Yaw stability of 4WS with variable steering ratio strategy using inertial delay control based sliding mode control

Improving Handling Performance of a Four-Wheel Steering Vehicles Using LQR Controller

“…Compared to conventional 2WS, 4WS operates independently to direct the front and rear axles through curves based on the vehicle's state. Consequently, vehicle stability and active safety may be improved through four-wheel steering [5][6][7][8][9]. Most previous studies investigated how the 4WS system affected lateral stability in terms of yaw velocity, lateral acceleration, and lateral deviation; however, it did not explore how driver behavior affected the stability performance of the vehicle.…”

Research on automobile four-wheel steering control system based on yaw angular velocity and centroid cornering angle

“…Therefore, it remains an important topic to address how to further eliminate the vehicle's center of mass slip angle, make the yaw angle speed faster and stabilize, and make the vehicle's stability and steering better. [1][2][3][4] In recent years, more safe, comfortable, and easy to drive intelligent vehicles have become a major goal in the development of contemporary automobiles. With the rapid development of electronic technology, testing technology, system dynamics, and other disciplines, the control technology of vehicle 4WS system has developed rapidly.…”
