The invention relates to a vehicle speed control method based on vehicle-road cloud collaborative optimization. The method specifically comprises the steps that S1, a vehicle-road cloud collaborative positioning module calculates the real-time position of a vehicle according to multi-source positioning information, and calculates the real-time distance from the vehicle to a signal lamp of a front intersection; S2, according to the real-time position of the vehicle, the vehicle-road cloud collaborative sensing module calculates a suitable vehicle speed interval in which a signal lamp is green when the vehicle passes through a corresponding intersection through multi-source sensing information; S3, a cloud prediction control module calculates and obtains the real-time optimal vehicle speed according to the proper vehicle speed interval through a vehicle speed optimization target model based on fuel oil/energy consumption economy; and S4, the real-time optimal vehicle speed is fed back to a cloud controller, the cloud controller sends the real-time optimal vehicle speed to the vehicle end controller, the vehicle end controller carries out control according to the real-time optimal vehicle speed, the steps S1 to S3 are repeated, and vehicle speed rolling optimization is achieved. Compared with the prior art, the method has the advantages that the consumption rate of vehicle fuel oil/energy consumption is reduced, the traffic efficiency of a traffic road is improved and so on.
