The invention discloses a vehicle intersection passing assisting method and system and a vehicle, and the method comprises the steps: detecting coarse-granularity intersection information based on SD navigation information and low-precision positioning information, and carrying out the fine-granularity positioning of an intersection based on the detected coarse-granularity intersection information and visual perception information. The method comprises the following steps: recording and storing perception data based on intersections subjected to fine granularity positioning, recording realization based on perception triggering on-line fusion, splicing the stored perception data into incremental topological graphs of the intersections based on offline post-processing, storing the incremental topological graphs, splicing the incremental topological graphs based on visual flow information fusion, and carrying out visual flow information fusion on the basis of visual flow information fusion. The visual flow information comprises lane line information, navigation information and/or positioning information, triggering the stored increment topological graph of the intersection based on the process of detecting and confirming that the vehicle passes through the intersection, and assisting the vehicle to pass through the intersection based on the increment topological graph of the intersection. According to the invention, the performance of safely passing the intersection by the user aiming at the familiar route is effectively solved or improved to a certain extent, and the user experience is improved.
