The invention discloses an automatic driving global speed planning method and system based on vehicle cloud collaboration, and the method comprises the steps: carrying out the slicing according to the slope condition of a global route, so as to obtain global sliced road information comprising a plurality of segments of segmented roads, secondly, combining historical optimal vehicle speed data of the same historical vehicle with the best driving fuel consumption performance in the same global route with global slice road information to obtain a suggested vehicle speed of the best fuel consumption corresponding to each segment of slice road, and then obtaining the position of the current vehicle in real time; then the slice road at the moment is obtained according to the real-time position, driving is carried out according to the suggested vehicle speed corresponding to the slice road at the moment, and speed planning is carried out from the global perspective, so that oil consumption needed for driving the whole global route is reduced, and economical efficiency is improved; the technical problem that the oil consumption or the time efficiency of the whole driving route cannot be optimized and reduced due to the fact that a speed planning mode in the prior art is microcosmic control planning for a certain driving road section and a certain traffic road condition is solved.

    一种基于车云协同的自动驾驶全局速度规划方法及系统,根据全局路线的坡度情况进行切片,以得到包括多段分片道路的全局切片道路信息,然后将在相同全局路线中行驶油耗表现最佳的相同的历史车辆的的历史最优车速数据结合全局切片道路信息可以得到每段分片道路对应最佳油耗的建议车速,然后实时获取当前车辆的所在位置,然后根据实时的位置得到此时所在的切片道路,按照此时所在的切片道路对应的建议车速进行行驶,从全局角度进行速度规划,以减少行驶完整个全局路线所需的油耗,提高经济性,解决了相关技术中存在的速度规划方式是针对某一行驶路段和某一交通路况进行微观上的控策规划,无法做到整个行驶路线的油耗或时效进行优化减少技术问题。
