英文摘要：

The in-wheel motor drive electric vehicle is a novel electric car and the study of driving-control system is an important direction of its research. For the study of the control algorithm relevant to the driving of multi--axle-driven electrical vehicles with in-wheel motors, a test beneh with drive-train and a control -monitoring system based on TI＇C200 was designed. By using the test bench, a series of tests about the running characteristics of in-wheel motors and the vehicle driving-control strategy were conducted. A new differential control strategy was proposed which was based on Ackerman mode, and then was determined through the simulation analysis by Matlab/Simulink software, and then was verified on the test-bed. The experiments show that the test- bench can meet the requirements well, and do some help to the hub motor performance and the research of the vehicle control strategy, and lay the foundation to the future work.
