The invention discloses a vehicle collision early warning method and system and electronic equipment, and the method comprises the steps: obtaining a historical interaction data set of a test vehicle and a target vehicle based on a vehicle-to-vehicle communication V2V technology; training an SVM-RFE model by using the historical interaction data set to obtain a lane changing intention prediction model; constructing a vehicle track prediction model of a long and short term memory (LSTM) network; acquiring real-time interaction data of the test vehicle and the target vehicle; when the lane changing intention prediction model identifies that the test vehicle has a lane changing intention according to the real-time interaction data, the vehicle track prediction model is used for predicting the longitudinal displacement and the transverse position of the test vehicle and the target vehicle within the set time; and according to the longitudinal displacement and the transverse position of the test vehicle and the target vehicle within the predicted set time and the real-time interaction data, whether the test vehicle collides during lane changing is judged based on a convex polygon collision detection technology. The early warning timeliness and accuracy of typical risk scenes can be improved, and the false alarm rate is reduced.
