PURPOSE: A method for analyzing steering stability of a vehicle is provided to analyze a steering stability at a sudden transition area by using fuzzy steering angle control algorithm. CONSTITUTION: A vehicle model for a vehicle to be analyzed is prepared(S1). Then, input parameters and fuzzy groups are determined for a vehicle lane change analysis(S2). After that, a function of the fuzzy groups is determined(S3). Then, a fuzzy control rule is represented(S4). After performing a fuzzy deduction(S5), an optimal steering angle for each vehicle model is determined(S6). Then, the optimal steering angle is inputted into the steering wheel of each vehicle model(S7). After that, steering stability of each vehicle is analyzed according to the steering angle(S8).
