The invention discloses an intelligent networked automobile random prediction cruise control system, and belongs to the field of intelligent networked automobile energy-saving control. The invention aims to design an intelligent networked vehicle random prediction cruise control system considering future vehicle speed uncertainty. The system can predict a future speed sequence of a preceding vehicle in a cruise mode and quantify uncertainty, and integrates uncertainty information into optimization control of a vehicle following decision, thereby realizing an intelligent networked vehicle random prediction cruise control system capable of saving vehicle energy consumption. The method comprises the following steps: 1, ; information collection, establishing a control-oriented cruise control kinetic model; a preceding vehicle speed prediction model is established, future vehicle speed information of a preceding vehicle is predicted according to the preceding vehicle speed prediction model,an SMPC optimization control problem is described, the SMPC optimization problem is solved, vehicle speed control in cruise following is achieved, and vehicle energy-saving control in the rolling time domain is achieved based on SMPC. According to the method, online solving of the optimization problem with probability constraints is achieved, and energy consumption in the vehicle cruise process is reduced.
