- 차량의 주행 안정성 제어방법에 있어서,차량 선회시 차속센서와 조향각센서를 이용하여 차량의 차속과 조향각을 검출하는 단계;상기 검출된 차속과 조향각을 이용하여 운전자가 원하는 선회속도를 산출하는 단계;상기 산출된 운전자가 원하는 선회속도와, 상기 검출된 차속과 조향각에 의해 정해지는 선회속도게인을 이용하여 운전자가 원하는 차체횡가속도를 산출하는 단계;횡가속도센서를 이용하여 차량의 실제 차체횡가속도를 검출하는 단계;상기 산출된 운전자가 원하는 차체횡가속도와 상기 검출된 실제 차체횡가속도를 비교하여 차이값을 산출하는 단계;상기 산출된 차이값을 근거로 하여 주행 차량의 노면상태를 판단하는 단계; 및상기 판단된 노면상태에 따라 엔진의 출력을 제어하는 단계;를 포함하는 것을 특징으로 하는 차량의 주행 안정성 제어방법.
- 제 1항에 있어서,상기 노면상태를 판단하는 단계에서 상기 산출된 운전자가 원하는 차체횡가속도와 실제 차체횡가속도의 차이값이 미리 설정된 기준값 이상인 경우 상기 주행 차량의 노면상태를 저마찰계수노면으로 판단하는 것을 특징으로 하는 차량의 주행 안정성 제어방법.
- 제 2항에 있어서,상기 주행 차량의 노면상태가 저마찰계수노면이면, 상기 주행 차량의 엔진출력을 감소시키는 것을 특징으로 하는 차량의 주행 안정성 제어방법.
