The invention relates to the technical field of automobile control, in particular to a self-adaptive cruise method and device and a medium. The to-be-planned road section is divided into a plurality of short-distance windows, the optimal vehicle speed of the starting point of each short-distance window is determined in a reverse derivation mode through the dynamic planning algorithm, the complete vehicle speed change curve is generated through the discrete vehicle speed values of all points, and vehicle speed planning of the to-be-planned road section is achieved. The MPC controller controls the vehicle to run according to the vehicle speed plan; in the reverse derivation process, the two indexes of the energy consumption index and the consumed time are considered through the first target function, and the energy consumption performance of the vehicle is remarkably optimized on the basis of meeting the driving requirement.
本发明涉及汽车控制技术领域,特别涉及一种自适应巡航方法、装置及介质。本发明将待规划路段划分为若干短距离窗口,采用动态规划算法以逆向推导的方式确定每段短距离窗口起点的最优车速,以离散的各点车速值生成完整的车速变化曲线,实现了待规划路段的车速规划,再通过MPC控制器控制车辆按车速规划行驶;逆向推导过程中通过第一目标函数考虑到了耗能指标和所耗时间两个指标,在满足行驶需求的基础上显著优化了车辆的能耗表现。
