The invention relates to a dangerous lane changing driving behavior prediction and early warning system and method, and the method comprises the steps: collecting historical physiological signals of a driver, collecting historical steering wheel steering angle data, obtaining historical surrounding environment information, constructing an input matrix, and training a deep learning model as a training sample, constructing a lane changing behavior prediction model; physiological signals of a driver and steering wheel steering angle data are collected in real time, surrounding environment information is obtained in real time, the lane changing behavior prediction model is input, and a current lane changing intention is obtained; and according to the state information of the current target vehicle and the surrounding vehicles, predicting the future motion trails of all vehicles, determining the current lane changing risk in combination with the current lane changing intention, and carrying out corresponding early warning prompt. Compared with the prior art, the method has the advantages that the lane changing intention can be better predicted in a short time, lane changing risk judgment is carried out in combination with the future motion trail, the dangerous lane changing behavior can be accurately predicted in time, and corresponding early warning is carried out.
