The invention relates to a model predictive control method for an electromechanical composite transmission vehicle. The method includes the steps that a system model, a future required torque algorithm and the like are used as prediction models according to the location of a driver pedal at the current sampling moment, in combination with the vehicle state signals such as the speed, the rotation speed of an engine and the state of charge (SOC) of a battery, and future vehicle required torque information from a self-adaption recursive prediction algorithm, a control command for components of the system within the control cycle is determined through model predictive control, and on-line optimal control is realized. Due to the fact that model predictive control takes the future vehicle requirement information and the optimized objective function performance within the predicted time domain into consideration comprehensively, it can be guaranteed that the optimal control quantity applied to the system currently has no adverse effects on future behaviors of the system, and a better control effect can be obtained.
