The invention relates to an auxiliary driving system self-adaptive adjustment method and system based on driving conditions. The method comprises the steps that multiple historical kinematics short segments are acquired; determining a plurality of first characteristic parameters of the plurality of historical kinematics short segments; processing the first characteristic parameter by adopting a principal component analysis method to obtain a processed characteristic parameter; classifying the processed characteristic parameters by adopting a K-Means clustering algorithm to obtain a classification result; obtaining a current kinematics short segment; determining a second characteristic parameter of the current kinematics short segment; determining the current working condition of the automobile according to the classification result and the second characteristic parameter; adjusting the auxiliary driving system according to the current working condition of the automobile. According to the method, self-adaptive adjustment is carried out on the auxiliary driving system, the problem that a driver does not have enough energy or enough related knowledge to complete switching of driving modes, adjustment of driving parameters, opening and closing of functions and other operations is solved, the safety of automobile driving is improved, and the operation load of the driver is reduced.
