The invention is suitable for the technical field of intelligent traffic, and provides a real-time lane changing risk prediction method for a networked automatic driving vehicle and related equipment, and the method comprises the steps: obtaining historical lane changing track data of the networked automatic driving vehicle; generating a risk sample and a safety sample based on the historical lane changing trajectory data; dividing the generated samples into a training set and a verification set, and generating risk samples in the training set to obtain N new training sets; training the lane change risk prediction model by using the training set and the new training set, and calculating a precision improvement value; constructing a regression model according to the generated sample and the corresponding precision improvement value, and determining important features by using the regression model; the important features in the new training set are disturbed, the disturbed training set is used for training the lane changing risk prediction model, and a final lane changing risk prediction model is obtained; and performing lane change risk prediction by using the final lane change risk prediction model. According to the invention, the lane changing risk prediction accuracy of the networked autonomous vehicle can be improved.
