摘　　要：四轮独立驱动电动汽车由于采用4个轮毂电机作为驱动电机,车轮的转速和转矩可以通过电机反馈得出,能够实现单个车轮的独立控制,在车辆控制策略制定、主动控制安全和制动能量回馈等方面具有明显优势。通过驱动力矩和和制动力矩的合理计算和分配控制以达到提高整车经济性能的目的;通过轮速补偿估算策略,使得四轮独立驱动电动车的滑转率计算更加准确,对于提高车辆行驶安全性具有十分重要的价值。Wheel independent drive electric cars thanks to four-wheel motor as the drive motor, wheel speed and torque can be obtained by the motor feedback, enables independent control of individual wheels, the vehicle control strategy development, security and active control of braking energy feedback so has obvious advantages. Reasonable and calculating the drive torque and braking torque distribution control and the vehicle to achieve improved economic performance of the ob- ject; wheel speed estimated by the compensation policy, so that four-wheel independent drive electric ears slip rate calcu- lation more accurately, to improve vehicle security has a very important value.
