The invention relates to a predictive cruise control method and device for a centralized vehicle queue based on cloud control. Comprising the steps of obtaining real-time positions and pilot vehicle state information of a vehicle queue based on a received predictive cruise control request, and determining an optimal reference speed curve of the vehicle queue according to the real-time positions, the pilot vehicle state information, a preset fuel consumption model and a preset dynamic model, and taking the curve as the input of a centralized queue speed planning algorithm to carry out optimization solution to obtain the optimal driving speed of the vehicle queue, and sending the optimal driving speed to the vehicle queue to realize the cruise control of the vehicle queue. Therefore, by combining the advantages of the cloud, the problems of limited prediction range, insufficient information acquisition capability and the like of the existing vehicle queue predictive cruise are solved, the safety, economy and high efficiency of queue predictive cruise control are realized, the problem that the energy consumption of the following vehicle is gradually increased due to team formation is improved, the calculation pressure of the vehicle end is relieved, and the service life of the vehicle is prolonged. And the energy-saving capability of the queue and the safety and stability boundary capability of the system are improved.
