The invention relates to the technical field of automatic driving, and discloses an efficient ecological driving trajectory tracking control method considering motion prediction deviation of surrounding vehicles, which comprises the following steps of: based on a motion prediction result of the surrounding vehicles under multi-vehicle interference, analyzing an error of predicted driving intentions and an error of predicted driving trajectories of the surrounding interference vehicles, and establishing a safe vehicle distance constraint condition; based on a multi-target long period-short time domain longitudinal and transverse track rolling optimization model, determining a rolling optimization vehicle speed and an optimization rotation angle of a self-vehicle motion track; and establishing a kinetic model of self-vehicle movement, establishing a cost function of longitudinal and transverse trajectory tracking control in combination with a safe vehicle distance constraint condition, and solving the cost function to realize trajectory tracking control. According to the efficient ecological driving trajectory tracking control method provided by the invention, stable tracking control of longitudinal and transverse optimization parameters is realized by accurately establishing a safe vehicle distance constraint condition, rolling optimization vehicle speed and optimization rotation angle, and the robustness of efficient ecological driving control under multi-vehicle interference is ensured.
