle is detected; automatically convert into the avoidance maneuver mode when an object is detected by detecting the object through the front radar and a corner radar when the brake lamp operation of the front vehicle is not detected during autonomous driving; execute a vehicle stop by performing vehicle braking through a brake operation when the avoidance maneuver in vehicle lanes is not possible after checking whether the avoidance maneuver in vehicle lanes is possible after converting into the avoidance maneuver mode; and perform the avoidance maneuver through vehicle deceleration and steering control when the avoidance maneuver in vehicle lanes is possible to prevent a collision with a front object.

    차량이 자율주행 중(자율주행 모드, ACC 모드, 상시 ACC 작동) 전방 차량의 브레이크 램프 연동과 전방 레이더 및 전측방 레이더를 복합적으로 이용하여 회피 기동을 수행함으로써, 신속하고 정확한 회피기동을 도모하도록 한 전방 차량 브레이크 연동 비상회피 운전시스템 및 방법에 관한 것으로서, 자율주행 중 DCU에서 전방 카메라를 통해 전방 차량의 브레이크 램프 작동을 감지하고, 전방 차량의 브레이크 램프 작동이 감지되면 자동으로 회피기동모드로 전환하며, 자율주행 중 전방 차량의 브레이크 램프 작동이 감지되지 않으면 전방 레이더 및 코너 레이더를 통해 물체를 감지하여 물체가 감지되면 자동으로 회피기동모드로 전환하며, 회피기동모드로 전환한 후, 차로 내 회피 가능 여부를 확인하여 차로 내 회피기동이 불가능하면 브레이크 동작을 통해 차량 제동을 수행하여 차량 정차를 실행하고, 차로 내 회피기동이 가능하면 차량 감속과 조향 제어를 통해 회피 기동을 수행하여, 전방 물체와의 충돌을 방지한다.
