The invention discloses a speed planning and energy management two-stage gear optimization control method for a networked hybrid vehicle, and belongs to the technical field of intelligent vehicle control. The invention aims to optimize gears in two levels of speed planning and energy management and in different time domains, so that the speed planning and energy management two-level gear optimization control method for the networked hybrid vehicle is realized. The method comprises the steps that an upper-layer speed trajectory optimization method with gears and engine oil consumption transmits an optimized speed target to a lower-layer energy management optimization control method with gear integers; and the lower layer is provided with a gear integer energy management optimization control method, and further optimization is carried out to obtain an energy distribution factor and a gear target between the engine and the motor. An urban traffic real-time pavement scene simulation test result shows that compared with an upper-layer and lower-layer traditional control method, the provided speed planning and energy management two-stage gear optimization method can effectively reduce fuel consumption.
