The Analysis of 4WD Vehicle Overtaking Based on Electric Wheels

Abstract:

In order to improve vehicle overtaking performance, the four-wheel driving technology based on electric wheels is analyzed. A four-wheel driving vehicle model has been built with ADAMS software, and the control strategy has been built with Simulink software. The driver steering and speed control model with variable ratio is built. The comparative overtaking simulation of four-wheel driving with and without Direct Yaw Control is processed. With the simulation, it can be found that the centroid yaw-rate of the vehicle with Direct Yaw Control is smaller, and vehicle movement track is closer to target track than the vehicle without DYC. The manipulation performance of vehicle is improved, and the labor intensity of the driver is reduced. This provides a certain amount of theoretical research for the four-wheel driving technology based on electric wheels.
