A vehicle speed and torque collaborative optimization control method for an intelligent networked PHEV comprises the following steps that (1) a vehicle single-shaft parallel type hybrid power system model is constructed according to vehicle driving limiting conditions; 2) collecting speed-time data of vehicle driving, and setting a boundary constraint factor; 3) analyzing the speed-time data of the time domain, and constructing a distance-speed two-dimensional space domain; 4) establishing a time domain model and a space domain model through a dynamic programming optimization method, and adding a gear shifting penalty function and a speed fluctuation penalty function to obtain a collaborative optimization algorithm model; and 5) obtaining a speed range of vehicle driving through the boundary constraint factor, and resolving through the collaborative optimization algorithm model to obtain the vehicle speed and torque collaborative optimization control method with the minimum cost. According to the invention, the problems of vehicle speed autonomous selection and power source torque coupling are solved, and the vehicle energy consumption economy is improved.
