Energy management for four-wheel independent driving vehicle

2010 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2010
The promising electric vehicle (EV) technology is a direction to tackle the global non-renewable energy problem. However, the efficiency to use the electric energy still needs deliberate research. Traditional EV has no choice to manage its energy flow, because it has only one traction motor. With the robotic research in 4 wheel independent drive (4WID),

Dynamic Control for Four-Wheel Independent Drive Electric Vehicle

2012 International Conference on Computer Science and Electronics Engineering, 2012
Due to the superiority of structure, four wheel independent drive electric vehicle (4WID EV) provides great potential for direct yaw control. In the process of driving, its very necessary to detect and suppress the tire skid in real time. In order to suppress the tire skid and achieve reasonable torque allocation, a novel method is proposed to detect ...

Coordinated Active Steering and Four‐Wheel Independently Driving/Braking Control with Control Allocation

Asian Journal of Control, 2015
AbstractThis paper presents a hierarchical coordinated control algorithm for integrating active front steering and four‐wheel independently driving control. In the higher‐level controller, an adaptive siding mode control law and a coordination law for adjusting the yaw rate and slip angle control priorities are applied to determine the desired front ...
