The invention relates to the technical field of vehicle steering system control, in particular to a vehicle intelligent obstacle avoidance method and system based on a vehicle AI platform, and the method comprises the steps: obtaining driving information data of a vehicle in a driving process, and obtaining a braking adhesion coefficient of an intelligent vehicle based on the driving information data; according to the Euclidean distance between the position of the intelligent vehicle at each moment and the position of the nearest obstacle and the difference between the driving direction angle of the intelligent vehicle at each moment and each search extension angle, determining a direction excellent value of each search extension angle of the intelligent vehicle at each moment; and in combination with the spatial distribution condition of the obstacles in each obstacle neighborhood at each moment, the search priority of each search extension angle of the intelligent vehicle at each moment is obtained, a fast search random tree algorithm is utilized to obtain an obstacle avoidance path planning route of the intelligent vehicle, and vehicle steering is controlled and adjusted. The steering of the vehicle can be regulated and controlled in time when the vehicle avoids obstacles, and the accident risk of the vehicle is reduced.
