Directional stability and control of four-wheel independent drive electric vehicles

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2002
The innovative powertrain configuration of modern electric vehicles with four-wheel independent drive (4WID) provides the possibility of simple and exact yaw moment control by controlling the electric motor of every wheel independently. In this study, a genuine control strategy for optimum direct yaw moment control is proposed.

Safe Predictive Control of Four-Wheel Mobile Robot with Independent Steering and Drive

2021 American Control Conference (ACC), 2021
We propose a predictive controller that minimizes the trajectory error of a four-wheel mobile robot with independent steering and drive (4ISD) under safety constraints imposed by the presence of people. The 4ISD drivetrain is overactuated, that is, a given motion vector maps to multiple sets of actuation, not all of which are safe or optimal.

Trajectory Tracking Control of Four-Wheel Independent Drive Electric Vehicles

2020 IEEE 16th International Conference on Control & Automation (ICCA), 2020
A two layered control scheme is proposed to solve the trajectory tracking problem for a four-wheel independent drive electric vehicle (4WIDEV) in this paper. The first layered control is a control strategy producing front steering wheel angle and yaw moment that is designed by model predictive control (MPC) approach.

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),
