The invention belongs to the technical field of vehicles, and discloses a cruise control method, device and equipment and a storage medium. The method comprises the following steps: determining aggressive acceleration values in a preset time period based on real-time driving data of a target vehicle, a target cruise speed of the target vehicle and a preset scale model; determining an acceleration target drop point interval according to the aggressive acceleration value, the target cruising vehicle speed and the current meter display vehicle speed in the real-time driving data; determining an acceleration jitter range according to the real-time driving data and a preset differential model; and performing acceleration jitter filtering according to the acceleration jitter range and the acceleration target drop point interval, and performing constant-speed cruise control according to a filtering result. By means of the mode, fine control over the longitudinal drive-by-wire acceleration in the constant-speed cruise process is achieved, vehicle shaking is reduced, meanwhile, the driving safety is further guaranteed, and the driving experience feeling of a user is improved.

    本发明属于车辆技术领域,公开了一种定速巡航控制方法、装置、设备及存储介质。本发明通过基于目标车辆的实时行驶数据、所述目标车辆的目标巡航车速以及预设比例模型确定预设时间段的激进加速度值;根据所述激进加速度值、所述目标巡航车速以及所述实时行驶数据中的当前表显车速确定加速度目标落点区间;根据所述实时行驶数据以及预设微分模型确定加速度抖动范围;根据所述加速度抖动范围和所述加速度目标落点区间进行加速度抖动过滤,根据过滤结果进行定速巡航控制。通过上述方式,实现了在定速巡航过程中对纵向的线控加速度的精细控制,减少了车辆抖动,同时进一步保证了行车安全性,提升了用户驾驶体验感。
