Research on Control Algorithm for DYC and Integrated Control with 4WS

2009 International Conference on Computational Intelligence and Natural Computing, 2009
The best advantage of the DYC is it can greatly improve vehicle handling and stability. It is proposed integrated control of four wheel steering systems (4WS) and direct yaw moment control. A desirable vehicle model is established with the best performance of side slip angle and yaw rate.

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

IEEE Transactions on Vehicular Technology, 2018
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.

Research on Vehicle Stability Based on DYC and AFS Integrated Controller

Applied Mechanics and Materials, 2013
A new vehicle stability control method integrated direct yaw moment control (DYC) with active front wheel steering (AFS) was proposed. On the basis of the vehicle nonlinear model, vehicle stable domain was determined by the phase plane of sideslip angle and sideslip angular velocity.

Researches on 4WIS-4WID Stability with LQR Coordinated 4WS and DYC

2020
Four-wheel independent steering and four-wheel independent driving electric vehicle (4WIS-4WID EV) has more control degrees of freedom (DOF). It benefits to realize torque allocation and differential steering control. Therefore, four wheel steering technology (4WS) and direct yaw control (DYC) are important research direction of vehicle stability. This

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 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 ...
