摘 要 ；；； Research on electric vehicle driving mode and driving motor Abstract With Chinas growing air pollution and the serious shortage of oil resources,the development of electric vehicles has become a national strategy. Many domestic universities, research institutes and automotive companies have invested great efforts to participate in the development of electric vehicles and has made a number of breakthroughs. Compared with the traditional Internal-combustion engine Vehicle, the wheel motor electric vehicle has a great advantage:greatly simplified mechanical drive,excellent drive efficiency and diverse drive mode.In this paper, the research object is the wheel motor and the matching of the electric vehicle drive system is important. Firstly, this paper outlines the significance of the topic and the development of electric vehicle technology at home and abroad.Secondly, the electric vehicle structure and the driving mode of the electric vehicle are described, and the outer rotor wheel motor is selected.Then all kinds of motors of electric vehicle are studied and discussed.The motor is divided into two types according to DC and AC, and the permanent magnet brush-less DC motor is chosen as the wheel motor.After selecting the drive mode and the type of motor, the motor parameters of the wheel motor are designed by Zhidou electric vehicles.At last, the simulation of electric vehicle is carried out by using the most popular electric vehicle simulation software ADVISOR 2002.The rationality of the design is verified.
