英文摘要： Cooperative lateral and longitudinal control of electric vehicles merging with traffic informations through interacting and sharing informations such as road traffic environment and vehicle motion states between electric vehicles, intelligent transportation system(ITS) and grid system, is one of the important research directions of dynamical control for electric vehicles in the future. This project first establish dynamical model,which can accurately simulate behavior mechanism of vehicles based on ITS. Secondly, the lateral and longitudinal dynamical characteristics and coupling mechanism of electric vehicles in intelligent transportation system is revealed, and control objective function which can comprehensively coordinate the performances of safety,efficiency and comfort is determined.Then,a new cooperative control method of electric vehicles merging with traffic informations is presented using hierarchic control theory. Finally,the stability and robustness of the proposed control system is proved，and the performance of the proposed control system is tested.The research work in this project will be significant to achieve the multi-objective and multi-mode cooperative control of electric vehicles ,in which the driving safety,riding comfort and economical efficiency are considered, optimize the lateral and
