The invention relates to the technical field of automobile automatic obstacle avoidance, in particular to an intelligent networked automobile automatic obstacle avoidance method and system.The method comprises the steps that the lateral speed and the tire pressure of an intelligent networked automobile at all moments during driving and the standard lateral speed of the intelligent networked automobile at all moments during driving at the standard tire pressure are collected; forming a lateral speed sequence and a tire pressure sequence of each moment by using the lateral speed and the tire pressure of each moment and all moments before the moment, and extracting each detection lateral subsequence in the lateral speed sequence of each moment; determining the lane changing confidence coefficient of each detection lateral sub-sequence; classifying the mean values of the tire pressure sequences at all the moments and the historical moments thereof to obtain a tire pressure cluster where the mean values of the tire pressure sequences at all the moments are located; determining the tire pressure interference degree of the tire pressure cluster; obtaining a lateral adjustment coefficient of the tire pressure cluster at each moment; and obtaining the lateral speed of the intelligent networked automobile at each moment in the lane changing and obstacle avoiding process. Therefore, the safety of automatic obstacle avoidance of the automobile is improved.
