A Simulation of the Four-Wheel Steering Vehicle Stability Based on DYC Control

2009 International Conference on Measuring Technology and Mechatronics Automation, 2009
In order to improve the lateral stability of the vehicles at a high speed, a DYC control method is applied to four-wheel steering vehicle control. Through model tracking method, a feedback controller which used direct yaw moment as the controlled output based on fuzzy control theory is designed, meanwhile, classic 4WS control as a feed forward is used ...

Integrated stability control of AFS and DYC for electric vehicle based on non-smooth control

International Journal of Systems Science, 2018
A controller which ensures the driving stability of a four-wheel-independent-drive electric vehicle (4WID-EV) is designed in this paper. The controller is structurally hierarchically designed.

Integrated AFS/DYC sliding mode controller for a hybrid electric vehicle

International Journal of Vehicle Design, 2011
A multi-layer integrated controller of active front steering and direct yaw moment is developed in this study. In the upper layer, the corrective steering angle and yaw moment are obtained using Sliding Mode Control (SMC) with combined sliding surface. The corrective yaw moments are applied by electric motors embedded in rear wheels.

Integrated AFS and DYC Sliding Mode Controller Design for Hybrid Electric Vehicle

ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 3, 2010
An integrated controller of active front steering and direct yaw moment is developed in this paper. In upper layer, the corrective steering angle and yaw moment are obtained using sliding mode control. A combined sliding surface is defined in order that the yaw rate and side slip angle of vehicle track the desired values. The corrective yaw moments are

A research of DYC for independent 4WD EV based on control target dynamic regulated

2007 IEEE International Conference on Vehicular Electronics and Safety, 2007
A direct yaw-moment control (DYC) method based on the control target dynamic regulated is proposed to achieve integrated optimization between stability and maneuverability for the DYC system of independent 4WD EV. Firstly, the integrated control target for the stability and maneuverability is determined with the improved 2DOF bicycle model. Furthermore

Vehicle Lateral Dynamics Control Through AFS/DYC and Robust Gain-Scheduling Approach

IEEE Transactions on Vehicular Technology, 2016
In this paper, we investigate the combined active front-wheel steering/direct yaw-moment control for the improvement of vehicle lateral stability and vehicle handling performance. A more practical assumption in this work is that the longitudinal velocity is not constant but varying within a range.

4WS and DYC coordinated control for 4WS-4WID autonomous vehicles considering tire nonlinearity

ISA Transactions
To address the issue of path tracking and stability of four wheel steering and four wheel independent drive (4WS-4WID) autonomous vehicles under extreme conditions, this paper proposes a coordinated control method for four wheel steering (4WS) and direct yaw moment control (DYC).
