The invention discloses a vehicle trajectory tracking and stability coordination control method considering roll. The method comprises the following steps: 1) constructing a vehicle four-degree-of-freedom dynamics linearization model; 2) based on the vehicle four-degree-of-freedom dynamics linearization model, constructing an MPC prediction model; 3) constructing a coordination control objective function and constraint conditions based on the MPC prediction model; and 4) based on the coordination control constraint condition, solving the coordination control objective function to obtain a vehicle four-wheel driving force optimal distribution scheme. According to the invention, trajectory tracking and stability coordination control under the emergency working condition can be realized.
