The invention relates to the technical field of vehicle collision recognition, in particular to a vehicle collision intelligent recognition method and system, terminal equipment and a storage medium, and the method comprises the steps: marking M speed limit points in a collision recognition area, and recognizing a lane and a motion state when a target vehicle is driven in; configuring a speed monitoring mechanism for the U highest speed limit points and the V lowest speed limit points respectively by utilizing a double linked list and a sliding time window technology; a collision risk identification model is constructed in combination with the vehicle state, and the collision risk result is sent to the target vehicle in real time, so that the technical problem that the collision risk cannot be accurately evaluated under the conditions of high-speed driving or dense traffic flow and large vehicle speed difference is solved, the establishment of the motion state simulation model of the vehicle is realized, and the reliability of the vehicle is improved. The dynamic characteristics of the target vehicle are accurately extracted by combining the acceleration and angular velocity data acquired by the IMU sensor, and the motion state of the vehicle can be more comprehensively and accurately analyzed, so that the technical effect of more effectively evaluating the collision risk is achieved.
