The invention provides a speed curve replanning control method and device, a vehicle and a medium, and relates to the technical field of vehicles, the method is applied to a vehicle deployed with a PECC, when the vehicle is controlled to run according to a first speed curve planned by the PECC, according to position information of adjacent vehicles at multiple sampling moments, the first speed curve is calculated according to the position information of the adjacent vehicles at multiple sampling moments; a first trajectory of an adjacent vehicle during a future time period is predicted. Then determining a second trajectory of the vehicle in a future time period; and determining driving information of the vehicle and the adjacent vehicle according to the first track and the second track. Finally, according to the driving information, re-planning of the first speed curve is triggered. Wherein the driving information is used for indicating whether the vehicle collides with the adjacent vehicle or not. According to the technical scheme, the timeliness and accuracy of re-planning of the speed curve are effectively guaranteed, and the problem of repeated re-planning is solved.

    本申请提供一种速度曲线重新规划的控制方法、装置、车辆及介质,涉及车辆技术领域,该方法应用于部署有PECC的车辆,在控制车辆按照PECC规划的第一速度曲线行驶时,首先根据多个采样时刻下相邻车辆的位置信息,预测相邻车辆在未来时间段的第一轨迹。之后确定车辆在未来时间段的第二轨迹;根据第一轨迹以及第二轨迹,确定车辆和相邻车辆的行驶信息。最后,根据行驶信息,触发对第一速度曲线的重新规划。其中,行驶信息用于指示车辆和相邻车辆是否会发生碰撞。本技术方案有效的保证了对速度曲线进行重新规划的及时性和准确性,解决了多次重复重新规划的问题。
