as the environmental protection and low-carbon electric vehicle has been more popular in the current social environment, and the research of electric drive vehicle is the inevitable trend of the development of electric vehicle industry in the future. with the rapid develop-ment of modern automobile technology, people will also have new requirements for the driving safety, maneuverability, smoothness and economy of the vehicle.

with the progress of science and technology, the mature technology of the traditional automobile can not fully support the new development. as a rather complex system, the dynamic structure of the automobile also needs further research, which can improve the safety and stability of the vehicle chassis dynamics control system from three aspects: longitudinal dynamics control, lateral dynamics control and integrated dynamics control^[3].

the main research object of this paper is distributed drive electric vehicle. the structure of distributed drive electric vehicle is to install the drive motor directly in or near the drive wheel, which has the outstanding advantages of short drive chain, high efficiency, compact structure and so on^[2]. after the new energy vehicle has been widely concerned, distributed drive vehicle is also the research focus of major automobile manufacturers and research institutes.
