The invention discloses a vehicle speed adjusting method and device, a vehicle and a storage medium. The method comprises the steps that environment data of the current vehicle are acquired; wherein the environment data comprises information of the obstacle object; when the obstacle object is judged to be a crossing object according to the path planning information of the current vehicle and the information of the obstacle object, determining a first area mapped by the obstacle object in a first speed planning graph of the current vehicle according to the information of the obstacle object and the path planning information; extending a first area, mapped in a first speed planning map of the current vehicle, of the obstacle object left and right in the time direction to obtain a second area; and adjusting the first speed planning graph of the current vehicle according to the second area to obtain a second speed planning graph of the current vehicle. According to the scheme, the speed of the current vehicle can be adjusted according to the condition of the obstacle object, the problem that the obstacle object is neglected in the automatic driving process is avoided, and the safety of automatic driving is improved.

    本发明公开一种车辆速度调整方法、装置、车辆及存储介质,方法包括:获取当前车辆的环境数据;其中,环境数据包括:障碍对象的信息;当根据当前车辆的路径规划信息以及障碍对象的信息,判断障碍对象为横穿对象时,根据障碍对象的信息以及路径规划信息,确定障碍对象在当前车辆的第一速度规划图中映射的第一区域;将障碍对象在当前车辆的第一速度规划图中映射的第一区域沿时间方向左右延伸,得到第二区域;根据第二区域,对当前车辆的第一速度规划图进行调整,得到当前车辆的第二速度规划图。即本发明的方案,能够根据障碍对象的情况调整当前车辆的速度,避免了自动驾驶过程中忽视障碍对象的问题,提升了自动驾驶的安全性。
