The present invention provides a safety steering force assistance system for a vehicle, which comprises: a sensor module measuring a distance between a front vehicle and a driver′s vehicle; an MDPS module operating a steering wheel with a motor; and a control module comparing an expected braking distance calculated on the basis of the distance between two vehicles and a vehicle speed when a signal to slam on the brakes is inputted while driving in a random flex steering mode, calculating a steering angle range when the expected braking distance is longer than the distance between two vehicles, and varying a steering force of the MDPS module to respond to the steering angle range.

    본 발명은, 전방차량과의 차간거리를 측정하는 센서모듈, 모터로 스티어링 휠을 동작하는 MDPS 모듈 및 임의의 플렉스 스티어링 모드로 주행 중 급브레이크 신호가 입력되면, 상기 차간거리 및 차량속도를 기반으로 산출한 예상제동거리를 비교하여, 상기 예상제동거리가 상기 차간거리보다 길면 조향각도범위를 산출하고, 상기 조향각도범위에 대응되게 상기 MDPS 모듈의 조타력을 가변시키는 제어모듈을 포함하는 자동차의 안전 조타력 보조시스템을 제공한다.
