| Abstract: | The stability of vehicle is an important factor for the security of driving, and therefore is becoming more noticed. In this article, the simulation of four-wheel steering vehicle (4WS) was studied in order to improve the handling stability. In this paper, the simulation module of simulink and so on is used to simulate the 4WS vehicle in double move line test, which has a proportional relationship between the front and rear steering angle, and then the steering angle and vehicle slip angle between the front wheel steering car and four wheel steering car with different linear proportion of steering angle is analyzed. At last conclusions were made in this paper. |
