The invention discloses a passenger and freight collinear train cooperative driving strategy optimization method based on distributed model predictive control. The method comprises the steps of 1, establishing a basic train dynamics model; 2, designing a train operation control target; and step 3, designing a local optimization problem. And step 4, designing an energy-saving cooperative control DMPC algorithm of the passenger and freight collinear train. According to the method, control targets, constraint conditions and energy-saving optimization problems of the passenger train and the freight train are designed, and the energy-saving speed track of the whole train process under the dynamic operation condition can be obtained online by repeatedly solving the train energy-saving optimization control problem in each step. The method can optimize and adjust the train working diagram at the macroscopic level and the train control strategy at the microscopic level at the same time, and achieves the precise control of the train running speed.
