The present invention provides an auto-cruise control method for a vehicle, which comprises: a first step of receiving first grade data output from a digital road map and receiving second grade data corresponding to the current position of a vehicle from a slope sensor; a second step of comparing the first grade data with second grade data; a third step of determining a deviation from a set route when the first grade data is different from the second grade data and confirming whether the first grade data is updated to the second grade data; and a fourth step of determining the grade condition on the front side by using the second grade data when the first grade data is not updated to the second grade data and controlling a vehicles speed to correspond to the grade condition by using an optimum speed output profile, which is pre-stored. According to the present invention, it is possible to reduce driver inconvenience resulting from control of a vehicle speed that is unsuitable for the actual grade of a roadway.

    본 발명은 디지털 도로맵에서 출력되는 제1구배 데이터를 전달받고, 슬로프 센서로부터 현재 차량 위치에 해당하는 제2구배 데이터를 전달받는 제1단계와 상기 제1구배 데이터와 상기 제2구배 데이터를 비교하는 제2단계와 상기 제1구배 데이터와 상기 제2구배 데이터가 다른 경우, 설정된 경로를 이탈한 것으로 판단하여 상기 제1구배 데이터를 상기 제2구배 데이터로 갱신할 지 여부를 확인하는 제3단계 및 상기 제1구배 데이터가 상기 제2구배 데이터로 갱신되지 않는 경우, 상기 제2구배 데이터를 이용하여 전방의 경사 추세를 판단하고, 기저장된 최적 속도 프로파일 출력로직을 이용하여 상기 경사 추세에 해당하도록 차량 속도를 제어하는 제4단계를 포함한다.
