In an advanced smart cruise system (10) according to the present invention, a smart cruise function is implemented by road surface-adaptive control in which wheel torque of a vehicle (1) is adjusted such that, when a speed bump (100-1) is recognized on a road image photographed by a camera or a radar, a squat effect is generated in the vehicle (1) when a front wheel of the vehicle (1) passes through the speed bump (100-1), and a dive effect is generated in the vehicle (1) when a rear wheel passes through the speed bump (100-1). Accordingly, riding comfort is improved due to a center of gravity of the vehicle (1) which is maintained substantially when the vehicle (1) passes through the speed bump (100-1), and particularly, weight and price advantages are obtained in comparison with a case of applying a hydraulic cylinder, due to wheel torque control performed by an engine and a brake.

    본 발명의 어드밴스 스마트 크루즈 시스템(10)은 카메라나 라이다로 촬영된 도로 영상에서 과속방지턱(100-1)이 확인되면, 차량(1)의 앞바퀴가 과속방지턱(100-1)을 통과할 때 차량(1)에 스쿼드 현상(Squat Effect)이 발생되고 이어 뒷바퀴가 과속방지턱(100-1)을 통과할 때 차량(1)에 다이브 현상(Dive Effect)이 발생되도록 차량(1)의 휠 토크 조절이 이루어지는 노면 적응성 제어로 스마트 크루즈 기능을 구현함으로써 과속방지턱(100-1)의 통과 시 거의 일정하게 유지되는 차량(1)의 무게중심으로 승차감을 향상시키고, 특히 엔진과 브레이크에 의한 휠 토크 제어로 유압실린더 적용 대비 중량 및 가격 우위를 갖는 특징이 있다.
