摘要：

总结了电动汽车传动系统的结构布置情况及电动汽车差速系统研究的两个方向——自适应差速的特殊电机设计和基于各种控制理论采用差速控制策略的电子差速系统设计。阐述了自适应差速系统的结构及其差速原理,并详细阐述了电子差速系统的控制结构、控制模型、控制变量及控制策略,同时对目前电子差速系统选择电机转速和转矩作为控制变量的利弊进行了探讨。最后,展望了电动汽车差速系统的发展前景。

Abstract:

A simple summary was carried out for the powertrain's structure of the electric vehicle. Based on this, another detailed summary was carried out for two ways of the differential research. One way was designing the special motor with self adaptive differential system, and another way was designing the electronic differential which was based on kinds of control theories. An exposition was made upon the structure and the principle of the self adaptive differential. And another detailed exposition was made upon the structure, model, object and the control strategy of electronic differential. The advantages and disadvantages of the motor's rotational speed and torque which were chosen for the control objects were discussed. In the end, the developing prospects of the electric vehicle's differential were discussed.
