For the dynamic multi-objective requirements of yaw maneuverability and lateral stability under different driving states,an adaptive control strategy for vehicle yaw stability is proposed. Firstly,the vehicle dynamics model is established by piecewise linear fitting technology,and the dynamic stability region boundary related to road adhesion and longitudinal velocity is obtained in phase plane by integrated application of improved two-line method and fuzzy theory. Then,the stability risk during vehicle driving is quantitatively characterized and the dynamic multi-objective mapping function is introduced to adjust the built-in parameters of the stability control strategy designed based on the model predictive theory so as to match the dynamic multi-objective demand of vehicle lateral stability,yaw maneuverability and actuator energy consumption. Finally,the simulation test results prove that the designed control strategy can help the vehicle obtain safer and better stability control effect than the traditional method under various conditions.
