The invention discloses an intelligent driving automatic lane changing vehicle target collision detection method and module and a storage medium, the intelligent driving automatic lane changing vehicle target collision detection method comprises the following steps: establishing a specified coordinate system, and dividing a region where a vehicle may collide into dangerous regions; calculating collision time based on the relative acceleration, speed and distance of the own vehicle and the target vehicle; assigning collision time threshold values for different dangerous areas, judging lane-changing collision danger levels, and setting different danger gains for the lane-changing collision danger levels; during lane changing, variable gain time accumulation is carried out on the collision danger moment of the lane changing side, and a corresponding intelligent driving decision is made according to the accumulated time. According to the method, the detection complexity is reduced, the resource consumption is reduced, the calculation real-time performance is improved, the method can be applied to a low-calculation-power controller, and the method has wide application prospects and high market value for mass production of intelligent auxiliary driving functions such as automatic lane changing and the like.
