The invention provides a vehicle speed limit adjusting method and device. The adjusting method comprises the steps that the initial speed limit of a vehicle is determined; the initial speed limit is the initial speed limit corresponding to the position where the current vehicle runs; determining a steering speed limit of the vehicle; the steering speed limit is a speed limit obtained based on the steering capability of the vehicle; determining a minimum of the initial speed limit and the steering speed limit of the vehicle as a steering safety speed limit of the vehicle; determining a traffic efficiency speed limit of the vehicle based on a steering safety speed limit of the vehicle and the speed limit relaxation factor; interpolating the speed limit sequence of the current driving position of the vehicle in the target planning path to obtain the path speed limit of the vehicle; a minimum value of the traffic efficiency speed limit and the path speed limit of the vehicle is determined as a speed limit of the vehicle. By adopting the technical scheme provided by the invention, the safety, comfort and passing efficiency of the vehicle are improved.

    本申请提供了一种车辆的速度限制的调整方法及装置,所述调整方法包括:确定车辆的初始速度限制;所述初始速度限制为当前车辆所行驶的位置对应的初始速度限制;确定车辆的转向速度限制;所述转向速度限制为基于车辆转向能力所得到的速度限制;将车辆的初始速度限制和转向速度限制中的最小值确定为车辆的转向安全速度限制;基于车辆的转向安全速度限制和限速松弛因子确定车辆的通行效率速度限制;将当前车辆所行驶的位置在目标规划路径的速度限制序列插值得到车辆的路径速度限制;将车辆的通行效率速度限制和路径速度限制中的最小值确定为车辆的速度限制。采用本申请提供的技术方案,提升了车辆的安全性、舒适性和通行效率。
