The invention is suitable for the technical field of auxiliary driving, and particularly relates to a ramp fuel-saving control method and system based on self-adaptive cruise, and the system comprises a sensing unit which is used for collecting road information and vehicle information; the calculation unit is used for calculating the acceleration and time information required by the increased target vehicle speed under the current working condition; the judgment unit is used for calculating the acceleration required to be output by the self-adaptive cruise control system to obtain a calculation result; and the control unit is used for adjusting the opening degree of an accelerator and the opening degree of a brake. According to the method, the front-view camera is used for recognizing the state of a road ahead, the relation between the acceleration generated by vehicle stress caused by a ramp within a set threshold time range and the acceleration calculated by the self-adaptive cruise system is judged according to the principle of vehicle dynamics when the vehicle is on the ramp road, and the acceleration and the acceleration are innovatively combined, so that the stability of the vehicle is improved. And the effect of fuel-saving driving of the vehicle on the ramp road is achieved.

    本发明适用于辅助驾驶技术领域,尤其涉及一种基于自适应巡航的坡道节油控制方法及系统,所述系统包括:感知单元,所述感知单元用于采集道路信息以及车辆信息;计算单元,所述计算单元用于计算出当前工况下增加的目标车速所需要的加速度以及时间信息;判断单元,所述判断单元用于计算自适应巡航系统需要输出的加速度,得到计算结果;控制单元,所述控制单元用于对油门开度和制动开度进行调节。本发明采用了前视摄像头识别前方道路状态,根据车辆动力学原理,判断车辆在坡道道路时,在设定的阈值时间范围,坡道所导致车辆受力而产生的加速度与自适应巡航系统计算的加速度之间的关系,并创新性的将两者结合,达到车辆在坡道道路时节油行驶的效果。
