The invention discloses an adaptive cruise vehicle speed control method, system and device and a storage medium. The method comprises the steps that the first running speed of a current vehicle, the second running speed of a target vehicle and the first running distance between the current vehicle and the target vehicle are obtained; determining a first safe distance between the current vehicle and the target vehicle, and determining a sliding deceleration, a maximum deceleration and a maximum acceleration of the current vehicle; constructing a target optimization function about the first acceleration and the first deceleration, and constructing a driving constraint condition according to the first driving speed, the second driving speed, the first driving distance, the first safety distance, the sliding deceleration, the maximum deceleration and the maximum acceleration; and performing optimization solution according to the target optimization function and the driving constraint condition to obtain an optimal solution of the first acceleration and the first deceleration, and performing speed control on the current vehicle according to the optimal solution. The method improves the speed control efficiency of the self-adaptive cruise vehicle and the driving experience of the user, and can be applied to the technical field of vehicle control.

    本发明公开了自适应巡航车辆速度控制方法、系统、装置及存储介质,包括:获取当前车辆的第一行驶速度、目标车辆的第二行驶速度和当前车辆与目标车辆的第一行驶距离;确定当前车辆与目标车辆的第一安全距离,确定当前车辆的滑行减速度、最大减速度以及最大加速度;构建关于第一加速度和第一减速度的目标优化函数,根据第一行驶速度、第二行驶速度、第一行驶距离、第一安全距离、滑行减速度、最大减速度以及最大加速度构建行驶约束条件;根据目标优化函数和行驶约束条件进行优化求解得到第一加速度和第一减速度的最优解,根据最优解对当前车辆进行速度控制。本发明提高了自适应巡航车辆速度控制的效率和用户的行车体验,可应用于车辆控制技术领域。
